= coarse ore hardness parameter which is used in primary and secondary crushing situations. It is defined by equation 8 with K. s. set to 55. K. 2 = 1.0 for all crushers operating in closed circuit with a classifying screen. If the crusher is in open circuit, eg pebble crusher in a AG/SAG circuit, K. 2. takes the value of 1.19. x. 1 = P. 80

Jan 01, 2016 Hence, a parameter v is introduced to represent the number of cycles of operation. As all cycles are assumed identical the general model given in Equation should, therefore, be modified as (11.32) P = X v • F where X = (I – C) • (I – B • C) –1. The method of evaluating a crusher model is illustrated in Example 11.2

The primary crusher is a 0.91 m X 0.51 m Pioneer jaw crusher. The crushed ore is transferred via conveyors to a 3-deck MCA vibrating screen with dimensions of 1.83- X 6.10-m per deck with the oversize from screening conveyed to a secondary 1.52-m Pioneer cone crusher, where the final product for milling is reduced to -95 mm

Jul 21, 2018 A vibrating screen was used to provide a mill discharge product separation at 19 mm ( in.). The minus 76 trail (-3 in.) plus 19 mm (+ in.) screen oversize product, which are the “pebbles”, were then crushed to essentially 100% minus 19 mm (- in.) in a crushing circuit. This product was returned to the feed end of the mill
