 — Typically in wet overflow grinding mills the product is allowed to exit the mill by overflowing the discharge trunnion. The driving force for flow of slurry from the feed to discharge end of the mill is the flow gradient due to the discharge trunnion being larger than the feed trunnion. However, grate discharge mills have a more complex mechanism.

Basic Mill Linings. Use rubber linings wherever possible due to lifetime, low weight, easy to install and noise dampening.; When application is getting tougher use steel-capped rubber, still easier to handle than steel.; When these both options are overruled (by temperature, feed size or chemicals) use steel.; Ore-bed is a lining with rubber covered permanent …

There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:

 — Grinding coarse ore in a ball-mill is done by steel balls of three sizes (5, 4, and 3 inches); fine ore is ground in a tube-mill by 2- and 1½-inch balls or by flint pebbles or by hard, rounded mine rock such as …

The ore pretreatment flow charts in use at most high-productive processing plants designed in the last decade are based on semiautogenous (SAG) milling and involve as a rule primary wet autogenous mill (WAM) and a series of ball mills. WAM is customary chosen either based on examination of analogous equipment specifications, or from the evidence

Ball mills grind various ores and other materials either wet or dry. There are two kinds of ball mills, grate type and overflow type, due to different ways of discharging material. There are many types of grinding media suitable for use in a ball mill, including Hardened steel, stainless steel, ceramic, flint pebbles.

 — The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills.
