The Standard Ball Bar (Dumbbell) The Standard Ball Bar (Dumbbell) is a gage device which is used to evaluate the overall performance of Coordinate Measuring Machines. The Ball Bar consists of two very precise spheres firmly attached to opposite ends of a rather long rigid bar.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

A ball mill is a drumgrinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.
Milling and grinding media are designed for ball milling and the grinding of bulk powder or granular materials into finer powder forms. Ceramic bead, hard metal shot, carbide balls, and other ballshaped media are used. The hardness of the powder or bulk material to grind determines the selection of ...
Flanges. Grinding machines shall be equipped with flanges in accordance with paragraph (c) of this section. (a)(4) Work rests. On offhand grinding machines, work rests shall be used to support the work. They shall be of rigid construction and designed to be adjustable to compensate for wheel wear.
Larger grinding media has a smaller grinding surface area, but offers a heavier weight that''s generally used to break larger ore. Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller. In some cases, we find ourselves adjusting the ball size by the millimeter to approach optimization.

Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material. In tower mills, there is no cascading action as in standard grinding mills. Stirred mills are also common for mixing quicklime (CaO) into a lime slurry.
