Computation of charging media for a double compartment cement ball mill
Coarse grinding is done in first chamber and the maximum size, which comes in second chamber, is less than 8 mm. Fine grinding is done in second chamber of ball mill. Air is sucked through the mill, which takes out the fine ground cement from the ball mill. Bucket elevator takes the fine ground powder from the ball mill to the separator.

Overflow VS Grate Discharge Ball or Mill – Why …
The cost of a ball mill conversion from overflow to grate discharge is 'fairly' affordable at $65,000 for a 13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber). A comparison in laboratory of Overflow …
Christian Pfeiffer
The outlet temperature of the material and the mill exhaust air from the mill always has to be >100°C. This ensures that the injected water is brought to evaporation and leaves the mill in the air stream. The energy required for the evaporation of the water is extracted from the material and the grinding ball charge, resulting in efficient ...
Cement Grinding
Space needed for vertical mill is much less than a closed circuit ball mill of same capacity. As separator is integral part of the mill itself, the number of auxiliary equipments are less. Total power consumption for grinding circuit as a whole is also less by about 30% compared to closed circuit ball mill in spite of higher fan power.
Ball Mill Feeders
The entire mill feed enters the drum via a chute or spout and an internal spiral carries the feed into the trunnion liner. The drum feeder may be used in lieu of a spout feeder when headroom limits direct spouting. The drum also provides a convenient method of adding grinding balls to a ball mill. The drum is generally lined with Manganese Steel.
A comparative study on a newly designed ball mill and the …
The mill with lifter arrangement in the diaphragm segment provided a separation zone in the discharge end of the mill that helped lift the desired particle sizes from the mill; however, balls and coarse size particles cannot be picked to the separation zone, leading to a relatively a higher percentage of the desired particle size distribution ...
Cement Mill Optimization: Practical Strategies for Enhanced …
Optimizing ball mill internals: The internal design of the ball mill, including the diaphragms, liners, and grinding media, can also impact the grinding efficiency. Using high-quality grinding media, optimizing the diaphragm design to improve ventilation, and regularly inspecting and replacing worn-out liners can result in up to 15% reduction ...
Ball Mill Design/Power Calculation
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of …
