The rolling process is a metal forming process, in which stock of the material is passed between one or more pairs of rollers in order to reduce and to maintain the uniform thickness. This process is mainly focused on the cross-section of the ingot or the metal which is forming. Mainly by this process, we reduce the thickness of the metal ...

Ball burnishing creates a super finish often used when looking to produce a specific colour/luster on the surface of the workpiece. In this process, a hard ball is pressed against the workpiece surface. Materials that can benefit from burnishing The burnishing process is mostly carried out on soft metals such as aluminum, brass, zinc and plastics.

In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition.
