A ball mill, a type of grinder, is a cylindrical device used in grinding materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls,flint pebbles ...
126.96.36.199 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter . The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
The discharge diaphragm allows the ground material to pass but retains the grinding balls in the grinding chamber. Christian Pfeiffer adjusts the diaphragm individually to the existing grinding plant, fixing it either on the discharge mill head or floating on the mill shell.
Ball mill liners and diaphragm are used in grinding ball mill to line the inner tube of the ball mill in order to prevent severe wear and damage due to repeated impact to the body of the ball mill liners and diaphragm and usually manufactured in austenitic manganese steel and Hichromium hicarbon wear resistant white cast iron
Diaphragms for ball mills, Level Control Diaphragms HARDER WEARING, COST EFFICIENT DIAPHRAGMS FOR CEMENT MANUFACTURE Improved grinding media and liners can do much for productivity but the benefits can be reduced without equally efficient diaphragms.
For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
The discharge diaphragm allows the ground material to pass, but retains the grinding balls in the grinding chamber. Christian Pfeiffer adjusts the diaphragm individually to the existing grinding plant, fixing it either on the discharge mill head or floating on the mill shell.
In this way: There is no tension between the intermediate diaphragm and the mill tube, the mill tube is stabilized, while at the same time, relative movements and deformations of the diaphragm are avoided The structure of the intermediate diaphragm in the Monobloc® version supports the mill tube and works against deformation
