Pebble mills are used in preference to roller mills for pastes containing highly abrasive materials (e.g., silicates, iron oxides) or when the batches are relatively large. 3. Thinning and Tinting The thinning operation consists of adding the remaining quantities of oils, driers, thinners,
(0.25 in.) from the balance of the rock. The pebble rock is shipped as pebble product. The material that is larger than 0.85 mm (0.033 in.), or 20 mesh, and smaller than 14 mesh is separated using hydrocyclones and finer mesh screens and is added to the pebble product. The fraction smaller than 20 mesh is treated by 2-stage flotation.
type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage

Attrition mills use the hammermill principle to a certain extent; i.e., shattering by/impact. However, they also impart a shearing and cutting action. Grinding is done between two discs equipped with replaceable wearing surfaces. One or both of these discs is rotated; if both, they rotate in opposite directions.
