Center Drive Ball Mill: The drive power device is in the center of the fuselage, and the motor realizes the operation of the ball mill through the reducer. In operation, the hollow shaft in the center of the ball mill drives the grinding body to rotate under the drive of the power system.

Overflow discharge mills are used when a product with high specific surface is
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,,

Grate discharge Dry Grate discharge Wet Overflow discharge Wet Figure Effect of mill filling on power draft for ball mills. The data is taken from Rexnord Process Machinery Reference Manual, Rexnord Process Machinery Division, Milwaukee, 1976 The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure
#0183;#32;In Figure C, the discharge opening is at the centre of the mill, while the feed is from both ends of the mill. The mills are therefore designated as a Centre Periphery Discharge mill . The diameter of the feed trunnion is slightly smaller than the discharge trunnion opening to facilitate flow of slurry through the mill and to prevent the slurry from trying to discharge through the feed trunnion.
The doublefaced birotator discharge diaphragm Optiflow#174; is installed in double rotator mills with peripheral discharge. It can be used with the Optidry#174; and both together make a coherent set of diaphragms. Optiflow#174; is adaptable to any quantity and dimension of the discharge openings in the mill
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and 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, and stainless steel balls.

or double helical scoop feeder. Several types of ball mills are distinguished depending on the discharge system and these types are commonly known as overflow discharge mill, diaphragm or grate discharge mill and centreperiphery discharge mill, see [23]. In industrial applications, the inner surface of the mill
The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed through the central hole in the discharge cap or through the grid (mills with center unloading the milled product and mills with unloading the milled product through the grid).
#0183;#32;Grate discharge mills give less excessive grinding compared to overflow mills and are best suited to grinds to 150250 m. In Figure C, the discharge opening is at the centre of the mill, while the feed is from both ends of the mill. The mills are therefore designated as a Centre Periphery Discharge mill.
Ball mills are used for grinding of rocks, cement clinker and lizenithne from 10 the center of the mill with periodic boundary conditions in the axial direction. operation that can lead to large increases in mill efficiency and throughput. axial transportation of fine material in a ball mill that is able to discharge from one end.

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal.
Ball mills are usually the largest consumers of energy within a about the mill operation is vital. An innovative tool which can deliver information about inmill dynamics has been developed by mill discharge product size in relation to the lifting effect of the liners.
A rod mill differs from a ball mill in that the comparatively rigid grinding media operate in a relatively fixed path and reduction results fram line rather than point contact between grinding surfaces. Conventional rod mills are either high or law discharge. In the high discharge mill, the discharge trunnion. is. the same size or only slightly
