Rock Crushing Rule of Thumb Mineral Processing & Metallurgy
calculations define the efficiency of a fine stagecrush ball mill circuit as 10 to 12 depending on ball mill feed size, and some SABC (SAG/ball mill/pebble crusher) circuits operating with an efficiency of 1314 or higher on coarse feedFull Scale Test Circuit Based upon the results of the pilot plant test work, a decision was made to conduct a full scale test in 1990 utilizing one of the ten (10) primary mill lines at the National Steel Pellet Plant Primary Mill Line No 10 would be converted to a fully autogenous grinding mill with pebble extraction and crushing Engineering and installation of the test circuit wasPebble Crushing in SAG Mill Circuit
Grinding Circuit an overview | ScienceDirect Topics
The SAG mill was designed to treat 2,065 t h −1 of ore at a ball charge of 8% volume, total filling of 25% volume, and an operating mill speed of 74% of critical The mill is fitted with 80 mm grates with total grate open area of 766 m 2 ( Hart et al, 2001 )Choke feeding of a gyratory crusher has been claimed beneficial when the crusher is followed by SAG mills, as their throughput is sensitive to the mill feed size (Simkus and Dance, 1998) Operating crushers under choke feeding conditions gives more even wear and longer crusher lifeGyratory Crusher an overview | ScienceDirect Topics

The pebble stockpile material is fed to one or both of the cone crushers which discharge onto the SAG feed belt The SAG trommel undersize flows into a common sump shar ed with the ball millSince there are not that many small SAG mill operations of under 2000 TPD, and most sub2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <15″Crushing in Mineral Processing

Crusher Wikipedia
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiatedTable Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl linerGyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface As the gap between the bowl liner and the mantle narrows, the rock isHow it Works: Crushers, Grinding Mills and Pulverizers
