70% passing 75 microns. Grinding is effected in 8 parallel lines of 8x5m ball mills in a closed circuit with cyclones. The make-up balls are 80-mm forged alloy steel balls and the average ball consumption is 750g/t of ore ground. In order to optimize ball size distribution inside the mill, based on the previous investigation

Ball milling is a type of grinder used to grind materials into fine powder. Ball mills rotate around a horizontal axis, partially filled with the coarse salt to be ground plus the grinding medium. There are many types of grinding media suitable for use in a ball mill, each material having its own specific properties and advantages.

torque mill test is the mill energy input divided by the solids load. The energy specific cumulative grinding rate at each screen size is calculated from a torque-mill test as in the example that follows. Torque mill solids load during test: 11.25 kg (24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

grinding below micron size. Fine grinding abrasive materials is typically needed to create particle sizes in the minus 50 mesh range 297 microns down to about 95 minus 325 mesh 45 microns Some of these sizes are typically referred to as talc flour pulverized or ballmill fine grades Following are three different types of machines that can be used to obtain the

The larger particles from this mill are returned to the S.A.G. mill for more grinding. The finer particles receive more grinding in a ball mill, and are size classified to give a final product of 80% < microns. See more detail on grinding and sizing. 5. Leaching and adsorption

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ...
