The overflow ball mill is a popular ore beneficiation machine used by many mining enterprises and customers. Today our experts will share some basic knowledge of ball mills about the overhauling standards with customers.

In most cases, the repair cycle of the overflow ball mill can be divided into: one month for frequent repair, 1-3 months for minor repair, 12-24 months for medium maintenance, and 60-120 months for heavy repair or overhauling. The concrete repair and maintenance process is as follows:

1.The frequent repair of the ball mill mainly refers to checking the oil volume, adjusting space between components, strengthening screws, replacing scale boards, checking the wear scale boards or mending the feeding device.

2.The minor repair means to check, clean and measure the abrasion of the gear surface and the scale board; change them if necessary.

3.The medium maintenance includes the following processes: changing the feeding components, changing the driving pin roll and bearings, checking the reducer box. When the rack wheel runs for about 3-5 years, they can be adjusted and changed according to their physical condition. The hollow shaft should be measured after being used for 3-5 years.

4.Overhauling of the overflow ball mill: inspect the machine under disassembled condition and then clean and measure it. Considering the wear condition, repair or change the components like rack wheel, hollow shaft, ball surface tile, driving shaft, pin roll and cylinder. After the ball mill goes through the heavy repair, users should test run the it before putting it into normal application.
