a certain crusher accept a feed of rock having diameter of 0.75 in

To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Also, primary gyratories require quite a massive foundation. Primary crushing with impact crushers. The primary impact crusher offers high capacity and is designed to accept large feed sizes

    Mar 11, 2016 Rittinger’s theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it: “The work done in crushing is proportional to the surface exposed by the operation; or, better expressed for this purpose, the work done on a given mass of rock is proportional to the reciprocal of the

    The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:

    For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7 1.7 = 78 cm
