Feb 13 2017 11 Working Principle Operation 12 Rod Mill Capacity Table 18 Ball Mill Grinding Circuit 19 Ball Mill Specifications In most cases it is desirable to operate the grinding mill in closed circuit with a screen or classifier as higher linings for wet or dry grinding for continuous or batch type operation

Batch Laboratory Ball Mill The Open Batch Mill makes possible simulation of grinding in a ball millclassifier circuit by grinding a fixed time then hand classifying with a sieve and a bucket and returning the sand to the mill for further grinding Pulp volume can be kept at a minimum by control of wash water since the ball load does not dump out

1 Introduction Over the years ball mill circuits closed with cyclones have become an industry standard and since the early days it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding ie
