Addition of pebbles to a ball-mill to improve grinding ...

A recycle pebble crusher is often used to crush some of these 'critical size' pebbles, as a means of controlling the level in the primary mill. Rather than expending energy on crushing these pebbles, they can be put to good use in secondary mill(s).

Optimise your pebble crushing with HPGR

Whether recirculated through primary milling or separated and sent to a dedicated downstream pebble mill, pebble crushing is an energy-intensive operation that ties up a site's limited resources. With their high throughput and capacity for dealing with competent ores, High Pressure Grinding Rolls (HPGR) make ideal pebble crushers.

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.
