Characteristics of asphalt mixing plant

Characteristics of asphalt mixing plant

1. high efficiency

Company production of asphalt mixture mixing equipment, production capacity from 80 to 400 tons per hour, equipment machine adopts modular design, convenient installation and maintenance, moving and fast transportation.

2.stability

The whole equipment can be manual, semi-automatic and fully automatic control. These controls are done by PC/PLC for industrial use. Formula inputs, automatic fall correction, asphalt-stone ratio dynamic tracking, automatic fault diagnosis and alarm system and real time print functions.

3. environmental protection

Inertial + pulse bag dust collector to ensure that strict environmental standards, recycling of dust, noise and soot emission concentration within the national industry standard, applicable to urban and field construction.

4. energy-saving

Total installed power low fuel consumption per ton of mix is less than 6.5kg, save energy and create significant economic benefits for the user.

5. mixing system

Each silo uses the frequency conversion velocity modulation motor belt feeder dosing, use set-hard surface reducer, compact structure. Special folder materials wear-resistant design with wear-resistant rib belts, safety, reliability and long life. Has a broken alarm system.

6. aggregate heating and drying system

Drum drive with four motors and hard surface reducer associated with four supporting wheels, friction drum work. Compact structure, high efficiency, stable transmission. Drum sequence distribution in various aggregates and fire heat exchange stock Guide, achieving full heat exchange in the aggregate on the drum. Medium atomization burner can burn diesel fuel, heavy oils and Residua. Using compressed air mixed with fuel atomization, able to adapt liquidity than less fuel. Turndown ratio is 10:1. Burning appliances for energy-saving, low-noise ratio characteristics of automatic control.

7. dust removal system

Dust removal system using Germany technology level gravity filter, bag-type dust collector II merged into one, saving covering an area of. United States filter bags made of DuPont NOMEX material, dust concentration is less than 25mg/Nm3. System with over-temperature protection system.

8. the mixing Tower

Using Germany technology for dual-axis linear vibration vibration sieve sieve. Dual-axis vibration sieve outside bearings with oil lubrication model of European technology, maintenance is very convenient. Rapid hook spring tensioning the screen fixed, make screen changes quickly and easily. Insulation heat silo with insulation system, stone way stone said at the beginning of a second weighing precision, combined with automatic error correction controls effectively reduce splash splashing material difference. On large-tonnage have even adopted a pair of scales and measure of aggregate, not only ensures the accuracy and improve efficiency. Blender using European technology, dual hard surface reducer motor, gear synchronous. Scale weighing sensor for the import sensor, high weighing accuracy, can meet the requirements of any highway. Rotary unloading door is steered by two-cylinder, feeding time is short, good sealing effect. Plate and blades are made of high-strength wear-resisting cast iron, life of up to 105 batches stir.

9. the finished material storage systems

Mount with bottom and side of the finished material storage system for users to choose. Bottom-mounted storage system consists of a storage bin, waste bin and haul cars or directing bodies, compact structure, covering an area of small, energy-saving. Side-mounted storage system by upgrading tracks, lifting trucks, waste bin and the composition of finished material storage hopper. Using inverter, encoder and proximity switch control, winch drive motor adopts the forced air cooling and variable frequency control. 100mm silo wall thermal insulation rock wool, pneumatic unloading doors with electro-heating boiler with thermic oil equipment ensure the switch easily.

10. control systems

Complete mixing equipment control system hardware section contains a control room, PC Console, Germany SIEMENS PLC control cabinets of the component, drag electrical Cabinet Group, power cables and accessories, control cables and accessories, such as air conditioning; software includes bet heavy equipment of asphalt mixture production process: control software unit. The control technology based on Germany SIEMENS PLC technology based on asphalt mixture production process can realize the automatic control of the whole process, semi-automatic control and manual control. Can be produced in strict accordance with construction formula requirements, animation process. All parameters to be set and modified by computer to complete. Formula entered storage, splash-automatic error correction, adjustment, calibration, asphalt-stone ratio dynamic tracking, automatic fault diagnosis, automatic alarm, report printing and storage capabilities.
