The Hardinge mill, Fig., uses spheres as a grinding agent but the body is of cylindroconical form and usually has a length to diameter ratio intermediate between those associated with the ball mill and the tube mill. The reason for this form of construction is that it is found that, during, the operation of the mill, the largest balls ...

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Principle of SAG Mill operation SAG mill

Ball 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.

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.

Construction: The ball mill grinder consists following Parts: Cylinder: cylinder is made of a hollow metal that moves about its horizontal axis. the cylinder can be made of porcelain, metal, and rubber. the length of the cylinder slightly higher than its diameter. Ball: The ball lies in cylinders, which are made up of stainless steel, the size of the ball depends on the cylinder diameter.

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. 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.
