Construction of Ball Mill. The ball mill consists of a hollow metal cylinder mounted on a shaft and rotating about its horizontal axis. The cylinder can be made of metal, porcelain, or rubber. Inside the cylinder balls or pebbles are placed. The balls occupy between 30 and 50% of the volume of the cylinder. The diameter of the balls depends on ...
The Conical Type Ball Mill is most efficient when compare with cylindrical mill. Classification and circulation within the mill is the principle of operation for the conical mill. In a cylindrical mill most of the work is accomplished in only a portion of the mill cylinder length and the end corners are in effective. In conical ball mill it is ...
What Is The Conical Mill Principle? The Conical Mill sieves all particles ground to size through the sieved mesh on the Conical Mill screen. But first of all, the material to be ground is fed into the feed inlet by hand or gravity. These particles are ground inside the feed inlet and are then moved into the conical sieve chamber.
