The automatic loading mixer will run in when transporting heavy load concrete. Do you know how to carry out the test run? Here are the steps.
1. The water supply is determined according to the required concrete proportion, and the time relay is adjusted to the corresponding water supply time.
2. Start the mixing motor.
3. Close the discharge door and add the required mixture into the hopper. After lifting the hopper, the hopper should run smoothly and stop at any position of the track freely. If there is slippage, the hopper should first be put into the bottom of the pit and then adjust the large nut on the brake motor. After the hopper is lifted normally and the brake is reliable, the material is fed into the mixing tank, and the water pump is started to supply water to the mixing tank.

4. After mixing for 25-35 seconds, start the discharge door to unload.
5. In the process of the above test run, if abnormal conditions are found, stop the machine immediately for inspection, remove the fault, and then test again until it is normal.
The heavy load test run of the automatic feeding mixer is described above. It is very necessary to test run the vehicle under heavy load. The drivers must pay attention to it.
