What it is the optimun speed for a ball mill

19/10/2006· Congratulations on your ball mill! You'll want to further reduce your motor speed by 3:1 to mill more efficiently. Right now, your RPM is just slightly under the speed where the media won't do any work. The optimum speed for your jar to turn is around 90 RPM like Frozentech said.

What it is the optimun speed for a ball mill

19/10/2006· 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). With the motor i will use a 40 mm pulley,because i have a 50 mm driven pulley, in one of my two shafts. In the other side of my shafts there are two 40 mm

Ball Mill Motor Power Draw Sizing and Design Formula

The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.  Rod and Ball Mills by C.A. Rowland and D.M. Kjos @ Allis-Chalmers

RPMs on a ball mill and a star rolling machine

Don't know about the roller, but the optimum speed for a ball mill depends on the size of the jar and media. There's a formula for calculating this, I don't have it around but it is in Lloyds book. However, for a 6" jar and 3/4" media it should be appr. 75RPM. It decreases with jar size and increases slightly with media size.--Eirik M I see fragged people. Dan Cutter 2003-12-19 01:42:05 UTC

Ball Mill: Operating principles, components, Uses

Rotation speed of the cylinder. Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills. Contents. 1 Pharmaceutical uses of Ball Mill; 2 Advantages of
