The Gyratory Crusher
The Gyratory crusher is one kind of cone crusher.IT is coarse crusher. Compared with the jaw crusher, its advantage is that the crushing process is carried out continuously in the circular crushing cavity with high capacity,low electricity consumption and stable working. It is suitable for crushing flaky materials. Gyratory crusher prefer to use in factories and quarries with large production capacity demand.
Primary crusher, the advantages is all the crushing program is a circle, so the production ratio is very high with lower power consumption, stable function and good for flakes.
From the final size distribution curve, in the composition of final materials, the bigger size than the outlet is much lower than that of jaw crusher.
The raw materials can be discharged by trucks, no need vibrating feeder.
Gyratory is perfect for large scale factory and quarries.
Working principle: The main components of the gyratory crusher are frame, fixed cone, movable cone, main shaft, large and small umbrella wheel and eccentric sleeve. The working principle is to use the spiral motion of the crushing cone in the cone cavity of the shell to make extrusion, splitting and bending to coarse crushing of ore or rocks of various hardnesses. The upper end of the main shaft equipped with the crushing cone is supported in the bushing in the middle of the beam, and the lower end is placed in the eccentric hole of the bushing. When the sleeve rotates, the crushing cone rotates around the center line of the machine, and its crushing action is continuous, so the working efficiency is higher than that of the jaw crusher. By the early 1970s, large gyratory crushers were able to process 5,000 tons of material per hour, with a maximum feed diameter of up to 2000 mm.
