Dear Marius,

Before the ultra-fine grinding machine is started, it should be checked whether all the inspection doors are closed tightly. Check whether the gap between the jaws of the crusher meets the feeding size. Adjust the speed of the analyzer to reach the approximate grain size requirements. Then start up in order.

1. Start the bucket elevator;

2. Start the jaw crusher;

3. After the material is stored in the warehouse, start the analysis machine;

4, start the blower;

5. Start the main machine of superfine mill and start the electromagnetic vibrating feeder immediately after starting the host.

At this point, the ultra-fine mill grinding work begins. The operation sequence of the ultra-fine mill is as follows: start hoist → crusher → analysis machine → fan → main machine → feeder. When the ultra-fine mill is stopped, the machines should be shut down in the following order:

1. Close the feeder to stop feeding;

2. Stop the host after about one minute;

3. Stop the blower after blowing off the residual powder;

4. Turn off the analyzer.

The order of shutdown of the ultra-fine mill is: feeder → host → blower → analyzer.

Ultra-fine grinding mill is not allowed to refuel at any time during normal operation. To ensure reliable production, abnormal noise occurs in any part of the grinding mill, or the load suddenly increases, stop immediately to check and eliminate the malfunction, so as to avoid major accidents. When the power is turned on, the residual material in the mill is taken out, otherwise the current is too large when starting up, which affects the startup.
