Classifier Ball Mill. There is also on the market a rib-cone screening ball-mill whose "classifier," as it may be termed, is part of the mill. Capacities for prospectors are 2 to 4 and 4 to 8 tons through 35 mesh in 24 hours, requiring 1½ to 3 horsepower. The screen is as the discharge end of the mill.
Air classifiers are often used in closed circuit with grinding mills, such as ball mills, hammer mills, roller mills or jet mills. The air classifier is used to select the onsize material and return the oversize to the milling system.
In this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 μs. This means that 77.1 per cent of the particles in the mill are 'coarse' and that 77.1 per cent of the mill power is being used 'effectively'. Conversely, 100-77.1, or 22.9 per cent of the mill contents are 'fine' and are being ...

Ball mill circuit classification system performance is considered here first because it provides the basis for subsequent characterization of ball mill breakage efficiency. Major design and …
The ball mill has higher circulation load, it generates only 30 -35% of actual fines you require to be called as product. If your product size needed is passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron.
The classifier is commonly used in the grinding circuit of the ball mill to separate the particles that are too large or too small for the subsequent processes. In this article, we …
Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.
Efficient classification involves accurately separating desired particle sizes from a moving airstream.

Thus, if the free minerals can be immediately removed from the ball mill classifier circuit, there is little chance for overgrinding. This is actually what has happened wherever Mineral Jigs or Unit Flotation Cells have been installed in the ball mill classifier circuit. With the installation of one or both of these machines between the ball ...
The profiling of the shell lining plates creates the movement of the ball charge, which causes the grinding of the material. It is therefore essential for effective grinding in the mill and far more than just a wear part. The exact profile shape has to be defined depending on the ball sizes used, the rotation pace and the mill diameter.
