- Ball mill
A ball mill is a type of grinder used to grind materials into extremely fine powder for use in paints, pyrotechnics, and ceramics.
because of their sensitivity to impact. High-quality ball mills are potentially expensive and can grind mixture particles to as small as 0.0001 mm, enormously increasing surface area and reaction rates. The grinding works on principle of critical speed. The critical speed can be understood as that speed after which the steel balls which are responsible for the grinding of particles starts rotating along the direction of the cylindrical device;thus cause no grinding further.
balls. While usually very effective due to their high density and low contamination of the material being processed, stainless steel balls are unsuitable for some applications, including:
*Black powder and other flammable materials require non-sparking
lead, antimony, brass, or bronzegrinding media
*Contamination by iron of sensitive substances such as ceramic raw materials. In this application
ceramicor flintgrinding media is used. Ceramic media are also very resistant to corrosive materials.
High density alumina media (90 - 95% alumina ) is widely used in the ceramic industry to grind clay bodies, frits, glazes and other ingredients. It is more expensive than silica / silex media but is more efficient
*Ball-nosed milling cutters, sometimes informally called "ball mills"
