Process Of Grinding Mills
Grinding Mills - Mineral Processing & Metallurgy
The raw material is fed in through a hollow trunnion at the entrance end of the mill and during grinding traverses the ball charge; after which it passes through the grating and is picked up and removed by the discharge scoop or is discharged through peripheral ports.

Wet mills can also be adjusted to reduce the likelihood of wear to the milling media or grinding chamber. If a product needs to be in a dry powder format, after wet milling it requires an energy-intensive drying process. Dry milling techniques, including fluidized jet milling with superheated steam can save this step, possibly also sparing costs.

In this process, we use machines for the fine grinding of solids of every hardness for any required end fineness. For the high nickel NCM, the LiOH is better than LiCO 3 for the Lithium source because of high chemical reaction. The target size of LiOH is approx. 7 – 8 micron(d50). And in this process, jet milling solution is needed.

Roller mill. With a roller mill, a product is compressed and reduced between two counter-rotating rotating rollers. A major advantage of this process is that the proportion of fine particles (powders or dust) remains minimal compared to other grinding principles and that a nice homogeneous grain-size distribution is achievable.
