In the tests, a by industrial tubular ball mill driven by a threephase motor (YTM6306, 1000 kW, 985 r/min) was operated at rpm (77% of critical speed). In the mill, the charge of steel balls was made up of three different diameter balls: 40, 50 and 60 mm corresponding to 40%, 40%, 20% mass ratio, respectively.

For a coal mill, we usually recommend a light classifying liners and for raw mills we recommend heavy classifying liners. If the raw materials are particularly coarse, a mixed solution might be best. This could be either by replacing the first few rings , the first m of the chamber with step lining or combining wave lining
Ball mills are always preferred to be operated at full capacity because the power consumption of this type of mill is very high at lower loads when compared with other types. Ball mills can be designed for a very high capacity like 75 tons per hour output for a specific coal. Vertical spindle mill. There are many different varieties of vertical ...

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
A coal ball is a type of concretion, varying in shape from an imperfect sphere to a flatlying, irregular slab. Coal balls were formed in Carboniferous Period swamps and mires, when peat was prevented from being turned into coal by the high amount of calcite surrounding the peat; the calcite caused it to be turned into stone instead.
Ball Mills: A ball mill is a cylindrical machine with a horizontal axis, some of which contain grinding media such as steel balls or steel rods. The mill receives coal feed and grinds it by the impact and friction of rolling balls. For grinding coal, ball mills are frequently used in cement factories and coalfired power plants.
