160Tph 2000 model asphalt mixing plant with 30ton bitumen tank

Working condition of asphalt plant:

1, Moisturecontent of aggregate ≤5%
2, Ambient temperature +0+50
3, Height above sea level ≤1000m
4, Average density of raw aggregate is 1650kg/m3
5, Value of heat for fuel≥10000kacl/kg
6, Residual humidity of asphalt mixture≤0.3%
7, Max diameter of aggregate is 40mm
8, 3mm aggregate screening efficiency≤35%
9, Production contains 5~10% filler and asphalt
10, The aggregate should be in normal shape and should not have a lot of holes or water suction.
The productivity fluctuates in scope of ±10% due to conditions of surrounding environment and material parameters.

Function of control system

control system

The system is composed of upward control computer unit (industrial control computer) and downward programming controller (PLC), weighing meter, weighing sensor, frequency converter and low voltage components, and also equipped with keyboard, mouse, monitor and printer, etc. Each unit uses Ethernet terminal port to communicate.

On basis of MCGS (Configuration Software), control system adopts special control software developed specially for asphalt mixing equipment, which can monitor overall running condition from time to time and display on screen in dynamic mode, at the bottom of screen there is formula control icon and prompt line.

The system can automatically finish state control of each work link, namely all control functions required by equipments such as auto batching, over impulse (difference of level) compensation, failure alarm, report form storage and printing.

 Achieve soft interface and powerful human-machine dialogue function.

 Response working state of all mixing devices in real time.

 Special cold material hopper auto compounding function.

 Accurate PID temperature control mode.

 Special metering auto compensation function.

 Management of distribution and production parameters.

 Realize operation management of raw material.

 Powerful false monitor and remind function.

 Convenient full auto control of the whole system.

 Strong search function of production data.

 Record and print main production data.

 Long-range diagnose function by Internet.
