cement mill |
Cement mill is an important cement line equipment, Critical speed is one of the main data to measure the cement mill is working. cement mill speed directly determines the effect of grinding media and grinding operations. If slow speed, then the lifted height of cement mill is small, their gravity cause diarrhea steel be down state, the impact is very small, but abrasive action is very powerful, even though it can improve the crushing rate, but the effect is too low.
When the cement mill speed exceeds a certain limit, namely a high speed, cement mill will not fall with the cylinder rotation, in a centrifuge operation state. At this time cement mill did not shock effect, abrasive and very small, so that the grinding action stopped. Cement mill in the outermost cylinder together with the rotation of the ball just does not fall, the time of ball speed is called critical speed.
All kinds of cement mill critical speed is proportional to its diameter D, absolute critical speed is not easy to obtain, only theoretical critical speed calculation formula has been widely used with.
It is not an easy thing to grasp the ball speed threshold, Hongji provides you with the most comprehensive and advanced cement line, and the best use of the program to ensure that customers maximize production efficiency.zrf
