Dynamic Modeling and Simulation of SAG Mill Circuits with Pebble Crushing
(SAG) mills are often used for primary grinding. However, the breakage mechanism of an AG/SAG mill is inefficient in grinding particles of a certain size, typically in the range of 25-55 mm, i.e., pebbles. Therefore, cone crushers are often used as pebble crushers and integrated

Pebble Mill Grinding
Pebble Mill Grinding. Essentially tube mills and pebble mills may be considered as ball mills, the basic difference being that the ratio of length to diameter is greater. Usually the shell length is between 2 and 5 times the diameter. These mills are primarily used to grind various materials to 100 mesh and finer.

How to choose the correct pebble crusher for your site
Pebble crushing is very topical: as we dig deeper into mines, the ore is getting harder and ore grades are declining, causing the build-up of pebbles in mills to become a greater concern. If pebbles are not dealt with appropriately, they start to occupy a large part of the mill and reduce its processing capacity.
