D. Mixture storage silo: Cubage  2.5 M^3,  below part equipped with material inducing device, discharging outlet equipped with temperature sensor; 

The discharging door structure adopts hydraulic cylinder, hydraulic pump and so on; 

Motor power 2.2kW. Mixture discharging height  2.8m.
E. Advantages
The drying drum is driven by gear-tooth joggle with reliable capability; elevator board chain material 40Cr, hanging hopper material is 65Mn.

6. Asphalt supply system
Components
Asphalt tank: 10 M³, 1 asphalt pump, 1 asphalt pipeline.
The wind drawing fan motor power: 4kw.
Electromagnetism timing motor power : 2.2kW.
Advantages
The asphalt tank burning coal or firewood, using circle hot wind pipeline to heat the asphalt. big capasity, relirable working performance,long working life.

7. Electric control system
A.The figure dimension 2.2x2.2x2.5m; Copy container structure, the walls, door and windows are made of colorized steel plate. Pleasing shape, good seal; easy to hoist and transport.
B.Box type control cabinet, main electric parts are Zhengtai, Schneider, which has interlock and two-grade protection; 

C.The operation panel equipped with manual operation device, digital indicator for main motor, mixture temperature,  cold aggregate, fuel and asphalt.
