What is Asphalt and Bitumen Plants?
It synthesizes information from leading industry research and global best practices to inform polygonmachine’s continued leadership in delivering high-quality, efficient, and sustainable asphalt production solutions. Key findings highlight the critical role of precise bitumen-aggregate control, the distinct advantages of stationary, mobile, and continuous plant types for varied project scales, and the paramount importance of integrated emission control and carbon footprint reduction technologies.
Bitumen, a versatile construction material, is primarily derived from petroleum, characterized by its sticky, highly viscous, semi-solid or liquid form, and black color. Its complex composition includes hydrocarbons like asphaltenes and resins, with minor quantities of sulfur, nitrogen, oxygen, and various metals. This unique chemical makeup grants bitumen its distinctive properties crucial for various applications.
Naturally occurring bitumen deposits are formed from prehistoric microscopic algae and other small organisms that underwent transformation through intense heat and pressure while entombed within the Earth’s surface for eons. Alternatively, refined bitumen is a dense byproduct obtained during the distillation of crude oil, with the resultant material being identical regardless of its natural or refined origin.
The essential properties of bitumen include its long-lasting nature, ability to repel water, strong adhesive qualities, pliability, and capability to withstand various temperatures. These characteristics make it an indispensable material for road paving, where it serves as a key component for surfacing roads, and as an effective waterproofing agent, sealing buildings from moisture penetration. The adhesive quality, in particular, allows roadways to withstand significant traffic loads and extreme weather conditions, maintaining cohesion over time.
Stationary Batch Asphalt Plants
Stationary batch asphalt plants are designed for large-scale, long-term projects, providing consistent, high-quality asphalt for extensive production needs. These plants produce hot mix asphalt by precisely mixing various sizes of aggregate, filler, and bitumen in discrete batches, typically within a short cycle of 40-50 seconds. This intermittent process allows for meticulous control over the composition of each batch, ensuring high-quality and consistent output.
Stationary batch plants, exemplified by various Polygonmachine Series models, offer a wide range of production capacities, typically from 40 tons per hour (t/h) up to 400 t/h. The mixing cycle is consistently around 45 seconds for all models, ensuring rapid production. Asphalt temperature is precisely maintained between 140-180 ℃ during the mixing process
For instance, cold aggregate hoppers can range from 4×4.5m³ for smaller models to 6x15m³ for the largest PBA400. Dryer sizes vary from φ1.2m×5.2m to φ2.8m×10.2m, accommodating different production volumes. Mixer capacities typically range from 500kg to 4000kg per batch. Dust filter areas are substantial, ranging from 230m² to 1350m², reflecting the robust emission control capabilities. Total power requirements for these plants span from 170kW to 865kW, depending on their capacity and configuration. These plants are designed for stable and reliable continuous production at a single site, making them ideal for long-term projects.
Stationary asphalt batch plants are ideally suited for large-scale, long-term infrastructure projects where consistent, high-quality asphalt production is paramount. These applications include the construction of extensive highways, major bridges, urban road networks, industrial parks, and airport runways. Their capability to produce high-grade, consistent mixes makes them particularly suitable for projects with stringent quality requirements.
Mobile Batch Asphalt Plants
Mobile batch asphalt plants are engineered for exceptional mobility and ease of installation, making them highly adaptable for projects requiring frequent relocation or those situated in remote areas. This design philosophy caters to the dynamic nature of many construction projects, where rapid deployment and minimal site infrastructure are critical.
A defining characteristic of mobile batch plants is their fully integrated modular design. Main components are built into mobile chassis, which are designed to conform to international land transportation requirements. This modularity means that only prime movers are needed for quick mobilization and demobilization, significantly reducing logistical complexities and costs. Setup and dismantling are remarkably faster compared to traditional stationary plants, as they do not require heavy cranes or extensive concrete foundations. To ensure immediate operational readiness, these plants are prewired with quick-couple cables and rigorously tested before shipment, enabling true plug-and-play functionality upon arrival at the job site.
Capacities for mobile batch plants typically range from 40 t/h to 160 t/h, as exemplified by series such as the Polygonmachine MBA. Specific models include the MBA (40-60 t/h capacity, 1150 kg batch size), MBA (100-120 t/h capacity, 1500 kg batch size), and MBA(140-160 t/h capacity, 2000 kg batch size). These capacities are generally based on standard plant performance with 3% moisture content in the aggregates.
Mobile batch asphalt plants are ideally suited for short-term projects, projects in remote locations, and those requiring high-specification mixes, such as airport contracts, where rapid deployment and minimal site infrastructure are crucial. Their ability to quickly set up and dismantle makes them invaluable for projects with tight deadlines or shifting geographical needs.
Continuous Type Asphalt Plants (Drum Mix)
Continuous asphalt plants, often referred to as drum mix plants, represent a distinct category in asphalt production, characterized by their uninterrupted flow of material processing. Unlike batch plants that produce asphalt in discrete batches, continuous plants constantly mix ingredients within a rotating drum, ensuring a steady output.
A critical distinction within continuous plants lies in their flow configuration, which significantly impacts their efficiency and product quality:
Parallel Flow: In this configuration, the aggregate flow direction is consistent with the burner flame. Both drying of aggregates and mixing of the asphalt mixture occur in the same drum. Dust collection is typically conducted after the mixing process, which can lead to a lower quality asphalt mix due to the presence of dust during mixing and potential damage to the mixture from direct flame contact, sometimes causing the asphalt to burn. This also means the temperature of hot aggregates cannot be measured separately.
Counterflow: This advanced configuration features an aggregate flow direction opposite to the burner flame. This design allows for more even heating, higher heat utilization, and consequently, less fuel consumption. Crucially, the drying of aggregates and the mixing of the mixture occur in separate drums. Dust collection is performed before aggregate drying, ensuring no dust enters the mixing drum, which results in a premium quality asphalt mix. Furthermore, since heating and mixing are carried out in separate drums, the burner flame does not contact the asphalt, other liquids, or additives, preventing the asphalt from burning and preserving mixture quality.
Continuous asphalt plants are known for their high production capacities, ranging widely from 40 tph up to 160 tph. Specific models, such as those offered by Polygonmachine, provide capacities from 40-60 tph up to 140-160 tph. Some cutting-edge designs, such as the Polygonmachine MCA , aim to combine the advantages of both batch and continuous plants, offering high production output alongside recipe flexibility.
