Diameter 2 Ball Mill

Ball Mill - an overview | ScienceDirect Topics

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 mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Industrial Ball Mills: Steel Ball Mills and Lined

Steel Ball Mills & Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods), the product to be ground is added and the cylinder

Ball Mills - 911 Metallurgist

If finer grinding is wanted two or three stage grinding is advisable as for instant primary rod mill with 75—100 mm (3″—4″) rods, secondary ball mill with 25—40 mm(1″—1½") balls and possibly tertiary ball mill with 20 mm (¾") balls or cylpebs. To obtain a close size distribution in the fine range the specific surface of the grinding media should be as high as possible. Thus as small balls as possible should be

Practical 1 : Ball Milling | TF Lab 1

23.12.2013· In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length
