Two types of charge motion can be described cascading ... mill diameter (m) D = rod/ball diameter (m) ` Mills are driven at speeds of 50-90% of critical speed. ` High speeds = coarse grinding Rod Mill: ...
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
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). With the motor i will use a 40 mm pulley, because i have a 50 mm driven pulley, in one of my two shafts.
Cascading mill: a phenomenologicai design 81 that at any given time the cascading mill gives a finer distribution as the median size of the size distribution produced by the cascading mill is less than that of the ball mill. The difference in the grinding efficiency is more evident when the amount of production of fines is considered.

grinding effect. Normally there are two types of motion patterns that are cascading and cataracting[4]. When grinding media are moving in cascading, media move up with the mill shell till a certain height and then fall down along the surface of charge ramp. Rock material is grinded in the procedure of the media up-rolling and down-rolling.
Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results.

Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material. In tower mills, there is no cascading action as in standard grinding mills. Stirred mills are also common for mixing quicklime (CaO) into a lime slurry.
