High pressure grinding rollers comprise two rolls mounted in a robust frame. One roll is permitted to float on rails and is positioned using pneumo-hydraulic springs, while the additional is fixed in the frame. The feed is launched to the gap between the rolls and is crushers by the mechanism of antiparticle breakage.
Fig. 1 depicts the high-pressure grinding rolls (HPGR) crushing process and key variables. The equipment comprises two rolls rotating in opposite directions. One of them, the fixed roll, cannot move sideways. The other one, the floating roll, has its frame attached to a hydraulic system, and thus its position can vary along the x axis depending on the extension of …
Typical hard-rock crushers like jaw, gyratory and cones break rock by nipping the ore between a fixed/stationary and a moveable wear-resistant surface/liner. How much reduction each crushing stage is capable of infliction of rocks (reduction ratio) is driven by the angles between the 2 surfaces on each side and holding the rocks-to-be-crushed ...
Rutter's ore-crusher (Fig. 9), patented in 1869, consisted of a cone attached to a square shaft working inside an open cylinder, with a ball-and-socket joint supporting the upper end of the shaft and an eccentric wheel rotating in the base-plate, which gyrated the spindle carrying the crushing-head in a conical orbit about the true axis of ...
