Double Roller Shredder

Abstract

The invention discloses a double-roller shredding machine. The double-roller shredding machine comprises a machine box, a feeding hopper, knife rollers, a power mechanism and a control system; the machine box serves as a supporting body for the other components of the double-roller shredding machine; the knife rollers are arranged in a crushing cavity of the machine box; moving knife sets are arranged in a V-shaped staggered mode; the power mechanism drives the knife rollers to rotate in the crushing cavity so that the knife rollers can conduct shearing crushing on materials under matching of fixed knife sets; and the control system controls starting, stopping, the rotating speed and the like of the power mechanism. According to the double-roller shredding machine, electric energy consumption of per unit output can be effectively reduced, mechanical damage is reduced, and the equipment service life is prolonged; by arranging the two knife rollers and a material guide plate, the crushing productivity can be effectively improved, and the crushing efficiency is improved; knife holders can be separately disassembled to be replaced when abraded instead of replacing the whole knife rollers, and the maintenance cost is greatly reduced; moving knives and the knife holders as well as the knife holders and the knife rollers are connected mainly through shape matching, connection is fixed and firm, and the anti-shearing force is large; and blades can be exchanged and used for eight times, and the effective utilization rate of a knife material is greatly increased.

Description

technical field [0001] The invention relates to the technical field of material crushing equipment, in particular to a double-roller shredder. Background technique [0002] With the continuous improvement of the living standards of urban residents, the generation of domestic waste is also gradually increasing. Compared with the traditional direct incineration of waste, the unit calorific value of domestic waste RDF technology is higher. Domestic waste RDF technology needs to sort the waste for fine crushing, but the output of the traditional single-shaft shredder is low. To crush more than 5 tons of waste, the required equipment is very large, and the purchase cost is very high for users. In addition, the crushing work of the traditional single-shaft shredder is greatly affected by the composition of the material, especially when crushing easily entangled materials, it is easy to block and entangle the shaft, which will shorten the service life of the tool sharply, and the m...

AI Technical Summary

Problems solved by technology

After a period of crushing work of this kind of cutter, the screw is prone to loosening or wear, and the material is easy to block the screw hole, which brings great trouble to the disassembly and replacement of the movable cutter.

In addition, this kind of cutter head (moving knife) can be replaced less frequently, and expensive tool materials are not fully utilized
