Coal Mill Charge Ball Calculation. Cement grinding vertical roller mills versus ball millsement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding
The ball and tube mills are lowspeed machines that grind the coal with steel balls in a rotating horizontal cylinder. Due to its shape, it is called a tube mill and due to use of grinding balls for crushing, it is called a ball mill, or both terms as a ball tube mill. These mills are also designated as an example size, BBD4772,

Tube mills use steel balls as grinding media. Due to wear in the abrasive environment it is necessary to charge new balls periodically to maintain a steady balanced ball charge in the mill. The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill, have significant effects on the mill capacity and the milling efficiency.
Ball mill design for coal grinding little gujarat coal grinding from ball mill closed circuit diagramball mill for coal grinding design operatie003 ball mill powerdesign calculation example 2 in example it was determined that a 1400 hp wet grinding ball mill was required to grind 100 tph of material with a bond work index of 15 ( guess what mineral type it is ) from 80% passing inch to 80%
The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill, have significant effects on the mill capacity and the milling efficiency. Small balls are effective in grinding fine particles in the load, whereas large balls are required to deal with large particles of coal or stone contaminant. The steady state ball size distribution

optimum conditions for the grinding of an Indian coal. The grinding of coal may depend on several parameters however, in the present study the grinding time, charge content and number of balls in a ball mill are considered as parameters. These three parameters are most important parameters in grinding of coal which were ignored in previous works.
