Wet Media Milling In wet media milling, the mill feed material is first dispersed in a carrier fluid to create a liquid slurry before going into the drum with the grinding media, where it is recirculated until the desired particle size is achieved. Wet milling enables fine particle size results, uniform size distribution, and certain desirable
For drying the wet raw material it is necessary that prior to the mill start up the grinding plant is.heated for some time.Otherwise the cold grinding plant would take away too much heat from the drying process and the finish product would not be dry – handling problems in the meal transport and silo extraction would follow.
Raw milling can consume 10 30kWh/t; depending upon the materials and equipment, and developments aim to reduce this figure. Around 90 per cent of new raw mills are vertical roller mills, though many ball mills (commonplace until the 1970s) are still in use.

Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can handle moisture about 8%. ... (<0.5% moisture) and super fine (10-20% residue on 90-micron sieve) raw meal powder for clinkerization process in kiln (Dry Process). Grinding …
The ball mill can be operated in a wet or dry way, depending on the material properties and the intended use. The wet ball mill is usually preferred when the material to be ground is wet, such as in the case of ore processing. On the other hand, the dry ball mill is suitable for grinding dry materials, such as cement, limestone, and coal.
Grinding Action: The ball mill operates by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The …

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
