Ball mills are commonly used for crushing and grinding the materials into an extremely fine form. The ball mill contains a hollow cylindrical shell that rotates about its axis. This cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it.
What is a wet ball mill? A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.
Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills is typically 75 vol. % ore and 25% steel. The ball mill is operated in closed circuit with a particle size measurement device and size control cyclones.
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc., as well as for ore dressing of ferrous and non ferrous metals. The ball mill can grind ores and other materials, wet or dry.
9.1 Report the Wet Ball Mill value to the nearest whole number. Note 3This test furnishes valuable supplementary data pertaining to the quality of the aggregate portion of flexible base material. The Wet Ball Mill test is more reliable than the Los Angeles abrasion test in evaluating the quality of base materials.
The ball mill host comprises a cylinder body, cylinder body made of inlaid useful wear resistant material bearing cylinder liner, and maintain its rotation of the bearing, but also have the driving part, such as a motor, pulley,transmission gear, V belt etc.. Ball Mill Working Principle

The vertical ball mill has stable performance, supports dry and wet grinding, and has unique performance for coarse and thickened materials. Vertical ball mill can be widely used for dispersion and grinding of solid or powder materials in paint, medicine, building materials, chemical industry and other industries.
Wet ball mill is a kind of equipment which uses grinding medium and a certain amount of liquid to grind materials. Unlike dry ball mill, wet ball mill adopts the wet grinding method. The characteristic of wet grinding is that the material needs to be soaked in the liquid for grinding.
This type of mill can crush materials which are too large to be fed into the tube mill. Ground materials are dried by the flue gas from the kiln. Fig.2 Schematic process flow of vertical roller mill for grinding of raw materials Vertical roller mills are adopted in 20 cement plants in Japan. Results
