Product Introduction of LQC80 Asphalt Concrete Mixing Station

1)Cold Feed System

Frequency-controlled belt feeder allows for independent and automatic adjustment of feed speed as per production and proportioning requirement.
Modular design allows for various types of hopper combinations.

2)Highly Efficient Screening Unit
Developed and manufactured with techniques originated from Europe. Adequate screening area and optimum match between vibration angle and inclination angle enable the vibration screen to meet the conditions for strict component proportioning and high screening efficiency. Amplitude and centrifugal force of the vibrating screen are adjustable to adapt to various proportioning. Screening efficiency(rated) ≥95%;messing rate(nominal) <5%.

3)Drying and heating system
Optimized flights and lifter design allows system to achieve a more uniform heating.
Optional burners are available to operate on diesel oil, heavy oil, residual oil, natural gas, coal, etc.

4)Hot Mineral Silo
Large capacity hot mineral silo effectively ensures ongoing production of the asphalt mixing plant.

5)Weighing Module
The weighing system with the weigh hopper resting on load cells maintains good weighing balance, thereby effectively resolving the problem of deviation of center of gravity.

6)Top Quality Mixing Module
Pressurized bitumen is atomized via a multi-hole spray bar and filler is spirally distributed or discharged in axial direction of the mixer. Filler and asphalt are evenly distributed, thereby greatly reducing dry mixing times . 
Twin shaft compulsory mixer, driven by geared motor units via equal gear wheels. The special mixer design featuring a double paddle arm pattern for powerful and intensive stirring behavior, with low rotation speed and large capacity, effectively avoids segregation and secondary gradation changes during mixing ensuring unrivalled mixing quality.
Mixer shafts with labyrinth seals to ensure zero leakage.
Skip Unit and Mixed Material Storage

7)Separated Silo Pattern
Automatic skip unit features frequency controlled gear motors and high speed pulse encoder giving precise control of skip speed and positioning. This total control of the skip allows it to be smoothly accelerated along the track and then slowed as it approaches the required station. Independent pneumatically operated brake ensures reliable braking and accurate positioning. 
The skip features a rotary unpowered soft touch opening discharge door offering the advantages of safe operation, low impact, thorough discharging and no spillage of material, as compared to traditional lever impingement opening type skip door.
The special interior design of the storage silo could effectively stop stored materials from segregating.

8)Integrated Silo Pattern
Integrated silo pattern offers the advantages of low power consumption, low failure rates, low emissions, economic on space, little segregation, low heat loss, easy extensions, etc.

9)Bitumen Storage and Heating System
Full-function bitumen tank equipped with mixer, level indicator, and automatic temperature control valve. 
Optional independent discharge system permits on-line discharge of thermal oil without affecting plant operation. 
Number of bitumen tanks and layout as per customer specifications

10)Dust Collection System
Two-stage dust collection system; initial separator(gravitycyclone) and bag filter, which has been recognized as one of the most efficient and reliable forms of dry dust collection with guaranteed emission levels of≤20mgn.m3. 
Optional reclaimed filler silo and wet collectors (venturi scrubbers) minimize dust emission and solve the problem of transportation.

11)Control System
Two high performance industrial computers employing the latest hardware technology and software packages link together several groups of function modules to form one integral site network for automatic production control and management.
The two computers are designed to work in parallel for reliable plant control and higher information processing capacity.
