A multi-stage anti-damage roller press grinding device

Abstract

The invention relates to a multi-stage anti-damage roller pressing and grinding device. A plurality of slots are formed in a treatment roller, roller teeth are buried in the slots, springs and sleevesare arranged at the lower parts of the roller teeth, the roller teeth can retract into the slots under the action of larger external force, damage to the roller teeth due to too large external forceis avoided, and the roller teeth are protected. The treatment roller is divided into a plurality of different areas in the advancing direction of processing materials sequentially, each area comprisescorresponding slots, roller teeth as well as the sleeves and springs which are matched with the roller teeth, and the springs in different areas have different maximum elastic force. Besides, the springs with the different maximum elastic force can be replaced according to different treatment materials, so that the adaptability of the roller is also further improved.

Description

technical field

[0001] The invention relates to a material processing device, in particular to a multi-stage anti-damage roller grinding device. Background technique

[0002] The roller crushing device, especially the roller milling device, is a common and commonly used processing device for crushing materials. In the general processing process, the materials fed into the processing drum are paired by means of the teeth of the rollers arranged on the processing drum. The block is torn and beaten to crush or reduce the size of the block-like material.

[0003] The processing rollers in the roller processing device in the prior art are all non-adjustable rollers with fixed tooth shape and tooth height. Through research, it is found that the processing force of the processing roller on the material and the processing load on the roller teeth are related to the teeth of the roller teeth. The height has a direct relationship. If the tooth height of the roller teeth is larger, th...
