The closed-circuit grinding system of the ball mill is shown as follows materials mixed in a certain proportion will firstly enter the cement ball mill for grinding and then be sent to the powder concentrator by bucket elevator. The powder concentrator divides the materials into coarse and fine materials. Fine material is the material that reaches the fineness requirement of the finished product. They will be collected by bag filter and sent directly into the cement silo. The coarse materials should be sent back to the ball mill for regrinding.

Apr 15 2004nbsp018332A closed-circuit grinding system using a continuous vibration ball mill has been applied to the production of fine particles. However in most cases the operational conditions are determined empirically. The reason for using empirical operational conditions is that it is difficult to estimate grinding performance.
The closed-circuit grinding system all ground materials are led into a separator and classified into refined powder products and coarse powder return powder. The coarse powder is returned to the ball mill and ground again with newly-fed raw materials. Following benefits can be realized with this technology

Ball Mills. RSG Inc supplies dry ball mills in the range of 5 HP 3 Kw to 5500 HP 4200 Kw. Dry ball mills are effective grinding systems in the general range of 500 microns down to 5 microns. Continuous milling systems are generally used in closed circuit with an air classifier. These ball mills are normally used in closed circuit milling in conjunction with the RSG high efficiency classifier.
