Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance.
Mar 21, 2007 The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebblesrocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports reaching 100 mm instead of normal grate openings to increase the ...
The dry ball mill machine adopts grate plate mill tail discharge and straight barrel outlet discharge. The discharge is smooth without swelling grinding. The cylinder does not require cooling, has a long service life and a low failure rate.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
