of ball mill feed sample from plant survey. sample is reconstituted with water to be the same percent solids as the plant ball mill discharge. mill speed: 35.2 rpm length of time of test: 363 seconds average torque reading: 1,056 in-lbs mill HP (35.2 rpmthese tests were done with a 0.82 grate discharge mill with a mm graded ball charge and a 30% filling degree. the mill discharge pulp density was increased from 68.8% to 75.9% solids. the data is summarized in table iii. the example in table iii illustrates that the density has a large influence on the grinding efficiency. In this ball mill designpower calculation. the basic parameters used in ball mill design rod mill or any tumbling mill sizing are; material to be ground, characteristics, bond work index, bulk density, specific density, desired mill tonnage capacity dtph, operating solids or pulp density, feed size as and maximum chunk size, the ball mill feed is percent plus 106 the ball mill discharge is percent plus 106 um. the circuit cse is percent. this is the estimated percentage of plus 106 solids in the ball mill, and also the percentage of the ball mill power effectively applied to the grinding

first, a jar mill grindability test requires a lb. sample and produces a direct measured specific energy to grind from the design feed size to the required product size. the second test, a bond work index determination, results in a specific energy value from an empirical formula.ball mill trunnion bearing lube system view larger image On a 116 220 ball mill the trunnion bearing lubrication system provides continuous low pressure flood oil for cooling and lubrication of the bearings and high pressure oil for hydrostatic lift of the feed and discharge trunnions during. ball mills for various applications gebr pfeiffermetallurgical contentball mill maintenance manualon mill installation and maintenanceball mill concrete foundationsgrinding mill mill sole plate Am sure your ball mill is considered the finest possible grinding mill available. As such you will find it is designed and constructed according to heavy duty specifications. It is designed along sound jun 23, 2020 converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. the grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. ore properties, feed and product sizes, recirculating load and other operating
