achieve the desired size reduction. Gyratory crushers, jaw crushers, roll crushers, and impact mills are used for primary and secondary crushing. After crushing, the size of the material is further reduced to 50 micrometers ( m) or smaller by grinding, using smooth rolls

create more environmental friendly quarry operations. Two major issues in quarry operations are: 1. Energy Wastage due to inefficient flowsheet development of the quarry processing operations 2. Generation of fines from crushing (nominally -4 mm) which cannot be utilised and sold. These sometimes have to be stored and stockpiled on site

Feb 17, 2016 Gyratory Crushers. The primary rock breaker most commonly used in large plants is the gyratory crusher, of which a typical section is shown in Fig. 5. It consists essentially of a gyrating crushing head (521) working inside a crushing bowl (522) which is fixed to the frame (501)

Possible failure modes related to: 1) Lubrication -- gears and bearings. 2) Hydraulics -- controls. 3) Assembly -- tolerances, fit and tightness. 4) Installation -- fastener correct strength and torque. 5) Design -- structural natural frequency 5) (foundation and supports) 6) Foreign metal object entered crusher

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are
