A ball mill crushes solids into a fine powder within a rotating drum, using balls as the grinding medium. Applications. Ball mills are found in settings as diverse as laboratories and mines, among others. Technologies. Ball mills can grind in either a wet or a dry environment.
A ball mill is a type of grinder used to grind or 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.
Teflon® balls excellent resistance to corrosion Low weight fluorinated semicrystalline polymer balls, they provide exceptional corrosion resistance and are used into high temperature applications. Mechanical and wear resistance properties are lower than other plastic materials.
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.
The ball mill contains a hollow cylindrical container that rotates about its axis. These cylinders are made of stainless steel, Alumina Ceramic, Agate, Zirconia, Teflon, Nylon, and Polyurethane. In a laboratory planetary ball mill, four or two ball grinding jars are to be installed simultaneously on the turning plate.

Teflon balls are recommended for applications where lightweight, non metallic, and erosion resistant properties are required. Teflon balls have a maximum work temperature of 550°F.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter . The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
When charging a ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product. Charging a Wet Mill The general operation of a grinding mill is to have the product impacted between the balls as they tumble.
The wet ball mill can be divided into three types according to the motion characteristics: a simple swing type wet ball mill, a complex swing type wet ball mill, and a hybrid swing type wet ball mill.
