Vertical offcenter crusher and its operation method

Abstract

The present invention provides a vertical centrifugal crusher and an operating method thereof. Wherein, the vertical centrifugal crusher is provided with a crusher body and a rotary body comprising a first and a second material projecting mechanisms. The first material projecting mechanism comprises a first crusher layer forming plate for forming a first crusher layer which can project the crusher material filled into the inside of the crusher body through the material filling port from the surface to radial outside by centrifugal force . The second material projecting mechanism is arranged at the rotary center farther than the first material projecting mechanism and crushes the collided crusher material at the position that the crusher material projected by the first material projecting mechanism is collided, and projects the crusher material by the centrifugal force from the surface to the radial outside and thereby discharges the crusher material through the material projecting port. Therefore, the multitime crush or complete grain effects can be obtained by making the crusher material pass through the rotary body one time.

Description

technical field [0001] The present invention relates to the improvement of a vertical centrifugal crusher and its operation method, and more specifically relates to a machine which, although the structure is simple, can achieve the effect of crushing and sizing multiple times by allowing crushed raw materials to pass through the rotating body once, and the productivity of crushed products is high. A vertical centrifugal crusher and its operating method. Background technique [0002] A typical conventional example will be described below as a vertical centrifugal crusher that crushes the crushed raw materials by projecting the crushed raw materials in the horizontal direction and colliding with the impact surface of the crushed material layer. [0003] The centrifugal sizing device of conventional examples 1 and 2 (hereinafter referred to as vertical centrifugal crusher) uses the centrifugal force generated by the rotation of the rotor (rotary body) to throw (project) the mat...

AI Technical Summary

Problems solved by technology

Since the projection speed of the crushed raw materials affects the discharge speed of the crushed raw materials after they collide with the impact surface, when the projected speed of the crushed raw materials is slow, the retention of the crushed raw materials on the impact surface increases, which will prevent the projected crushed raw materials from going directly to the impact surface. Collision, so can not apply a strong impact on a large number of broken raw materials

That is, there is a problem that effective crushing cannot be performed when a large amount of crushed raw material is supplied, and the crushing capacity is reduced.
