Nesans CF Series Vertical Shaft Impact Crusher are high impact force, tertiary stage, high output ratio crushers. Uniquely designed to achieve the required product gradation for the production of m-sand. With dynamically balanced rotor design and robust rotor tips, CF Series Vertical Shaft Impact Crusher can save a huge on your maintenance costs.
Exclusive crushing chamber combined with exceptional metallurgy of the shaft can produce best results for a prolonged time. Statistical analysis of the performance of the machine have come to known to conform with its practical operation.
The autogenous “rock on rock” crushing technique results in several major advantages they are, product gradation remains constant, even as rotor wear parts wear; contamination rates are extremely low, as no wear parts are used to directly crush the rock; unbeatable product shape (extremely low flake and elongation values).
The material from the storage hopper should either be fed through a vibrating pan feeder or a belt feeder directly into the feed hopper of the VSI. The hopper is designed in such a way that it can store a small amount of material along its radius. The feed hopper is followed by a feed tube through a centre hole through which the material can reach the top of the spreader plate. The spreader plate is a safety mounting provided to protect the wear and tear of the rotor.
The feed tube directly connects itself to the centre of the rotor where it is protected by the spreader plate. This is where the particles hit the rotor for the first time. The rotor is designed with exhaust ports along its outer radius. The high speed of the rotor permits the particles to exit via the exhaust ports to enter the crushing chamber.
Crushing chamber is where the particles will spend the most of its time in the crusher. During the initial start of the crusher, and when the feed is given for the first time, particles build up along the outer space surrounding the rotor. This bed of particles will be where collision with other particles and most of the breakage will occur. The particles will fall down once they lose their kinetic energy through the empty shaft below the rotor into the output conveyor belt.
Vertical Shaft Impact Crushers are energy based crushers where crushing takes place by the magnitude of impact applied on the feed particles. The high speed of the rotor helps the particles to attain a necessary kinetic energy. When the particles travel along the outer space of the rotor and hit the previously build bed of particles, their kinetic energy is converted into potential energy. This is where the crushing happens. The rock breaks and the potential energy is stored in the rock which falls down due to gravity. The high impact force subjected on the particles breaks its sharp edges and reduces them into cubical form.
