What Need to Notice When Test Running Ball Mill

We have talked about the preperation before test running the ball mill, so I think that moat of us may something about that more or less. But do you know what should we pay attention to the process of test running ball mill?

On the whole, we should pay attention to the test run of the load and operating time of ball mill. The detailed instruction about them is in the following:

(1) the idle running - no medium and material) 8 hours, mill system normal operation;

(2) into the design load a third of the grinding medium run 42 hours, adding suitable amount of water, coal and additive;

(3) into the design load two-thirds of grinding media running 90 hours, adding suitable amount of water, coal and additive;

(4) into the design load of 5/6 grinding media running 90 hours, adding suitable amount of water, coal and additive; More mineral processing technology, please log on to www.shiliaoshebei.comMore mineral processing technology, please log on to www.shiliaoshebei.com

(5) in all design load grinding medium running 72 hours, at the same time, adding suitable amount of material and process water.

(6) and quality check before commissioning test run start slow drive, slow drive 2, 3, check whether block movement, movement is normal, and travel switch mill rotating in the right direction, and then you can start the main motor.

1) the main bearing vibration amplitude shall not be greater than 0.6 mm;

2) main bearing temperature rise shall not exceed 30 ℃;

3) the big gear radial runout shall not be greater than 1.2 mm, face runout is less than 1.6 mm;

4) lubrication and interlocking device is flexible and reliable;

5) mill lining board and the connecting bolt, shock vibration in the operation, may be loose and broken phenomenon, therefore, should stop after load to run 24 hours grinding inspections;

6) packed in two-thirds of design load of grinding operation after 90 hours, cylinder and the end cover bolts should be tightened again....
