Jul 05, 2020 A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

Cone Mill | Conical Milling Machine For Size Reduction

Cone Mill | Conical Milling Machine For Size Reduction

Cone milling is one of the most common methods of milling in the pharmaceutical, food, chemical and associated industries. They are typically used for size reduction and deagglomeration or delumping of powders and granules.. Generally used for reducing material to a particle size as low as 180 m (80 mesh) a cone mill produces less dust and heat than alternative forms of milling.
