grinding applications and to give an overview of the equipment which is available. Material grinding is quite often an integral part of an industrial process, whether carried out on a large or small scale and in some cases the grinding mill may be the single most costly item for the production operation. Installing a grinding

Practical applications have ... grinding mill load (GML) should be monitored closely to avoid overloading [4], [5]. ... Due to the knocking and tumbling actions of the grinding media within the revolving mill, ores are crushed to fine particles. • The spiral …

Tumbling mills are main equipment of mineral industries. These mills with a giant cylindrical configuration with the diameter of 10–12 m are used for the grinding of ores. Semi-autogenous grinding of ore plays a vital role in a mineral processing plant.

Thus, it is the extremely wide range of applications, and the great industrial importance, of the mills which constitute the "tumbling mill" family which forms the justification for the present work. The great range of sizes covered by industrial ball mills is well exemplified by Fig. 1.1 and Fig. 1.2.

The power draft and grinding efficiency of tumbling mills depend solely on the motion of the grinding charge and the ensuing ball collisions that utilize the input power to cause particle breakage. Power draw analysis was first attempted by Davis (1919) by considering the dynamics of the ball charge through individual ball paths and velocities.

The power required to drive a tumbling mill is of interest both to the designer and to the mill operator: to the former as a basis of design for the determination of the necessary size of the elements of the machine; and to the latter because all other factors being equal, the most economical machine is that which demands a minimum power for driving.
