(a) grinding machine is not allowed to overload (the ball) and Yu supply work, under the condition of using regular quantitative entrance from the feeder in the process of adding grinding medium (the ball).
(2) the main bearing grease injection once per class, and often pay attention to the temperature rise is normal, motor voltage, current, temperature, sound.
(3) periodically check lining board screw fastening, prevent loose lining board, displacement or loss caused by accidents.
(4) check the size of the gear, main bearing, classifier reducer lubrication situation of transmission parts, etc.
(5) observed before and after the end cover, cylinder, exhaust trough, classifier overflow tank sand return sand blockage or leakage.
