The density of forged steel balls is generally taken as 7.85, while cast steel balls are taken as 7.4. Forged steel has a higher density than cast iron, so it is important not to use a single formula for both:
A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
