A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the balls, which may be made of steel ( chrome steel ), stainless steel, ceramic, or rubber.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum chunk size, product size as P80 and maximum and finally the type of circuit open/closed
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.

Rock Phosphate Milling Ball Mill Machine Buy Rock. The ball mill machine is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other
Florida rock is relatively free of organics and is for the most part no longer dried or calcined. The rock is maintained at about 10 percent moisture and is stored in piles at the mine and/or chemical plant for future use. The rock is slurried in water and wetground in ball mills or rod mills at the chemical plant.
Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls.
The Wet Pan Mill is also called a wet grinding machine. Based on the different structure it is divided into double roller grinding and three rollers, most often used is double rollers, the small rock ore material is fed into the inner grinding road by two workers.

Hard Rock Gold Processing Equipment Wet Pan Mill Machine. Product Description. Wet pan mills are also called gold mill, gold grinding machines, roller mills. Many users praised it for small investment, quick returns, low production costs, good efficiency, it is the best alternative equipment to the ball mill currently.
Ball mills are filled up to 40% with steel balls (with 3080 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.
If a ball mill uses little or no water during grinding, it is a dry mill. If a ball mill uses water during grinding, it is a wet mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
