Mineral Grinding Mill operation recommendations

                        

With the development of domestic industry, the demand for Mineral Grinding Mills is increasing day by day, but few companies will pay attention to the safety of Mineral Grinding Mills. Unknown irrational use and lack of attention to existing problems will bring unpredictable losses to enterprises.

Below, Shanghai Superfine Mill suppliers introduce the safety issues of Mineral Grinding Mills!

1. During operation, the monitoring parameters of the Mineral Grinding Mill must be adjusted. If the measuring device with inaccurate and bad quality is found, it should be discovered and contacted for repair.

2. When the milling system is normally deactivated, the coal sluice gate of the original coal hopper should be closed, the coal in the coal feeder should be drained, and the Mineral Grinding Mill should be ventilated for 5 to 10 minutes. The purge should be thorough and must be stored on the grinding disc. Coal, mill, separator, powder pipe, etc. may exist in the accumulation of powder. For the unit burning lignite, more attention should be paid to prevent the accumulation of powder in the Mineral Grinding Mill and the primary air duct.

3. After the grinding stops, close the hot air shut-off door of the Mineral Grinding Mill, the hot air regulating door, close the exit door of the Mineral Grinding Mill, close the cold air door of the Mineral Grinding Mill, pay attention to monitor the temperature of the Mineral Grinding Mill, when moving When the temperature of the crusher is higher than 70 °C, the Mineral Grinding Mill outlet door and the cold air door are opened for cooling.

4. Regardless of whether the Mineral Grinding Mill is operating or not, the CO concentration in the Mineral Grinding Mill should be closely monitored. When it is raised, if the Mineral Grinding Mill stops, the Mineral Grinding Mill exit door and the cold air door should be opened to maintain ventilation; If the Mineral Grinding Mill is running, the ventilation should be increased; to reduce the CO concentration and prevent the CO concentration in the Mineral Grinding Mill from reaching the explosion limit and exploding.

5. Before and after the start of the Mineral Grinding Mill, it is necessary to promptly eliminate the coal deposit in the coal crusher of the Mineral Grinding Mill; in normal operation, the stone coal of the Mineral Grinding Mill is discharged to prevent spontaneous combustion of coal in the stone coal box. In the case of poor coal quality and high stone coal, it is necessary to control the coal volume of the Mineral Grinding Mill to ensure the normal discharge of the stone coal system and prevent the blockage of the stone coal system.

6. When starting the Mineral Grinding Mill, it is necessary to control the outlet temperature of the Mineral Grinding Mill not to exceed 80 °C. If it exceeds 80 °C, it is forbidden to start the Mineral Grinding Mill, and increase the ventilation of the cold air to lower the outlet temperature.

7. The fire-fighting steam system of the Mineral Grinding Mill should be spared at any time, and the drain door should be fully open to ensure that the fire steam can be put in at any time. Once the outlet temperature of the Mineral Grinding Mill exceeds 100 ° C and cannot be adjusted back, it should be immediately put into the fire steam of the Mineral Grinding Mill.

8. The last point should be carefully checked to eliminate the powder leakage point and remove the leaked coal powder. When cleaning coal powder, open flames should be eliminated.

The above is a proposal for the use and operation safety of Mineral Grinding Mills introduced by Shanghai Superfine Grinding Supplier. If you have any questions, please feel free to contact us!
