Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding ...

"A" - The standard size tolerance for the ball is ± .0001" (± .00254 mm) The roundness or sphericity of the ball is 25 millionths of an inch (.000635 mm) maximum. The surface finish of the ball is less than 1.5 microinches (38 NM) Ra. Finer Tolerance can be supplied on special order.
When one end wears out, switch to the opposite end for two times the life of a standard cobalt steel end mill. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as cast iron, hardened steel, titanium, and tool steel.

Ball Mills. Ball mills are industrial crushing tools that are characterized by their use of loose crushing media. Ball mills are just one of many size reduction equipment varieties. Ball mills, along with grinding mills, impact crushers and a variety of other equipment, are used for the reduction of all kinds of materials for all kinds of purposes.

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and ...
Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.
The ball blanks are cold headed, flashed and ground. They are then heated to 1700 °F in a very carbon-rich, gaseous environment to develop a high carbon case or shell in a rotary hearth furnace--carbon is literally cooked into the outer surface of the steel balls. After cooling, they are re-heated and oil or water quenched, depending on size.
A 45 degree face mill produces a much nicer finish than a 90 degree square shoulder face mill. Positive rake cutting geometries will typically require lower cutting forces (resulting in less deflection), and they will produce a finer surface finish.
Ball mills of greater length are termed "tube mills," and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as "pebble mills.'' In general, ball mills can be operated either wet or dry and are capable of producing products on the order of 100 um.
