WhatsApp: +86 18838072829Ball Mill Principle. Ball mills are a type of grinder used to grind and blend materials for use in various industries. The basic principle of ball mills involves two or more grinding media, such as balls or rods, rotating in a container to grind materials to a desired fineness. The principle of ball mills is based on impact and attrition.
WhatsApp: +86 18838072829If a ball mill contained only coarse particles, then of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as the particles pass through the mill.

WhatsApp: +86 18838072829Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually times the shell diameter (Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
WhatsApp: +86 18838072829It 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. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls.
