Polygonmach’s Next-Generation Track-Mounted Crushing & Screening Equipment
Polygonmach is delighted to present a novel series of track-mounted mobile equipment to revolutionize the crushing and screening industry. This new generation – including crushers (jaw, impact, cone, VSI), screens (inclined and scalper types), and stacking conveyors – offers unparalleled mobility, quick installation, and high productivity for construction, mining, and recycling applications. Mounted on heavy-duty crawler tracks, the equipment can travel over uneven terrain and can be directly placed at job sites without the need for costly foundations or extended installation periods. Each unit features advanced engineering with efficiency in mind, hybrid diesel-electric drives, and compliance with existing environmental regulations. The result is a comprehensive mobile solution that maximizes productivity, minimizes operating costs and downtime for project contractors and industry professionals.
Each product in this track-mounted series is engineered for fast mobilization, easy movement around the site, and integration into an overall processing train with ease. Operators can move the crushers, screens, and stackers as a single system or individually and place them in the middle of the material flow for optimum efficiency. What follows is each model line of Polygonmach's track-mounted equipment – highlighting key models, technical details, and the specific applications for which they're optimally suited – to illustrate how these new machines can meet your project needs without compromise.
Track Mounted Screen Plants (PTS Series)
Polygonmach's track-mounted screening plants (PTS series) are robust mobile screens for precise aggregate screening and washing. Two models – PTS155 and PTS185 – cover capacities ranging from around 150 to 600 tons per hour depending on material and mesh size. They are equipped with an enormous vibrating screen (e.g. triple-deck 5.2×1.5 m on the PTS155) and onboard conveyors, all installed on a crawler base for easy movement between sites. The tracked PTS machines offer the advantage over static screens of being able to be easily moved to new positions in the pit or project, ideal for use in applications where regular repositioning is required or where working on uneven terrain.
Some of the significant features of the PTS screens include adjustable screen angles, heavy-duty construction for extended life, and simple controls for quick establishment of screen settings. The plants are often fitted with wet processing options (spray bars, pumps, hydrocyclones) to facilitate washing and dewatering of materials, delivering clean, in-spec aggregates in a single pass. Notably, Polygonmach uses a hybrid drive system throughout these track screens – i.e., the plant can run off diesel generator power or be plugged into mains electricity on site. The dual-power setup (with EU-sourced hydraulic track drives and IE3-class motors) boosts fuel efficiency and can reduce CO2 emissions by a considerable amount when electric power is plugged in.
Applications: Track screen plants find extensive use in mines and quarries for grading crushed stone into different products at high throughput rates. The mobility of track screen plants allows the screen to be placed near the crusher face, minimizing haul distances for loaders and optimizing throughput. They are equally valuable in construction and demolition recycling – the PTS screens can process mixed C&D waste, dirt, asphalt, or concrete rubble, separating recyclables and fines on-site to reduce landfilling. In infrastructure uses (road base, asphalt production), a mobile screen can be moved as needed to produce well-graded aggregates or engineered fill of predictable quality. With heavy-duty tracked frames and on-board washing, Polygonmach's PTS155/185 screens are engineered to operate dependably in the harsh conditions of mining pits or large construction sites, and yet be suited for urban work sites.
Track Mounted Jaw Crushers (PTJ Series)
PTJ series track-mounted jaw crushers are built for primary crushing of abrasive hard material with the benefit of full mobility. Polygonmach offers two jaw models, PTJ106 and the heavier PTJ175, to fit a range of production needs. Both machines have a heavy-duty jaw crusher (deep feed opening and robust crushing jaw) on a sturdy tracked chassis, which enables it to creep into inaccessible or distant areas where fixed crushers cannot be set up. This setup provides amazing flexibility, with contractors able to crush rock, ore, or demolition concrete at the site and move the crusher as the work face changes.
Despite their portability, the PTJ jaw crushers achieve high production. The larger PTJ175 model (with around 1175×800 mm jaw size) has a capacity of around 300 tons per hour throughput in ideal conditions and is thus suitable for high-capacity quarrying or mining operations. The PTJ106 is more compact and hence better adapted to medium-scale applications or limited job sites but can still tackle hard rock and bulk waste efficiently (generally in the order of ~150–200 tph, depending on feed). Both models have steep nip angles and an aggressive crush force for tackling troublesome feed material like basalt, granite, or reinforced concrete. For example, these portable jaw crushers merely fragment large boulders or chunks of C&D material into smaller, manageable sizes for secondary crushing.
Other aspects include vibrating grizzly feeders for removal of fines and regulation of the feed to the crusher for consistent crushing and to protect the jaw from overload. The track mounts provide the plants with a low center of gravity and excellent stability on uneven ground, allowing them to operate safely on slopes or uneven ground where wheeled plants would be unable. Remote control and hydraulic CSS (closed side setting) adjustment are optional for operator convenience, allowing output size to be altered swiftly and the unit to be repositioned quickly. Maintenance is facilitated by built-in access platforms and advanced control systems that monitor performance and alert operators to any issues.
Applications: PTJ track jaw crushers are used by mining and quarrying companies as the first step in the crushing process, which reduces blasted rock to base sizes for conveyor or secondary crusher feed. The track mobility of these jaws makes them able to be moved along a rock face or to other pits, reducing the volume of raw material hauled by truck. Within the construction sector, track-mounted jaws are particularly good at demolition and recycling tasks – they can be brought on-site to crush concrete foundations, building rubble, or asphalt fragments, reclaiming useful aggregates in place. This not only saves waste disposal costs but also produces recycled product that can be re-used in new construction (promoting sustainability). Mobile jaw crushers are also employed by contractors and municipalities for infrastructure development, for example, road base groundwork or railroad ballast, where processing has to occur in more than one location. In total, the PTJ106 and PTJ175 provide dependable heavy-duty crushing performance with the ability to move where it's needed – a synergy that increases efficiency while reducing operational expenditures for material producers.
Track Mounted Impact Crushers (PTI Series)
Polygonmach's PTI series track-mounted impact crushers are high-efficiency mobile plants for flexible crushing tasks, ranging from primary rock crushing to recycling concrete and asphalt. The range includes two base models – PTI110 and PTI113 – that indicate the horizontal impactor size/class, and both can be provided with or without an onboard post-screen. The impact crushers feature a heavy rotor (approximately 1100 mm width on the PTI110, and 1200×1300 mm on PTI113) with blow bars to allow high reduction ratios and good aggregate shapes. These track impactors crush feed material up to medium-hard stone and reinforced concrete, and are therefore ideally matched to work requiring both mobility and effective fragmentation of material (e.g., on-site recycling or secondary quarry crushing).
Although contained in a compact transport package, the PTI crushers have high capacity – for instance, the larger PTI113 will crush about 350 tons per hour of material in concrete recycling or limestone crushing applications. Both units are powered by high-powered engines (~300–408 HP range) and include state-of-the-art hydraulic drives, which ensure efficient crushing and fast response to load changes. Polygonmach supplies every impactor with a variable-speed feeder and pre-screen, which maximizes separation of fines and loads the crusher evenly, maximizing performance and reducing wear. Onboard magnets and dust suppression systems are also featured on the machines, requirements in recycling operations (for extracting rebar/metal and suppressing dust in the vicinity of the job site).
Most significant among these options are the "PS" models: PTI110PS and PTI113PS have a post-screen module and oversize recirculating conveyor installed on the same tracked frame. The closed-circuit design allows the machine to deliver a calibrated final product (for example, a specific aggregate size or asphalt spec material) in one pass. The detachable double-deck screen removes any oversize that is recirculated automatically back to the impact crusher for re-crushing to spec. What is achieved is a highly mobile plant that can replace a larger multi-component system, particularly ideal for small to medium-sized contractors looking to produce saleable aggregates (like 0–25 mm roadbase or 0–3/4\" recycled concrete) directly on site. If the project doesn't require the post-screen, the PTI110 and PTI113 (no PS) offer a lighter weight configuration with quick setup – perfect for primary crushing applications or when coupling with a stand-alone screening plant.
Applications: Concrete and asphalt recycling is a leading application for track-mounted impactors – these machines can be taken to a demolition site or road project and crush reclaimed pavement, concrete slabs, and debris into usable aggregate. The PTI series' ability to handle rebar and steel (with the magnetic separator) makes them well-suited to recycling yards and urban demolition projects. In quarries, a PTI crusher can serve as a mobile primary crusher for limestone or as a secondary crusher following a jaw, especially where a cubical stone shape is required (for example, concrete aggregate production). Their mobility also makes them suitable for pit-run or "crush-and-go" applications, moving to multiple extraction sites. Overall, Polygonmach's track impact crushers provide a versatile, high-production solution for contractors and quarry operators who need to crush a wide variety of materials and value the convenience of a portable, all-in-one crushing plant.
Track Mounted Cone Crushers (PTC Series)
For secondary and tertiary crushing stages where accuracy and high capacity are needed, Polygonmach offers the PTC series track-mounted cone crushers. PTC200 and PTC300 are two models that top this line, both merging proven cone crusher technology with the mobility of a track machine. The PTC300, for example, is based on a 300 HP class cone and can reach throughputs of up to approximately 440 metric tons per hour in favorable conditions. Its smaller brother, the PTC200, is based on a moderately smaller power cone (200 HP range) for situations where a smaller solution is required but with the same high-quality aggregates.
These cone track-mounted plants are designed to produce consistent, well-shaped material (#57 stone, asphalt aggregate, or concrete sand) from hard rock feeds such as granite, basalt, and river gravel. Built with a heavy-duty steel frame and optimal weight distribution (~49+ tons for the PTC300), they ensure stability and low vibration even at high-speed crushing. The crushing chamber is adjusted hydraulically, allowing operators to closely match the output size and gradation. Polygonmach uses user-friendly automation systems on the PTC cones, including touch-screen controls and cone load, motor power, and wear monitoring – which makes peak performance easier and protects the crusher from overloading conditions.
Perhaps one of the most impressive aspects of the PTC series is the advanced hybrid drive system. Power for each module can be provided by its own diesel engine-driven generator or from mains power where available, with significant fuel economy and the potential to operate in emission-regulated areas. The option of engines drive electric motors for the cone and conveyors, so the system has the efficiency of an electric plant and the mobility of a portable plant. The compact travel sizes (about 16.2 × 3.45 × 3.65 m for PTC300 in travel mode) enable the crushers to be transported on a standard low-bed trailer without any special permits. It is fast to set up once on site – the plant can be erected and crushing shortly after arrival, thanks to hydraulically folding conveyors and minimal groundwork needs.
Applications: Track-mounted cones are ideally suited to aggregate production, where they will typically follow a primary crusher and take coarse rock to deliver finished sizes. For instance, in a hard rock quarry, the PTC300 would accept 8–10 inch blasted rock from a jaw crusher and reduce it to 3/4″ or 1/2″ stone in a single pass, with the mobility to move closer to the face as needed. Mine sites use these cones to process ore (iron ore, copper, gold ore) after primary crushing, producing feed for mills or heap leach operations with high accuracy. Contractors like using a mobile cone in highway or infrastructure projects where multiple sites require crushed rock – the track cone can be relocated to each site rather than hauling material from a central fixed plant. Moreover, the hybrid electric alternative renders these units a practical choice for urban work or tunnels, where diesel emission ventilation is a problem or where electricity is readily available. Overall, the PTC200 and PTC300 deliver "stationary plant" performance in a portable design, which offers producers an efficient tool for meeting aggregate spec while being flexible and cost-effective in their operations.
Track Mounted Scalper Screens (PTK Series)
To match the finishing screens, Polygonmach's PTK series track-mounted scalper screens are specially developed for heavy-duty coarse material screening and separation under the most demanding conditions. The two models – PTK144 and PTK156 – are high-capacity mobile scalpers with large double-deck screens (often with heavy-duty punch-plate or grizzly top decks for primary screening). These units excel at processing dense rock, debris-laden dirt, demolition waste, or blasted muck, performing the valuable tasks of fines and contaminant removal before primary crushing or the extraction of usable fill from oversize rock. Built heavy and with high screen vibration intensity, the PTK scalpers can handle bulk material at very high feed rates while resisting impact and abrasion in uses that might overpower a lesser screen.
Built with contractors in mind, the PTK144/156 scalpers feature hydraulic folding conveyors and hopper walls for quick breakdown and setup, allowing the entire unit to fold up for transport. When erected, the conveyors (oversize, midsize, and fines belts) can be hydraulically unfolded and set, and the screen angle can typically be adjusted to control material flow. Wireless remote control operation and PLC control system are standard, making these screens state-of-the-art in user control and safety – operators can start/stop feed or adjust settings from the loader or excavator, increasing convenience and keeping personnel away from the equipment. Of special note, the PTK scalpers possess dual-power capability: they may be powered from the onboard diesel genset or connected to an external electric supply, offering unmatched flexibility and economy (electric mode can drastically reduce fuel consumption). All main drives (screen motors, etc.) are energy-efficient electric motors, and components like screen media are modular and quickly replaceable, minimizing downtime in the field.
Applications: The track scalper screens are used primarily in front-line screening. In a quarry scenario, a PTK156 would be situated at the pit, scalping fines, clay, and small stone from blasted rock, so only oversize, clean rock is fed to the primary crusher – this improves the crusher's performance and creates a cleaner product. On building sites or pipeline work, a mobile scalper can screen excavated soil or gravel, separating out large rocks or breaking up clods, and thus creating spec fill material on site. Recycling operations are also enhanced: for example, in a stack of mixed demolition material, the scalper can remove large chunks of concrete or wood, and screen out earth, leaving a manageable size fraction for the crusher to handle. The PTK machines' ruggedness enables them to screen material like coal, limestone rip-rap, or even contaminated material without excessive wear. Their heavy-duty double-deck design gives several sizes of product in one pass, so one scalper can, for instance, simultaneously produce an oversize for re-crushing and a mid-size product for direct use. Briefly, Polygonmach's PTK track scalpers provide reliable, high-output screening in the toughest conditions – your crushing circuit's "guardians" that increase efficiency and protect downstream equipment by effectively separating material.
Track Mounted VSI Crushers (PTV Series)
In tertiary and quaternary stages of crushing, where fine aggregate and sand production is the priority, Polygonmach's PTV series track-mounted VSI crushers are the tools of choice. VSI (Vertical Shaft Impact) crushers have a high-speed rotor and anvils for rock-on-rock crushing, which yields perfectly shaped, cubical particles needed in modern concrete and asphalt mixes. The PTV track VSI series includes three models – PTV700, PTV800, and PTV900 – to tackle different throughput needs and feed sizes. Each model is a mobile unit that carries a vertical shaft impactor and a feed hopper, discharge conveyor, and integral control system, all on steel tracks for total mobility. They can be small in design (even ideal for urban job sites), but the PTV crushers are loaded with sophisticated technology. They feature Polygonmach's newest "Rockshell 3/5-port" rotor style and Anvil Ring with Open Shoe Table, which together enable efficient, consistent crushing and optimum particle shape. The rotor has different port configurations (3-port or 5-port) to adjust the cascade flow and output fineness, in effect providing some machine adjustment for the material being crushed. Meanwhile, the open table and anvil ring configuration gives a high-speed impact chamber delivering a consistent gradation of sand and fine aggregates to close specifications for concrete sand (e.g. <5 mm) or asphalt screenings. These VSI machines also have variable frequency drives, so the rotor speed can be varied to improve the particle shape or gradation as needed. For maintenance, the VSI’s wear parts (like shoes, anvils) are accessible and can be replaced on-site, and the track frame includes catwalks for safe inspection and servicing.
Applications: Manufactured sand production is a primary use – a PTV series crusher can take crusher dust or small crushed stone and turn it into high-quality sand that has the right shape and granular distribution for use in concrete or asphalt. This is increasingly important with the dwindling natural resources of sand and progressively higher specifications for artificial sands. Track VSIs are used by asphalt plants and contractors to manufacture asphalt sand (often 0–5mm) with very good polish value and adhesive qualities. In concrete aggregate shaping, a VSI may be added after the cone crusher to improve aggregate shape (eliminating flaky particles), which will increase workability of concrete. The track-mounted configuration enables the VSI to be brought to the feed material - for instance, on-site river gravel crushing and shaping at a dam project, or being moved from one concrete plant site to another as needed. Industrial minerals and recycling can also benefit: PTV crushers can be used to crush glass, slag, or even certain ceramics into fine, uniform particles. The PTV700/800/900 machines, by offering a range of capacities and rotor sizes, allow operations to choose the right size of machine – from smaller models for 100-150 tph sand applications up to bigger machines with close to 300 tph in capacity. Along the way, the track mobility and quick setup (often within hours) mean even short-term crushing contracts can be met efficiently without putting in static infrastructure. In effect, Polygonmach's track VSI crushers are the perfect answer for any producer who needs high-quality fine material with the bonus of a mobile alternative, ensuring your end products to be of the highest industry standards.
Track Mounted Stackers (PTT Series)
Rounding off the mobile equipment line are Polygonmach's PTT series track-mounted stackers – track-mounted mobile conveyor systems, which are employed to stockpile bulk materials efficiently in mining, aggregate, and recycling operations. There are three models in the series with different conveyor lengths: PTT60, PTT80, and PTT100, which roughly correspond to 60-foot, 80-foot, and 100-foot long stackers. These track-mounted stackers allow operators to automate the building of piles of crushed stone, sand, gravel, ore, coal, or other bulk materials, reducing the need for loader re-handling and improving site safety and logistics. The mobility on wheels allows these stackers to relocate and circle around the site or follow a mobile crusher/screen, stacking material to high heights and in precise locations that are not possible for wheeled conveyors or fixed stackers.
All PTT stackers feature a heavy-duty lattice conveyor boom with a spacious feed hopper on the tail end and a tracked bogie at the base. They have high capacity (usually capable of 500+ tph transfer rates) and can create huge stockpiles – the PTT100, for instance, can stockpile material up to ~10–12 meters high, in a radial pile tens of thousands of tons of material. Hydraulic slewing and lifting mechanisms allow the operator to vary discharge height and slew (rotate) the conveyor for even material distribution or to shift stockpile positions easily. Many operations pair a track stacker directly with a mobile screen or crusher: the stacker can travel along with material being created, catching the outflow and stacking it efficiently. Additional control options on Polygonmach stackers provide remote control operation (for unit driving and positioning) and emergency stop systems for convenience and safety. Like other Polygonmach track units, the stackers are built for reliability and transportation ease – they can be compacted for transport to the next site.
Uses: Track stackers are used in mining to stockpile ore or waste in a productive fashion – for example, after a primary crusher, a stacker might create a surge pile of crushed ore to feed the processing plant, or stack overburden in a dump. Its tracks allow it to climb rough ground and position where needed, in contrast with fixed conveyors. At aggregate yards and quarries, a PTT stacker takes the crushed/screened aggregate and produces conical or radial stockpiles of various products (aggregate sizes) without loaders having to move material constantly. This not only saves labor and fuel costs but also prevents segregation of the material by forming conical or radial piles in a controlled manner. Mobile track stackers are also well-suited for constructing high volume piles on small footprints, as the stacker can be relocated to stack the pile higher and create more space. At recycling facilities, a stacker can stack shredded or crushed material (for example, wood chips or recycled concrete) for load-out. They are also used in ports or rail yards for holding bulk commodity like coal, gravel, or sand because they can be relocated simply to unload crusher hoppers or feed barges. With the addition of a track stacker, operations benefit from a more continuous flow of material – crushers and screens can run continuously as the stacker loads continuously clear product, and the need for dump trucks or loader haulage is greatly reduced. For any operation seeking to maximize material handling efficiency and reduce cost, Polygonmach's PTT60/80/100 stackers are a sound investment – highly mobile, easy to operate, and capable of creating enormous, well-ordered stockpiles that keep your production moving.
