1. Introduction
When we buy a ball mill, the manual will have detailed technical parameters, which include the range of output. Usually, the output of ball mill will remain normal in the beginning, but after running for a period of time, the output may become lower. So, what are the reasons for low output of ball mill?
2. Reasons for low output of ball mill
✱ Saturation of ball mill
When the output of ball mill becomes lower and lower, the first reason to consider is whether the ball mill is saturated, it is the culprit affecting the output of ball mill.
There are several reasons for saturation of ball mill. The reasons include: ①too much feed. ②harder and larger of the feed. ③high moisture content of the feed. ④unreasonable grading of steel balls. ⑤ blockage of partition board.
✱ Too long grinding time
If grinding time is too long, it would cause over-ground of the feed, which lead to too fine particles. This will reduce the processing capacity of ball mill, thereby reducing output.
✱ Failure to add steel balls in time
Both grinding effect and output of ball mill are restricted by steel balls. Due to long time grinding and impact in the chamber, steel balls will be wore out, so adding steel balls in time is an important factor to ensure the output of ball mill.
✱ Too high temperature in the chamber
When temperature is too high in the chamber, the material will adhere to the lining, causing agglomeration. This will result in reduced grinding efficiency and increased power consumption. At the same time, high temperature will be not conductive to the safe operation of the equipment.
✱ Equipment failure
During the operation of ball mill, if any failure occurs, such as damage of bearing or belt, will also cause low output of ball mill.
3. Summary
If the output of your ball mill is getting lower and lower, you can check against above reasons. Finding out the root of problem that affects efficiency and output of ball mill is vital to improve economic benefits.
