according to the experimental results, when the steel ball filling amount in ball mill barrel is 40%, the ball mill output is highest, but in actual production, the steel ball filling rate in ball mill barrel is mostly around 35%, keeping the steel ball volume in barrel slightly lower than the horizontal center line of ball mill. now, we have
nov 29, 2012 As we have known the varieties of ball mill, lets come back to the point and talk about the ways to increase ball mill efficiency. generally speaking, there are three simple and direct means to increase ball mill output.
the effective diameter of ball mill is mm, into the formula obtained 35.min. In generally, the real rotation rate of ball mill is between 76% to 86%, and the working speed of the ball mill can be the following value:
figure shows the active grinding area for an optimally charged ball mill. As the drum rotates, the media should ideally form a sloping pile that maintains a degree angle so that there is a constant cascading of media at the surface. because the media is falling the fastest and for the longest distance at the top of the pile, the majority
As may be seen in fig. a ball mill generally comprises a rotary drum 10, a separator 11, feed line and recirculation line for reintroducing coarse particles from feed line back into the rotary drum 10. the output grinding products passed by separator are withdrawn by way of output line 14.
the output decreases. reasons: the gap of the grate bar is blocked; the materials are not fed in an even manner. elimination ways: stop the machine and clean the tamper inside the gap of the grate bar; adjust the material feeding mechanism. there is knock on the elastic coupling. reasons: the pin roll is loose; the elastic ring is abraded.
