LB asphalt batching plant is a stationary asphalt mixing plant mainly consiting of cold aggregate supply system, drum dryer, burning system, hot aggregate elevator, vibrating screen, weighing system, mixing tower, dust collecting system, filler supply system, bitumen supply system, electronic control system, finished asphalt storage bin. The asphalt plant adopts modular design, easy installation and maintenance, fast removal and transportation. It is mainly used for the construction of highways, highways, municipal roads, airports and ports.

1. Modular design and integrity steel base, reasonable layout, demolition, transportation and installation faster and easier.
2. Superior drying drum plate design, and independent research and development of advanced combustion heating technology to improve efficiency, reduce energy consumption.
3. Plus high hot aggregate bin design to increase the stock of hot aggregate storage, to increase producing capacity.
4. Automatic/manual control system with failure self-diagnosis program, simple and safe.
5. Core components adopt international famous brand products, such as Siemens electrical components, EBICO burners, Switzerland METTLER TOLEDO weighing sensor, etc., reduces the failure rate and prolong its service life.


Cold Aggregate Feeding System

All silos are equipped with belt feeders controlled with the frequency converting motor, which can realize single silo adjusting and entire silos proportioning adjusting, ensures measuring precision and low energy consumption. A vibrator on sand bin wall ensures feeding reliability. Tail and directive wheels are specially designed self-cleaning type. The rubber is covered on the surfaces of driving wheels to prevent wheel-spin.

- The belt feeder use frequency conversion speed control, speed adjust rang is wide, high working efficiency.

- Every hopper discharge gate have material shortage alarming device, if material shortage or material arching, it will alarm automatically.

- On the sand bin, there is vibrator, so it can guarantee normal working.

- There is isolation screen on top of cold bin, so can avoid large material input.

- The conveyor belt use circular belt without joint, steady running and long performance life.

- At the input port of feeding belt conveyor, there is one simple screen can avoid big material input which can enhance hot efficiency and make sure the drying drum, hot aggregate elevator and vibration screen work reliability.

Drying System

Drying system is the key part of the whole equipment, its drying ability affects the mixing capacity directly, the aggregate temperature can directly affect the finished product temperature, the drying efficiency influence the fuel consumption greatly. Therefore the design of structure rationality is very important.

Drying system includes drying cylinder, main burner and fuel feeding sytem. There are four gear reducers connected to four friction wheels by cross head univesal shaft to drive the drier, with the advantages of installation deviation compensation, high driving efficiency, stable dricing and so on. The external insulating  layer and the specially designed blades ensure that maximum heat is transfered to the aggregate. The thermal efficiency is high and the exhaust temperature at the end of the cylinder is below 120 degree. The world advanced burner is adopted. The usable fuel includes diesel, heavy oil, residual oil, gas, coal and so on. Another alternative burner developed by ourselves has the same performance with 8:1 adjusting rate, economical efficiency and adaptability with the former. All components of the advanced infared temperature measuring and controlling syystem are imported from famous overseascompanies to ensure the temperature control accuracy and reliability.


Dust Collecting System

German techniques are adopted to combine the two-level dust collectors in order to save the floor space specially designed first-stage inertial dust separator has the simpler structure and the higher efficiency. The bag dust collector is designed  with the flat bags. The structure is compact an dthe dust can be easily cleaned out. The filter bags are made of the fire-resistant material, which can satisfy the requirement of environmental protection standard.

The high-low temperature alarm device and the automatic flame out device for too high temperature are designed in the control system. The unique designed blowback system and other special  design ensure the dust removal system to work reliable.
