Mill roll material chute

Abstract

The invention provides a mill roll material chute. The mill roll material chute comprises guide material plates, camber plates, lateral material blocking plates, axial material blocking plates and rib plates, wherein a plurality of 1-shaped guide plates are welded on the backs of the camber plates of the material chute, and an angle theta3 of the guide plates and an end surface is equal to 120-160 degrees; the upper end face of the axial material blocking plate is fixed on the inner camber surface of the camber plates, the end face of the axial material blocking plate is fixed by the two lateral material blocking plates which are symmetrically arranged, the inner surfaces of the lower half parts of the lateral material blocking plates are connected with the axial material blocking plates through the rib plates; and an angle theta2 of the lateral material blocking plates is equal to 30-90 degrees, and an angle theta1 of the lower parts of the lateral material blocking plates and an end surface is equal to 15-60 degrees. The material chute is arranged on a flour mill region position composed of a compression roller and a cylinder body.

Description

technical field [0001] The invention relates to a horizontal roller mill, especially its distribution chute, which effectively solves the edge effect in the material extrusion process, improves the stability of the material bed in the grinding area of ​​the horizontal roller mill, and greatly improves the grinding efficiency of the horizontal roller mill. Background technique [0002] At present, the horizontal roller mill is widely used due to its advantages of high efficiency, energy saving and small footprint. Its working principle (see figure 1 ) means that after the material enters the horizontal roller mill, under the action of centrifugal force, the material rotates with the inner wall of the cylinder at a critical speed. After being scraped off by the scraping device, it falls onto the inclined distributing pan. Under the action of the distributing pan, the material moves forward for a certain distance and then falls to the inner wall of the cylinder again, and enter...

AI Technical Summary

Problems solved by technology

The following disadvantages exist in the grinding process of the horizontal roller mill: due to the instability of the material bed, the vibration of the equipment is large, the material has an edge effect when extruding, and a part of the material on the end surface of the shaft is squeezed out of the grinding area by the extrusion force of the material in the middle of the shaft , resulting in insufficient grinding of some materials and low efficiency of material grinding
