Gyratory 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 …

Tips to maximize crushing efficiency
Cone and gyratory crusher considerations. Make sure the cone crusher does not get ring bounce or chatter. Variable flow controlled by level sensors will ensure consistent feeding and maintain a full crushing chamber. Low oil temperature should prevent operation of the unit. High oil temperature should stop the crusher feed and allow the unit to ...
Caring for your cone crusher: A guide to optimising performance
A cone crusher punishes itself in every minute of operation. It squeezes a dense mass between heavy castings until the mass disintegrates. It abrades and minces aggregate until the material yields to the applied forces. It rumbles and vibrates and bangs as its core shaft spins eccentrically to capture and reduce chunks of aggregate.
AMIT 135: Lesson 5 Crushing – Mining Mill Operator Training
Cone Crushers. Originally designed and developed by (1920). Similar to gyratory except the spindle is supported at the bottom of the gyrating cone instead of being suspended. The head to depth ratio is larger than gyratory crushers. Cone angle are flatter and the slope of the mantle and concaves are parallel.
Reduction Ratio Calculator
This means that the crusher has reduced the size of the material by a factor of 5. A higher reduction ratio indicates a more efficient crushing process, as it signifies a greater reduction in size. This is often desirable in the aggregate and mining industries, where reducing the size of the material enables easier handling, transport, and ...
