Cutting-Edge Machines for a New Era of Mining: Polygonmach’s Engineering Powerhouse

Mining operations rely on a complete processing line – from crushing and screening to conveying, washing, drying, stacking, and ore enrichment – to efficiently convert run-of-mine ore into marketable materials. Polygonmach provides a full suite of high-performance equipment for each of these stages, ensuring reliable throughput and product quality. The sections below explain each equipment category, citing industry references, and demonstrate how Polygonmach machines meet common mining requirements.

Crushing Equipment

Crushers are the first step in reducing run-of-mine (ROM) rock into smaller sizes for processing. Polygonmach’s crushing line includes jaw crushers, cone crushers, and impact crushers. Jaw crushers (for example, a large-feed Polygonmach PJC jaw crusher) have very big feed openings (often 1–1.5 m) and heavy-duty toggle plates, so they can bite large boulders and produce hundreds of tonnes per hour of crushed stone. Cone crushers (secondary/tertiary crushers) and impact crushers (used for softer ores) further reduce rock to specified sizes. Efficient crushing maximizes throughput while producing uniform output – essential for downstream handling. For example, a typical heavy-duty jaw crusher with a ~1.2×0.8 m feed opening can crush up to 600–800 tph of hard rock in primary service. Polygonmach crushers are engineered for long service life and easy maintenance, helping mining companies achieve consistent crushing performance at high tonnages.

Screening Equipment

After crushing, vibrating screens separate the crushed ore into different size fractions. Polygonmach vibrating screens (inclined or horizontal) have rugged decks that sort material by mesh size, producing multiple product streams (e.g. fines, mid-size, coarse). Screening is pivotal in a processing circuit: it ensures only appropriately sized material advances to each stage, and fines are removed early. Polygonmach screens come in two- or three-deck models and can handle hundreds of tonnes per hour. Properly sized screens improve overall plant efficiency by minimizing oversize recirculation and ensuring the crushing and washing units see the correct feed. In practice, a medium-size screen might have a screening area of ~10×3 m and process ~400–500 tph, grading materials for further crushing or final products.

Conveying Equipment

Belt conveyors and feeders move material continuously through the plant. Polygonmach offers a full range of conveyors (belt, overland, telescopic, screw, bucket elevators) that transfer ore between crushers, screens, washers, stockpiles, and mills. As one industry guide notes, conveying equipment “transports bulk material through the processing facility and throughout the operation,” and can take many forms (belt conveyors, pneumatic conveyors, chain conveyors, etc.). Polygonmach belt conveyors (up to 1000 mm wide, several tens of metres long) can carry thousands of tonnes per hour, providing a constant feed to crushers or stockpiles. Feed hoppers and vibratory feeders (also from Polygonmach) regulate the flow into crushers. Conveyors and feeders eliminate manual handling, reduce bottlenecks, and ensure plant throughput meets targets.

Washing Equipment

In many minerals operations (e.g. sand/gravel or mineral sands), washing machines are used to clean the ore by removing clay, silt and impurities. Polygonmach washing units (such as sand wash plants, log washers or screw washers) scrub and rinse aggregates to specifications. As explained by Eastman Crushing, sand-washing plants combine crushers, screens and washers so that material meeting spec is sent to the washer for cleaning. The water-washing step “is mainly used to clean various sand and gravel dust, stones, and other impurities in river sand, ground sand, weathered sand, etc.”. Polygonmach sand washers can handle tens to hundreds of tonnes per hour, stripping clays and fines to improve product quality. Washed material exits clean, ready for sale or final processing. By removing unwanted dust and clays, Polygonmach washing systems produce premium-quality aggregates and ores that meet customer specifications.

Drying Equipment

Many ore-processing flowsheets include a drying stage after beneficiation or washing. Polygonmach provides industrial rotary dryers designed for minerals. Drying raw ore reduces moisture, which has several benefits: it cuts transportation costs by not hauling water weight, and it minimizes buildup in bins and conveyors. In fact, experts note that drying ore “makes transportation much more economic by removing the bulk of the moisture… so producers are not paying to transport water weight”. Polygonmach rotary dryers are built for high throughput and durability (thick steel liners, heavy-duty shafts) to meet mining demands. Industry sources confirm that “rotary dryers are the industrial dryer of choice for mineral drying applications,” due to their rugged design and ability to handle abrasive materials. A typical Polygonmach rotary dryer (e.g. 3 m diameter ×15 m long) might dry 30–100 tph of ore, lowering moisture to <1–2% before final crushing or pelletizing.

Stacking Equipment

Once material is processed, stackers (stockpiling conveyors) are used to build large piles efficiently. Polygonmach offers radial stacker conveyors and telescoping stackers that can deposit material on the fly. A radial stacker is essentially a long conveyor mounted on a rotating base, so it can sweep out an arc and form wide, high stockpiles. As one conveyor supplier describes, a radial stacker “can deposit material at a rate of up to 1,200 tons of material per hour” and is “more efficient than wheel loaders or screw conveyors” for stockpiling. Polygonmach radial stackers (e.g. 25–35 m reach) move ore up to 20° angles, creating large cones of crushed ore or aggregates. These stackers reduce dust (by controlled drop height) and eliminate the need to re-position heavy equipment as a pile grows. In practice, a typical Polygonmach stacker with a 30 m boom can stack 800–1200 tph of ore, greatly improving yard management and safety.

Enrichment (Beneficiation) Equipment

The final stage, ore enrichment (beneficiation), upgrades ore by separating valuable minerals from waste (gangue). Polygonmach provides gravity concentrators (spirals, shaking tables), flotation cells, and magnetic separators depending on the ore. In general, beneficiation “is the process of separating valuable ore from waste using methods like gravity, flotation, or magnetic separation”. For example, spiral concentrators can separate heavy mineral sand (ilmenite, zircon) by gravity flow, while flotation machines recover copper or gold by surface chemistry. By upgrading the ore, Polygonmach enrichment systems “reduce environmental impact and costs related to handling, transportation, and extraction”. A gravity concentrator might process a slurry of 10–30 t/h, yielding a high-grade concentrate and reducing the tonnage for further grinding. This final polishing step is crucial for maximizing yield and ensuring raw materials meet quality targets.
