Do you know how the automatic loading mixer is tested and operated when transporting heavy-duty concrete? The steps are as follows.
1. Determine the water supply according to the required concrete ratio, and adjust the time relay to the corresponding water supply time.
2. Start the mixing motor.
3. After the required mixture is added to the hopper, close the discharge door and lift the hopper. The hopper runs smoothly and can stop at any position of the track freely. After the hopper rises normally and the brake is reliable, feed the material into the mixing tank, start the water pump and supply water to the mixing tank.
4. Start the discharge valve after mixing for 25-35 seconds.
5. During the above test run, if any abnormal condition is found, stop the machine immediately to check and eliminate the fault, and then try to run it to normal again.
The heavy load trial operation of the automatic feeding mixer is as shown above. It is necessary to test the vehicle under heavy load. The driver must pay attention to this.
