Improving the Efficiency of the Ball Mill Is Key

Ball mill is a necessary equipment.so In grinding assignments, improving grinding technology efficiency has the important meaning to improve the dressing indexes. So how to improve the grinding technology efficiency? the following several aspects to improve the production efficiency:Firstly, adopt sealed grinding process: On the one hand, we can avoid a grinding, on the other hand, it can make the grinding medium (such as steel ball) completely work the ore grain bulky, and make the energy maximize. Therefore using the sorting machine or fine screen makes the second-stage grinding qualified grain give level, coarse grained is returned to grinding machines and grinds again(also called return sand).Secondly, using different grinding machine: The production practice shows, surrounding the discharging rod milling function can reduce a shattered. Especially for the fragile mineral, it is more meaningful. Because the row ore speed of these grinding machine is fast, big density ore drowned in the bottom of the pulp is removed easily, due to rod milling machine using the parallel ChangGang stick as grinding medium, so it can reduce a crushing phenomenon.Thirdly, the following aspects should be paid attention to grinding machine operation: 1. closed circuit grinding, should have proper circulation load; 2. grinding mill speed should be controlled properly; 3. put the ball system to be reasonable. With the quality of steel ball system including (density, hardness, wear line, etc.), steel ball size, the filling rate of steel ball and reasonable add, etc. In the production practice, turn rate 76 ~ 88% , filling rate by more than 40 ~ 50%.For hard ore ball diameter D = 5 dkFor medium hardness of ore ball diameter D = 4 dkD-ball diameter, mm; Dk -the largest size of grinding machine to mine, mm.4, ground pulp density should be appropriate, more low and high is bad, practice operation should pay attention to the adjustment of the water.At the present, Fote Heavy Machinery has set...
