Welcome to Shanghai COR Mining and Construction Machinery Co., Ltd.
Dear Doc: I installed a variable-speed drive on a cylindrical grinder. The wheels start at 18" and stub-out at 15". Should I increase the rpm as the wheel diameter gets smaller? The Doc Replies: If you want more consistent grinding, maintain a constant surface speed. The basic equation is: new rpm = original rpm × original diameter ÷ current diameter.
Oct 19, 2006· What it is the optimun speed for a ball mill ? - posted in Pyrotechnics: I have done a ball mill, recenly finished, but the motor has too rpms, is too fast for use in a ball mill (the pvc cylinder that i use, left of the shafts).

The actual dispersion system in a bead mill consists of a milling chamber and an agitator; the milling chamber is filled with the grinding beads (material e.g. glass, zircon oxide, steel) and the product to be dispersed. In the milling vessel, the grinding medium is kept moving by the agitator, which itself is driven by a motor.

Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size - mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media.
Dec 26, 2017· Several factors affect the efficiency of a ball mill for cement grinding.

Mar 15, 2003· In the example mentioned, changing from 6,600 rpm to 7,700 rpm multiplies the speed by 1.167. However, the corresponding centrifugal force would multiply by a factor of 1.167 × 1.167, or 1.36. To take a more extreme example, consider the same wheel with a maximum safe operating speed of 6,600 rpm run on a 5-inch right angle grinder at 10,000 rpm.

(I would guess around 1500 RPM). The constant seems to be the speed. It seems to happen between 24-26 MPH, which just happens to be when it shifts sometimes. If I accelerate too hard I never hear it. If I don't accelerate at a constant speed, then I do not hear it. So at a constant RPM, right around 25 MPH, I hear the grinding sound.
