Before starting the control system of the asphalt mixing plant equipments, the following eight aspects should be considered: Is the limit switch normal? Is there any alarm appearing on the operating interface of the computer? Start the oblique belt and flat belt; Start the mixer; Start the mixing plant source air compressor pressure after 0.7MPa pressure to meet the surrounding pressure; Disable the automatic production of concrete switch, "prohibit concrete" file; Switch the operating table of the concrete mixing station control system from "manual" to "automatic"; Then turn on the emergency stop button switch, and then manually control the console power supply, PLC and instrument power supply display normal, open UPS, and turn on the computer for inspection.

The emergency stop switch of the asphalt mixing plant control system console, the key switch is in the off state, the wiring rack inside the console is in the OFF state, and the power switch on the main chassis is turned off without any load (under load, when the power switch is turned off, the cabinet may cause collapse.
When the asphalt mixing plant control system self-checks, special attention should be paid: If you are not proficient in the operation of the mixing control system, please strictly follow the steps below. Make sure that the computer input signal is normal. Open the silo bottom plate valve, admixture, feed valve, pump and water inlet valve. Fill the aggregate storage silo with materials, empty the mainframe, and the middle position of each object needs to be carefully checked.
Asphalt Replacement steps for wearing parts of the mixing station control system:
The material of the mixing blades and lining plates is wear-resistant cast iron, and the service life is generally 50,000 to 60,000 tanks. Please replace the accessories according to the instructions.
1. Due to the poor load and use conditions, the conveyor belt is prone to aging or damage. If it affects production, it needs to be replaced.
2. After the sealing strip of the main engine discharge door is worn, the discharge door can be adjusted to move up for compensation. If the adjustment of the discharge door bucket cannot press the sealing strip tightly and cannot solve the leakage problem such as slurry leakage, it means that the sealing strip is severely worn and must be replaced.
3. If the filter element in the powder tank dust collector is still not dust-removing after cleaning, the filter element in the dust collector must be replaced.
