A vertical shaft impact crusher (also named a VSI crusher) is a machine that breaks stone and rock materials by applying vertical shaft impact force. In the Chinese machinery market, there are many models and types of impact crushers.
VSI Impact Crusher:
A VSI impact crusher is a specific type of impact stone crushing machine. It uses impact force to break materials by driving the shaft and the rotor, which launch the rocks and stones at high speed against the walls. This will create wild grinding and strife, which finally break the materials into smaller pieces. The smaller pieces will then fall down to be shaped and crushed further by the machine again. VSI impact crushers are usually used in artificial sand production lines, stone shaping, and fine crushing.
VSI5X Impact Crusher:
The VSI5X impact crusher is an improved version of the original VSI impact crusher. It has a larger throughput and better finely crushing effect. The main differences between the VSI5X impact crusher and the original one are that the new version adopts a more excellent and advanced rotor. The rotor now has five symmetrical axes, which ensure high speed and give the machine extra strength. In addition, the VSI5X impact crusher has modernized crushing cavities, which can shape and crush materials into various sizes, even better than the old versions. Finally, the VSI5X impact also added the motor control system, which ensures that the machine works steadily and reliably over long periods. With all these improvements, the VSI5X impact crusher has become a more excellent choice for users in fields such as mining, building materials, and industrial production.
RK impact Crusher:
The RK impact crusher is a unique type of machine that is often used to crush stones and rocks with high hardness and abrasiveness, like basalt and granite. It uses two rotors that rotate in opposite directions to form a crushing zone between them. Materials are then fed into the upper rotor, where they are flung outwards into the lower one. This repeated process breaks the stuff into smaller parts. One of the primary advantages of the RK impact crusher is its capacity to produce excellent sand with good particle forms. Also, with its twin-rotor design, it possesses higher efficiency and output than traditional single-rotor crushers.
