Ball mill is a kind of high efficiency grinding mill, it also is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials. Therefore, its efficiency is directly related to the interests of the above industries. Generally speaking, there are three direct way to improve ball mill production capacity:
1. Setting fine crusher in front of ball mill;
2. Improve milling system to raise efficiency;
3. Add on high efficient separator.
Any one of the above 3 methods mentioned can greatly improve ball mill yields. Of course, if conditions permitting, comprehensively use the above 3 methods together is best, which is also a prevailing design trend for grinding system at home and abroad in recent years. Daswell is the professional manufacturer of complete sets of mining machinery, for example, mineral processing shaking table, powder making machine.
Relationships among the three ways: Fine crushing before grinding is a prerequisite, separating after grinding is guarantee, and mill reform. is fundamental. Fine crushing before grinding significantly reduces materials particle size, thereby reducing the grinding system load; the most direct benefit of improving separating efficiency is we can timely separate finished fine powders to the maximum extent and reduce the rate of re-crushing finished cement products so that lower mill load; and mill reform, that is improving grinding system, is the most fundamental solution, because a lower mill system will still makes bad effect not only on ball mill output, but also cement quality, even if particle size reduced and separating efficiency improved.
