The Grinding Mill Rules

Before the powder grinding is started, check if all the maintenance doors are closed tightly and the gap between jaw plates of the crusher match the particle size of the feeding material, and the rotating speed of the classifier shall be adjusted in conformity of the required fineness of the finished powder. At last, turn on the machine according to the sequence below:


  • 1. Turn on the dustpan elevator;
  • 2. Turn on the primary jaw crusher;
  • 3. Turn on the classifier after the hopper is fed with materials;
  • 4. Turn on the blower (It starts with no load. You can load when the blower runs normally);
  • 5. Turn on the main frame.
    And immediately after that, turn on the electromagnetic vibrating feeder. Then the power grinding is started. The sequence of operation is outlined as follows: Start, elevator → crusher → classifier → blower →main frame → vibratory feeder.
  • 5. In order to guarantee the production safety, the grinding mill must not be lubricated under the normal operation. If any part of the machines generates abnormal noises, or the load is suddenly raised up, turn off the machine immediately for checking and troubleshooting to prevent serious accidents. Before restarting the machine, take out the residual material first. Otherwise, the current will become so strong as to affect the startup operation.

Turn off the machine in the following sequence:

  • 1. Turn off the feeder and stop feeding materials;
  • 2. Turn off the main frame in one machine;
  • 3. Turn off the blower after blowing off all the residual particles;

  • 4. Turn off the classifier finally;

    The sequence of turning off the machine is outlined as follows: Feeder → main frame →blower → classifier. Note: The material is transported to the hopper by an elevator. When the material in the hopper reached a certain quantity, stop the crusher first and then the elevator. This operation depends on the quantity of the stored material.
