A ball mill is a grinding machine used to grind, blend, and sometimes for mixing of materials for use in geology, ceramics, metallurgy, electronics, pharmacy, construction material, and light industry, etc. Ball mills are classified as attritor, planetary ball mill, high energy ball mill, horizontal ball mill, or shaker mill. The working principle is simple; impact and attrition size reduction take place as the balls crash each other or the grinding wall.
The nanostructure can be formed by varying the number and size of balls, the material used for the balls, the material used for the cylinder, the rotation speed, and the material to be milled. Ball mills are commonly used for crushing and grinding the materials into an extremely fine powder. The sample material can smash and blend various materials and granularities. Materials particles can be downsized to as low as 0.1um. 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. When the plate rotates, the jar axis makes the planetary rotation in the opposite direction and the grinding media in the jar grind and mix sample at high speed.
