Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding or mixing materials like ores, chemicals, ceramic materials and paints.Ball 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.

Ball Mill: Operating principles, components, Uses ...

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.

High-Energy Ball Milling - an overview ScienceDirect Topics

High-energy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to high-energy collisions from the balls. High-energy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that cannot be made by conventional powder metallurgy methods.

Ball Mill VS Conche machine Chocolate Alchemy Forum ...

A ball mill will refine quickly, but really needs to be followed by a conche as it doesn& 39;t really conche much at all. I don& 39;t know this for sure, but I& 39;d assume you& 39;d have at least as much loss in a ball mill as you do in a stone grinder. The amount you& 39;re losing 300g seems really high to me, though. Are you scraping it clean at the end?
