What is the reason of coarse material from ball mill

Ball mill is commonly used mineral processing equipment, but in actual production, the ball mill can not only be used as mineral processing equipment, but also sand, grinding, in the production line of a wide range of uses, so what is the reason for the ball mill discharge coarse?

The reasons for the coarse material of ball mill are varied, here mainly for you to introduce the following reasons:

1. The thickness of the material to be milled

Problem details: Generally speaking, the finer the ball mill material, the finer the finished material will be accordingly, and, for the dry grinding mill, the higher the moisture of the grinding material, the easier it is to cause saturated grinding, resulting in low mill output; on the contrary, the higher the output; the high temperature of the grinding material, it will be easy to happen that the material is sticky and sticky grinding media, reduce the operating efficiency of the mill, and reduce the output of the mill.

Solution: 

Strictly control the particle size of the incoming material, try to adopt the principle of “more breakage and less grinding”;

The moisture of the material is too high, the drying device should be configured before the mill to ensure that the moisture content of the material is within the permissible range of the mill;

Into the grinding material temperature is too high, first let the material cool down before entering the mill; if the mill temperature is too high, it will first stop the machine to cool down, and then carry out the operation.

2. Mill feeding unreasonable

Problem details: 

If the mill feeding is unreasonable, then the material crushing inside the crushing chamber will be uneven, resulting in the grinding material is too coarse.

Solution: 

Reasonable control of the feeding process, to ensure that the feed is uniform, the material can be fully processed

3. Influence of grinding aids

Problem details: Reasonable addition of grinding aids can reduce the material station sticky, improve the grinding efficiency, but unreasonable addition of grinding aids, often counterproductive, for example: unreasonable addition of grinding aids to the ball mill will cause the material to dry after lumps. Greatly reduce the output of the mill.

Solution: Be sure to choose a reasonable grinding aid according to the nature of the feed, grinding aid into the amount should be in strict accordance with the standard, before adding grinding aid can be queried before the material grinding aid ratio standards.
