A similar type of intermediate crusher is the edge runner, which consists of a circular pan with two or more heavy wheels known as mullers rotating within it; material to be crushed is shoved underneath the wheels using attached plow blades. Pebble mill. A rotating drum causes friction and attrition between rock pebbles and ore particles.
The pebble crusher was reduced in size and the pebble bin capacity was increased to allow for a more consistent flow into the pebble crusher. Uncrushed pebbles were returned directly to the SAG mill, bypassing the pebble crusher, to further improve circuit efficiency.

Conventionally, crusher product was returned to SAG feed. Some designs, however, now allow pebble-crusher product to be returned to the SAG screens/discharge (allowing operation of the pebble crusher in closed circuit) or even to the ball-mill circuit. There is no 'right' answer for where the crusher product should be put of the time.
in the semi-autogenous grinding process by dynamically modeling the SAG mill-pebble crusher loop to improve the SAG mill throughput. Cleary [8–10] studied the e ect of rock particle shape on the dynamic filling and energy utilization in a SAG mill and analyzed the operation status of a SAG mill under di erent collision conditions through the ...

This paper examines the relations between the SAG mill and the pebble crusher in closed circuit while putting emphasis on controlling the pebble crusher in order to optimize the circuit throughput. Introduction. In the last few decades, significant efforts have been devoted to studying comminution circuits due to their high energy …
Pebble Crushing, or not. The choice of adding a pebble crusher to a circuit requires balancing the following: the ratio of rod mill to ball mill work index values; the desired transfer size of the grinding circuit (what is the model running at) energy efficiency of the grinding circuit; Ratio of work indices

b) Semi autogenous grinding in which the pebble fraction of mill discharge (+½ in.) is taken out through pebble ports for separate crushing and ball milling. The minus ½ in. fraction of mill discharge is recycled to the SAG mill through a classifier. The circuit is called SACB: Semi autogenous/ Crusher/Ball mill.
If the tumbling mill had to do the same amount of size reduction on the pebble crusher feed, its specific energy expenditure (W tm,pc ) would be: W tm,pc = Peb fr × S c × 1.19 × M ia × 4 ×
