Ball Mill Critical Speed & Working Principle 
Jun 19, 2015· If 75 percent of critical speed is considered desirable for efficient grinding in a 2.4 meter (8 foot) diameter mill, then the same will be true for a 5.0 meter (15½ foot) diameter mill. 
What it is the optimun speed for a ball mill
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 
Ball mill
Ball mill consist of a hollow cylindrical shell rotating about its axis. Axis of the shell horizontal or at small angle to the horizontal It is partially filled with balls made up of Steel,Stainless steel or rubber Inner surface of the shell is lined with abrasion resistant materials such as Manganese,Steel or rubber Length of the mill is 
Ball Mills  Orbis Machinery, LLC.
Ball Mills Our combined experience in ball mill design and process equipment development totals more than 60 years and allows us to put a unique spin on steel and lined mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s.

Ball mill  Wikipedia
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
