Main Features

1. Modular design, compact structure
①. Aggregates elevator is integrated in the mixing tower, making it easy for installation, transportation and relocation;
②. The structure design of our asphalt plant fits container transportation standards, so it greatly reduces the transportation cost and risk, suitable for exportation;
③. Compared with side type product silo, the bottom type product silo makes the installation more convenient and shrinks the covering area. Also it reduces the failure rate because it doesn't need larry or rail.
2. Environmental friendly, qualified for European standards
①. Adopts optimized dual dust collecting system (primary volute dust collector + Secondary baghouse collector). Efficient pulsating dust-cleaning design, advanced waste powder wet-processing system and negative-pressure system of the main building ensure that the dust emission is under 20mg/m³;
②. Aggregate conveyor is protected by dustproof cover to make the dust leakage at lowest level.
3. Efficient and beneficial drying system
①. Latest burning control method with higher precision of temperature control and better combustion effect perfectly reduces the fuel consumption rate. The blade of drying drum is optimized;
②. The drying system works concordantly with the dust collecting system with higher thermal efficiency.
4. Super mixing ability and stable performance
①. The mixer has powerful overload mixing ability, and its mixing performance is so stable that it vastly decreases the amount of unqualified products;
②. Special made mixing blades plus simple and efficient driving mode make the mixing more convenient, efficient and reliable;
③. Double horizontal shaft structure can mix the aggregates evenly and sufficiently;
④. Bitumen sprayer can make use of every bitumen drop by spraying them evenly, in order to save the cost.
5. More functional and reliable control system
①. Control system adopts both auto and semi-auto control methods. When the PC fails, it's handy to control it manually by simply pressing buttons;
②. To keep safety, the control room is equipped with monitoring system, so the operator can observe the working situation of each key component.
6. More precise and trustworthy weighing system
①. Adopts world famous weighing system, it's more stable and precise;
②. The accuracy error of aggregate weighing is below 0.5%, and the accuracy error of bitumen and filler weighing is below 0.25%. Precise weighing guarantees the quality of final product, on the other hand, it saves the material cost for client.
7. Intelligent and simplified maintenance
①. Driving units adopt self-lubrication device, which saves labor and time cost;
②. Elevator uses double plate link chains design, which extends the elevator's service life, increases the stability, and reduces maintain frequency.
8. Safer and thoughtful facilities.
Maintenance catwalk and protective handrail are more thoughtfully designed to keep safe, for example, the handrail is made of plastics sprayed embossing steel pipes, so that it's easier to hold, and the foot plate employs hot galvanized grid plate which is anti-rust, anti-dust and anti-slip. Both of these details make the machinery more aesthetic.
9. Cost saving and benefit increasing
Super low fuel consumption, precise weighing system and durable quick-wear parts & wear-resistant parts, vastly reduces clients' cost and maximizes their benefit.

Detailed Information
