Attrition Mills

Attrition mills are classified as batch-, continuous-, or circulation-type mills. In the batch mill, material is fed into the jacketed chamber and is ground until the desired dispersion and particle size are achieved. Premixing is accomplished in the grinding chamber. Chamber walls are jacketed so that either hot or cold water can be circulated ...

Beneficiation of Gold and Silver Ores | SpringerLink

The IsaMill™ is a closed mill. Slurry travels through the mill in a "plug" -ow pattern through consecutive grinding disks. Media recirculates between the rotating disks distributing grinding action throughout the IsaMill™. Grinding is by attrition and abrasion of the particles in contact with the high-speed, small, circulating media.

Development of a combined hammer and attrition mill

Grinding is the term commonly used for the production of powered materials, it is associated with attrition mill. Attrition mill also called burr or plate mill consists essentially of two roughened plates, one stationary and the other rotating. The material is fed between the plates and the material is reduced by shear.
