Ball Mill Working principle: When the ball mill works, motor and speed reducer transmit torque force to big and small gears of ball mill, so the barrel rotates.When the barrel rotates, Steel balls or other grinding media in the barrel are lifted to a certain height and fall …
A ball mill is a type of grinding mill, purposed similarly to the sag mill or other mining crushers. These machines are used to grind or mix metals or raw materials for further processing. These machines are used to grind or mix metals or raw materials for further processing.
Calculation of energy required for grinding in a ball mill. Int. J. Miner. Process., 25: 41-46. The Bond work index, Wi, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product.
The ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its axis.The drum of the ball mill (Pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.
Jul 19, 2013· stainless medium depends on how long your ball mill is. as for milling medium sizes, I go with a ratio one quarter 3/4" SS, half 1/2" SS, and one quarter 1/4". it needs to be enough to go from end to end of the tube on it's side, be able to have medium at the bottom, but still have medium able to travel up the curve to fall back down on itself ...
This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge.. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.
Dec 23, 2013· SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length. Vertical mill is used in grinding material at smaller particle sizes, which is used after ball mill.
JKTech Laboratory Services Bond Ball Mill Index Test (BRMWI) A Bond Ball Mill Index Test (BBMWI) is a standard test for determining the Ball Mill Work Index of a sample of ore. The BBMWI is a measure of the resistance of the material to crushing and grinding. It can be used to determine
