High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.
The normalized hardness of the material with the size of 100mm specified in the standard should be kept at HB160217, but it is difficult to exceed HB170 in fact. The combined transmission of the pinion with the surface hardness of HRC4550 will reduce the service life. Our Solutions to These Problems Select the best lubrication method
Cement Ball Mill Maintenance Replace the lubricant within the specified period. The lubricating oil at the main bearing of the newly installed mill shall be completely renewed after the mill runs for 1 month. Regularly check the quality and quantity of lubricating oil, remove impurities in the oil, and replenish in time.
