The peripheral discharge type of Ball-Rod Mill is a modification of the grate type, and is recommended where a free gravity discharge is desired. It is particularly applicable when production of too many fine particles is detrimental and a quick pass through the mill is desired, and for dry grinding.

Ball end mills are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multi-dimensional contours in molds or dies. The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool. Because of the shapes required in these products it's common that multi axis machining

A dynamic and reliable steel ball, the intelligent design of this ball mill media is owed to our breakthrough technology, which enables us to take the finest chrome steel and vacuum-de-gas it. Because this process sets free all trapped air in the formulation, our chrome balls are produced with no air pockets—which results in a fully solid ...

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
