    Ball Mill Shell Vibration System Analysis . Normally, there are millions of balls inside the mill. Theoretically, these balls arrange in different layers. They impact the mill shell direct or indirect with different amplitudes and periods. Thus, the mill shell vibration signal caused by these forces must be consist of sub-signals with different

    The ball mill contains a hollow cylindrical shell that rotates about its axis. This cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it. Ball mills are classified as attritor, horizontal, planetary, high energy, or shaker. Grinding elements in ball mills travel at different velocities

    A ball mill is a type of size reduction machine used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics. 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
