Ball Mill Critical Speed. The mill speed is typically defined as the percent of the Theoretical Critical Speed often abbreviated as Cs. The Theoretical Critical Speed Cs of rotation is the speed in RPM at which an infinitely small particle will cling to the inside of the liners for a complete revolution.
The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the ball mill machine. The larger the diameter is, the slower the rotation is. If the peripheral speed of the ball grinding mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill.

The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media ceramic or metallic balls or rods, the product to be ground is added and the cylinder is put into rotation via an external drive causing the media to roll, slide and cascade.
The ratio of the barrel length to the diameter of the ball mill is small, and in most cases the ratio is only slightly greater than 1.In addition, the barrel mill speed is lower than the working speed of the same size ball mill, so that the medium inside is in a sloping state. 2.
Dec 22, 2019 In fact, ball mill slurry leakage is a very common problem, but it is not an inevitable problem. In order to prevent the ball mill from frequently leaking during the application process, I can prevent it in advance through technical methods. Here we have sorted out some common leaks of ball mills.
3. Ball Mill Daily Cleaning. The daily cleaning of the ball mill is mainly to prevent the ball mill body from corroding, rusting, even clogging, and abrasion caused by impurities, which will affect the daily production of the ball mill. Therefore, it is necessary to maintain the daily hygiene of the ball mill at all times.
