Vertical shaft crusher with spirally arranged crushing space anvils

Abstract

The invention discloses a vertical shaft crusher with spirally arranged crushing space anvils. The vertical shaft crusher comprises a crushing space (1) of the vertical shaft crusher, wherein the anvils (2) are provided and spirally arranged in the crushing space (1); anvil inlets (3) are arranged at a spiral line entry point on top of the crushing space (1); and anvil propping outlets (4) are arranged at the spiral line entry point at the bottom of the crushing space (1). According to the vertical shaft crusher disclosed by the invention, the anvils mounted on the internal wall of the crushing space are spirally arranged; and anvil inlets and the anvil propping outlets are arranged on the crushing space, and thus when the worn anvils in the crushing space are to be replaced due to wear, anvils can be fed from the anvil inlets; the anvils in the crushing space are driven to spirally move by an anvil propping inlet device so as to replace the anvils; and the anvils can be replaced without stopping the machine and opening the top cover. Compared with existing replacing processes, the process disclosed by the invention is simpler, saves force and time, and improves the production efficiency.

Description

technical field [0001] The invention relates to a vertical shaft crusher in which the anvils in the crushing cavity are arranged in a spiral, and belongs to the technical field of vertical shaft crusher equipment. Background technique [0002] The vertical shaft crusher is the vertical impact crusher. The core part of the crushing is the rotor body. The shape of the rotor body is a hollow cylinder. , The lower plate and the distribution plate form each launching flow channel, and a throwing head made of special material is installed at the exit of the launching flow channel, and a crushing cavity is set on the periphery of the rotor, and an anvil that withstands impact is installed in the crushing cavity. When the material is sent into the rotor body by the distributor, the material enters different launching channels under the action of centrifugal force, and is accelerated to 60-75m / s speed to be ejected under the centrifugal force, and impacts the anvil in the vortex crus...

AI Technical Summary

Problems solved by technology

The existing anvils are horizontally attached to the inner wall of the crushing cavity, and there is only one group, which will gradually wear out during the impact process. When the anvils are worn to a certain extent, they must be shut down and opened for replacement, because the anvils are fragile. Parts, replacement frequency is high, so there is a problem of time-consuming and labor-intensive replacement, which affects production efficiency
