SIZE REDUCTION AND SIZE SEPARATION -. Definition, objectives of size reduction and size separation, factors affecting size reduction, laws.

In some plants the performance of large diameter ball mills is not as efficient in energy consumption as predicted from the performance of laboratory and pilot-plant ball mills. . This determines the number of layers of balls in the mill and the proportion of impact, abrasion and attrition grinding that occurs in a specific ball mill.

Adiabatic shear bands were also found in balls which were used in the large industrial mill. A galvanic series of the minerals and grinding media materials was determined from electrochemical tests, indicating the tendency of each grinding material to corrosive wear. The effect of media composition and microstructure was.

Key words: ball mill, milling variables, power requirements, energy consumption. . influences the process efficiency as well as the quality of final . The main factors affecting the grinding action of the ball mill are speed of mill, refining time and quantity, type and size of grinding media. Even though the ball mills have found.

In ball mill, pulley and gear reduction mechanism is the key factors for cylinder rotating speed which is generally fixed. This speed will directly affect the grinding process. Ores and grinding media . Under this condition, grinding media will not create any impact force and grinding efficiency will be very low. In summary, when.

are considered as low efficient equipment. Laboratory tests using tumbling mills for batch grinding have been crucial to a better understanding of the variables that affect their development. These tests, when allied to adequate analysis tools, are able to elucidate all effects from operational variables on ball milling and also.
