Crushed material grinding device with built-in crushed material cutters

Abstract

The invention provides an improved crushed material grinding device with built-in crushed material cutters. The device comprises a case, a crushed material roller and a grinding roller, wherein the crushed material roller is arranged at the upper end of the inner part of the case while the grinding roller is arranged at the lower end of the inner part of the case, and an axial direction of the crushed material roller is perpendicular to that of the grinding roller; the crushed material roller comprises semi-cylinders hinged with the two side walls, the same semi-cylinders are controlled by a switch to open or close, and a plurality of bulged crushed material cutters are arranged on the inner wall of the crushed material roller and are arrayed in a spiral form on the inner wall of the crushed material roller. The crushed material roller of the invention comprises the semi-cylinders hinged with the two side walls, and the crushed material cutters are arranged on the inner wall of the crushed material roller, so that the materials can be rotated in the crushed material roller and can be repeatedly crushed, and the crushing effect of hard materials is more thoroughly achieved; meanwhile, the materials are crushed in the closed crushed material roller so as to effectively avoid the phenomenon that when the collision of the crushed material cutters which run at high speed and the hard materials occurs, the hard materials are flied out of a charging opening to result in safety accident.

Description

technical field [0001] The invention relates to the field of grinding equipment, in particular to a grinding device for grinding materials with a built-in grinding knife. Background technique [0002] In the production process of bricks or cement, some materials with large particles need to be crushed before use. Otherwise, materials with too large particles will easily cause problems such as uneven density of bricks. Although common pulverizers can also crush hard materials into smaller Small particles, but because the crushing knife is set on the outer wall of the crushing drum, it cannot be crushed repeatedly, and the overall crushing effect is not good. At the same time, when the high-speed external crushing knife collides with hard materials, Hard materials often fly out from the feed port, which is likely to cause unpredictable safety accidents. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings and deficiencies in...
