Ball Mills - an overview | ScienceDirect Topics

Cylindrical Ball Mills differ usually in steel drum design (Fig. 2.11), which is lined inside by armor slabs that have dissimilar sizes and form a rough inside surface. Due to such juts, the impact force of falling balls is strengthened. The initial material is fed into the mill by a screw feeder located in a hollow trunnion; the ground product ...

Why the Limestone Ball Mill is widely used?

When the limestone ball mill is grinding the limestone, the motor drives the cylinder to run smoothly. The limestone will be transported to the hollow shaft by the feeder, and then directly into the cylinder body by following the hollow shaft. At this point, the limestone inside the cylinder will move along with the rotation of the cylinder.
