Basic state of polishing body movement in the ball mill

　　The rotation speed of the ball milling cylinder and the filling rate of the grinding body have a relatively large effect on the effect of the grinding material. When the cylinder is rotated in different speeds, the grinding body in the ball mill may exhibit three basic states: the rotational speed is too slow, the abrasive body and the material are brought by the frictional force to be equal to the height of the moving friction angle, the abrasive body and materials.

　　The decline is called "pouring state", which has a grinding effect on the material, but the impact of the material is small, which makes the grinding efficiency are not high; the speed of speed is too fast, the abrasive body and the material are inertialy centrifugal force The body is rotated, called "turnaround state", and the abrasive does not get an impact and grinding of the material; the speed is relatively appropriate, and the grinding body is raised to a certain height, it is called "thrown state", abrasive material Larger impact and grinding effect, high grinding efficiency. (The article is published by the ball mill price, the article is for reference only) When the ball mill is actually operated, the motion state of the grinding body is very complicated, and there is attached to the ball mill wall to move, and there is a downward wall and the abrasive body There is a parabolic shift, a rotation or scroll around the axis.

　　The basic effect of the grinding body is the result of the comprehensive application of the above-mentioned movement on the material, and the most important one can summarize the impact and grinding. Ball mills The basic effects of the crushing material are to determine the reasonable motion state of the abrasive body, which can correctly select the basis for calculating the work speed of the ball mill, the required power, production capacity provides design.
