ball mill classification | Henan Deya Machinery Co., Ltd.
The trunnion overflow mill is the simplest to operate and is used for most ball mill applications, especially for fine grinding and regrinding. Energy consumption is said to be about 15% less than that of a grate discharge mill of the same size, although the grinding efficiencies of the two mills are the same.

Grinding capacity is influenced by the size of balls
May 13, 2022The Azzaroni equation indicates that the correct ball size for the 2.93 m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill.

High Recirculating Loads In Ball Mill Circuits
The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is, for every incremental increase in circulating load of ...

Under the same condition, the cement mill output will be increased if the circulating load in the cement mill is increased. But the larger cycle load rate will make the powder efficiency decline, many qualified products cannot be selected out, back to the grinding cycle, limiting the increase in the cement mill output. This is a paradoxical state.
