When using a Sand dryer, when we must do all the preparation , ball speed regulation also requires specialized skills , if the speed problem modulation is not good, it will affect the mill 's production, consequences are very serious .

For ball speed control problem has been an area of concern , in fact, a ball mill grinding of mineral processing equipment during the time we had to use the most is on the speed control theory , while the actual operations are to be based on their feelings , in theory based on past experiences, can the perfect ball control . Based on years of experience , practical guide you how to better control the ball speed .

Mill speed directly determines the size of the cylinder body motion grinding media and grinding operations results. When the speed is low, the ball mill was promoted height is small, the ball itself gravity sliding from the top of the ball bearing rolling down , was spilled off the state, this time the ball impact is small, but highly abrasive ore mainly by grinding stripping and grinding, grinding effect is not high.

When the speed is high, the height of the ball is lifted high . Ball rises to a certain height from the cylinder, along parabolic trajectory whereabouts in Paola working condition. In Paola point has a larger impact on the role , the main ore was crushed by the impact , the highest grinding efficiency . When the mill speed exceeds a certain limit ( speed is high ) , the ball will not rotate with the cylinder whereabouts in centrifuge operation state . Then the ball just did not shock effect is also very small so that the abrasive grinding action is stopped .
