Machine ball mill is a type of grinder used to grind materials into a very fine powder. These machines are usually used in the manufacture of paints, ceramics, cement, fireworks, coal, pigments, feldspar for pottery, and powder laser for 3D printing machine. In general, its working principle is to reduce the size of the material by utilizing the movement of the ball down at the top of the shell.
Machine ball mill consists of a hollow cylinder that rotates on its axis. The axis of the spindle-called shell that stands horizontally. Media penggilingnya can be made of steel, stainless steel, or rubber. The inner surface of the cylinder shell is usually coated with a material that is not easily eroded as manganese ore and rubber.
Ways of working :
First of all material put into the machine through a cone on one side, and the output will be out of the cone on the other side. When the shell rotates, the ball is lifted and parts will cascade up and down. The movement of the ball is what will reduce the size of the material.
The advantage to wearing a ball mill machine in the production process, among others:
Low installation costs
The electrical energy required is relatively low
It is used for the production of which operate continuously
Can be used for all types of materials with high density
Suitable for use as a grinding machine in an open area
In addition to machine ball mill above, there is also a kind of planetary ball mill machine. The difference is the size of the smaller planetary ball mill as commonly used in the laboratory to grind material samples to a very small size. Planetary ball mill consists of a grinding wheel arranged through the sun. The speed difference between the grinding balls is what produces the interaction between the frictional forces thus creating a dynamic high energy.
