Crushing mechanism of single-tooth-roller crusher and single-tooth-roller crusher

Abstract

The invention discloses a crushing mechanism of a single-tooth-roller crusher and the single-tooth-roller crusher, and belongs to the technical field of crushing equipment. The crushing mechanism is characterized in that a plurality of groups of crushing teeth (6) are uniformly distributed in the axial direction of a main shaft (3), each group of crushing teeth (6) comprises a plurality of crushing teeth around the main shaft (3), the distance between every two adjacent groups of crushing teeth (6) is 320-340 mm, grid plates (5) are arranged on the lower side of the main shaft (3) and can rotate relative to the main shaft (3), and the grid plates (5) are arranged on the two sides of each group of crushing teeth (6) at intervals. According to the single-tooth-roller crusher, the number of groups of the crushing teeth is reduced under the condition that the length of the main shaft is constant, the crushing efficiency of the crushing mechanism cannot be influenced, and the production cost of the crushing mechanism is reduced. In addition, the gaps between the crushing teeth are enlarged, so that the crushing resistance in the middle of the main shaft is reduced, materials at the endof the main shaft are increased, abrasion of the crushing teeth is more uniform, and the utilization rate of the crushing teeth is improved.

Description

technical field [0001] A crushing mechanism of a single-toothed-roll crusher and the single-toothed-roll crusher belong to the technical field of crushing equipment. Background technique [0002] The crushing of sinter generally uses single-roll crushers, and shearing-type single-roll crushers are generally used in my country at present. It is mainly composed of main shaft, water pipe, fixed grate plate and transmission reduction mechanism. The grate plate is fixed and installed under the crusher, and the crushing teeth rotate in the gap between the grate plates. The broken tooth crown is made of heat-resistant and wear-resistant material surfacing or inserting blocks. The crushing teeth of the crusher cooperate with the grate plate to realize shearing crushing. The crushing teeth are usually installed on the main shaft and rotate with the main shaft. [0003] There are usually several groups of crushing teeth evenly distributed along the axial direction of the main shaft....

AI Technical Summary

Problems solved by technology

[0003] There are usually multiple groups of crushing teeth evenly distributed along the axial direction of the main shaft. Each group of crushing teeth includes multiple groups of crushing teeth evenly spaced around the main shaft. The distance between each connected two groups of crushing teeth is 280~310mm. The following problems exist during the use of the crusher: when two materials are fed into the crusher, usually there are more materials in the middle and less materials on both sides, which leads to serious wear of the crushing teeth in the middle of the main shaft, and wear and tear of the crushing teeth at both ends of the main shaft. Lightweight, low utilization rate of crushing teeth
