A ball mill consists of various components that work together to facilitate grinding operations. The key parts include the following: Mill Shell: The cylindrical shell provides a protective and structural enclosure for the mill. It is often made of steel and lined with wearresistant materials to prolong its lifespan.
Working of Ball Mill. The ball mill works by introducing the material to be ground into the feed hopper. The material is then pulled into the mill by the rotation of the drum. As the drum rotates, the balls inside the drum strike the particles, breaking them down into smaller pieces. The ground material is then discharged through the discharge ...
