Autogenous Grinding Process - SpringerLink

2023年7月24日  If the 30–80 mm pebble generated during autogenous grinding is used as the medium to crush the ore, the process is called pebble grinding. The density of pebble is less than that of steel ball, and its friction coefficient and contact area with the ground ore are greater than those of steel ball, so pebble grinding process has strong grinding force but weak impact force,
