Surface finish (Also called sometimes surface roughness) is a numeric representation of a surface's "smoothness". There are 3 main ways to acquire the surface roughness value: Mechanical Scan: The most common method is to scan the surface with a needle that records the micro "Hills " and "valleys" along a linear section.

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

Introduction: Ball mills are widely used in the mining industry for grinding and crushing ores and rocks. They are designed with a rotating cylindrical chamber, where grinding media (balls) are added to grind the material. The charge volume of a ball mill is the total volume of grinding media (balls) and ore being processed inside

How do you calculate speed and feed? Speed (RPM) = (Surface Feet per Minute x ) / Diameter of the Tool. Feed Rate = RPM x Chip Load x Number of Teeth. RPM = Of the tool or workpiece. Chip Load = The amount of material removed, per revolution per cutting edge. Number of Teeth = The number of edges, facets, or flutes.
