Stationary Batch Type Hot Mix Asphalt (HMA)

The stationary batch type hot mix asphalt (HMA) plant is a significant component in the construction industry, especially for road construction and maintenance projects. This type of plant is designed to produce hot mix asphalt in batches, allowing for precise control over the mixture composition and quality. Each batch can be tailored to meet specific requirements, such as the aggregate size, the type of bitumen used, and any additives that may be necessary. This customization capability makes stationary batch type plants highly versatile and suited to projects that require a variety of asphalt mixes. The plant consists of several key components, including aggregate supply system, drying drum, batching tower (which houses the mixing unit), and storage silos for the finished product. Operating in a fixed location, these plants are typically preferred for long-term projects or in scenarios where the same mix formula needs to be produced consistently over time.

Unlike continuous mixing plants, the batch processing in a stationary batch type HMA plant ensures that each batch can be produced with a high level of accuracy and quality control. This is particularly important for projects with tight specifications, such as airport runways, major highways, or urban roads. The process begins with the metered introduction of aggregate into the dryer drum, where it is heated and dried. The heated aggregate then moves to the mixing tower, where it is combined with bitumen and any other additives. The mixture is thoroughly blended to produce the final asphalt mix, which is then stored in silos until it is needed for use. This methodical approach to asphalt production allows for adjustments between batches, making it easier to address any issues and ensure the final product meets all necessary standards. The stationary batch type hot mix asphalt plant's ability to deliver high-quality, customized asphalt mix makes it a valuable asset for any road construction project requiring precise and consistent results.

Mobile Hot Mix Type Asphalt Plants

Polygonmach's Mobile hot mix type asphalt plants are modern facilities that are frequently preferred in road construction projects that require high efficiency and flexibility. Basically, these facilities produce asphalt cooked at high temperatures by mixing raw materials (sand, gravel and bitumen) in certain proportions. The most important feature of mobile hot mix facilities is that they can be easily moved without being tied to a fixed location. In this way, they can be quickly installed and used in different projects and construction sites depending on the requirements of the job. The portability feature allows changing the optimal location of the facility at different stages of the project, which reduces logistics costs and saves time.

Mobile hot mix type asphalt plants are produced in various capacities and features, thus offering solutions suitable for the needs of projects of different scales. Equipped with modern control systems, these facilities constantly monitor and adjust the quality of the mixture, ensuring that the final product complies with standards. They also offer more sustainable solutions thanks to improved filtration and emission control systems to reduce environmental impacts. With their short installation time, ease of use and high efficiency, mobile hot mix asphalt plants are an important part of today's road construction projects.

Continuous Type Asphalt Drum Mix Plants

The Continuous type asphalt drum mix plants are streamlined facilities designed for the efficient and continuous production of asphalt mix, making them ideal for projects requiring a large volume of asphalt without significant variations in the mix design. Unlike batch type plants that produce asphalt in batches, drum mix plants operate by continuously mixing the aggregate, bitumen, and any additives in a rotary drum. This process starts with the cold feed of aggregates into the drum, where they are heated and mixed with bitumen and possibly reclaimed asphalt pavement (RAP) materials in a single pass. The simplicity of this design minimizes interruptions in production, offering a steady and uninterrupted supply of hot mix asphalt (HMA). This continuous flow process results in a more uniform product, as the materials are constantly moving, which reduces the risk of segregation and ensures a consistent quality of the asphalt mix.

One of the key advantages of continuous type asphalt drum mix plants is their operational efficiency and reduced maintenance compared to batch type plants. Since the mixing of components occurs in one continuous process, there are fewer moving parts, which translates to less wear and tear and ultimately lower operational costs. Additionally, these plants are often more compact and require less space, making them easier to set up and relocate, if necessary. The continuous mixing process also allows for greater flexibility with materials and mix designs, which can be adjusted on the fly to meet specific project requirements. Environmental considerations are taken into account with modern drum mix plants as well, featuring advanced dust collection systems and emissions controls to meet regulatory standards. Their efficiency, coupled with lower operational costs and environmental compliance, makes continuous type asphalt drum mix plants a favored choice for large-scale road construction and maintenance projects.

Bitumen Emulsion Plants

Polygonmach's Bitumen emulsion plants are specialized facilities designed for the production of bitumen emulsion, a mixture of bitumen and water with the addition of an emulsifying agent. These plants blend these components under controlled conditions to produce a homogenous emulsified product that is used in road construction and maintenance, as well as in other civil engineering applications. The main advantage of bitumen emulsions is their ability to be applied at lower temperatures compared to hot bitumen, making them an environmentally friendlier and safer alternative. This characteristic not only reduces energy consumption but also minimizes the risk of burns to workers involved in its application.

The process within a bitumen emulsion plant involves the accurate dosing and mixing of specific quantities of bitumen, water, and an emulsifier. This process is highly reliant on sophisticated control systems to ensure the stability and consistency of the final product. Bitumen emulsions are categorized into different types, including cationic, anionic, and non-ionic, depending on the nature of the emulsifier used. Each type has distinct properties and applications, with cationic emulsions being the most common type used in road applications due to their superior adhesion properties. Modern bitumen emulsion plants are capable of producing a wide range of emulsions, meeting various specifications for different applications, ensuring versatility and efficiency in road construction and maintenance projects.

Mechanical Stabilization Plants

Mechanical stabilization plants are industrial setups crucial for the process of enhancing the physical properties of soil or aggregate mixtures, primarily used in the construction of foundations, road bases, and embankments. The core principle behind mechanical stabilization involves the mixing and compaction of soils with or without the addition of aggregates, to improve their bearing capacity, density, and overall stability. These plants are equipped with sophisticated machinery such as mixers, crushers, and pugmills, which facilitate the thorough blending and consistent treatment of the material. By adjusting the soil's physical characteristics, such as its gradation, texture, and compaction, the mechanical stabilization technique ensures the soil mixture achieves the desired strength and durability required for various construction projects.

Mechanical stabilization plants play a pivotal role in the construction industry by making use of locally available materials and transforming them into a more stable and reliable construction material. This process not only optimizes the strength and longevity of the construction foundation but also significantly reduces the environmental impact by minimizing the need for transporting materials over long distances. Furthermore, these plants are designed to handle a wide variety of soils and can be adjusted to meet the specific needs of each project, thereby providing a versatile and cost-effective solution for improving ground conditions. The end product of a mechanical stabilization plant, a uniformly mixed and compacted material, is key to ensuring that infrastructure projects are built on a solid and stable base, leading to safer and longer-lasting structures.

Bitumen Barrel-Drum Heaters Decanters

Polygonmach also offers Bitumen barrel-drum heaters and decanters are specialized equipment used in the construction industry, particularly in road construction and maintenance, for efficiently melting bitumen that is stored and transported in barrels or drums. Given the high melting point of bitumen, these machines play a crucial role in preparing the bitumen for use by heating it to a workable temperature. The process involves the gradual heating of bitumen barrels or drums using either direct or indirect heating methods. Direct heating may involve flame contact with the container, whereas indirect heating uses a thermal oil or similar heat transfer fluid to warm up the bitumen without direct flame contact, thus minimizing the risk of overheating or compromising the bitumen’s quality.

These systems are designed to ensure a uniform and controlled heating process, preventing the degradation of the bitumen’s properties. Bitumen decanters, in particular, are highly efficient, facilitating the transfer of melted bitumen from barrels or drums into hot mix plant tanks or directly into trucks or sprayers for application. This equipment significantly enhances operational efficiency by reducing the time and labor involved in handling and preparing bulk bitumen. Moreover, the use of barrel-drum heaters and decanters minimizes wastage and maximizes safety on site by containing the bitumen within a controlled environment, reducing the exposure to hot materials and fumes. With the increasing demand for efficient road construction and maintenance solutions, these systems have become indispensable in ensuring the continuous availability of ready-to-use bitumen in a safe and efficient manner.

Polymer Modified Bitumen (PMB) Plants

Finally, Polygonmach's Polymer modified bitumen (PMB) plants are specialized facilities designed for the production of an enhanced form of bitumen, which is mixed with various polymers to improve its physical properties. The primary aim of these plants is to blend bitumen with polymers such as styrene-butadiene-styrene (SBS), ethylene-vinyl acetate (EVA), and others, to produce a bitumen that exhibits superior performance characteristics. These characteristics include improved elasticity, greater resistance to deformation, better durability against weathering, and increased resistance to temperature fluctuations. PMB is extensively used in road construction, particularly for surfaces subject to extreme weather conditions or heavy traffic, as it can significantly prolong the lifespan of roadways by preventing common issues like rutting and cracking.

The production process in a PMB plant involves several critical steps, starting with the heating of the base bitumen to a suitable temperature that allows for the efficient mixing with the polymer. This mixture is then agitated thoroughly in a high-shear mill to ensure that the polymer is evenly dispersed throughout the bitumen, creating a homogenous blend. After the mixing process, the polymer-modified bitumen needs to be stored at a specific temperature to maintain its enhanced properties before it can be transported to construction sites. Modern PMB plants are equipped with advanced control systems to accurately manage the production parameters, ensuring consistent quality of the final product. These facilities also incorporate safety and environmental protection measures, such as fume recovery systems, to minimize the impact of the production process on the environment and worker health. With the growing demand for more durable and longer-lasting road surfaces, the role of polymer modified bitumen plants in the construction industry continues to expand.
