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

2021-9-26  Initial tests were done using pebbles from previous tests on gold ore, in combination with balls, to mill silica sand (0.6-1.5mm). The size distributions of the balls and the pebbles were calculated to simulate steady-state addition of balls (37.5 mm) and partly-rounded pebbles (19-75 mm).

INVESTIGATION OF SORTING TECHNOLOGY TO

2018-2-20  Autogenous mill, pebbles, ore sorting INTRODUCTION A well known natural phenomenon in autogenous (AG) mills is the build-up of pebbles. These pebbles are typically called “critical size material” and occupy a large volume of the mill and thus reduce the capacity for new material to be processed.

Ball Mill - an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
