Ball mill grinding positions there are many reasons for the transformation

Mill "running rough" is that the grinding fineness of the product was coarse, are difficult to control abnormal phenomenon, generally in the ratio of length to diameter is relatively small on the two-position open-tube mill. Ball mill run rough not only cause a waste of energy, large size will impact on the subsequent sorting, so the actual production to try to avoid the occurrence of coarse mill run.
Mill "running rough" is mainly due to the ability of coarse position too strong, fine grinding compartment capacity is insufficient. In this case, even if due to lower mill output, fineness of the product is still coarse. Here Yu Fung Manufacturing Co. mill ball mill to introduce you to run rough concrete solutions:

First, the transformation equipment: In the coarse grinding compartment and more with 1 - 2 small balls or appropriate to increase the filling factor of finely ground positions, in order to increase the lifting capacity of the material and grinding capabilities; at the feed end of the preceding one, two circles liner, each block can be welded to form a 15 - 20mm square steel ribs; using corrugated liner; replace worn more serious backing.

Second, the change process: mill and spiral classifier machine used to form a closed circuit grinding process, effectively avoid the phenomenon of excessive coarse crushing and ran. Closed-circuit grinding, to force the coarse repeatedly failed to pass by a ball mill until the mill so far. Second, because a lot of grit to enter, so that the ball mill feed to the coarse fraction content increased, according to the principles of Hongxing school, then to maximize energy for useful work, so the grinding speed, productivity increased. In addition, since the amount of sand back to the existence of a new mill can eliminate fluctuations arising from the ore particle size of the product.

In addition to these solutions, the Yu Feng developed ultrafine mill laminate from the mill, and its port of discharge from the mill is located in the lower part of the other side, filling up to 45 percent, can make the minerals in the mill shell in the same residence greatly improve the impact period and the number of grinding, and a lattice sieve port of discharge, effectively prevent the occurrence of rough running.
