A grinding mill is a large tubular machine with a crown gear driven by a pinion, which is driven by a reduction gear and electric motor. Some large SAG mills have what we call a wrapped motor drive, which is the motor fields are installed surrounding the entire circumference of the mill, with the mill
The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes. And the product of the large AG/SAG grinding is either a finished size ready of processing, or an immediate size for further grinding in a ball mill, pebble mill, or a VERTIMILL® or a stirred media detritor (SMD).
Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually ore or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
The ball mill is a key piece of equipment for grinding crushed materials, and is widely used in production of powders such as cement, silicates, refractory material, and glass ceramics, as well as for ore dressing of both ferrous and non-ferrous metals.
Ball mill is the most widely used kind of grinding equipment. Zenith Ball mills are widely used in various types of ores' benefication, electricity, ore and chemical industries. With high comminution ratio,it can carry out dry or wet pulverizing and can meet demand for sustainable large-scale production.

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.
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
