Roller of roll type crusher

Abstract

The invention discloses a roller of a roll type crusher. The roller comprises a roller hole (1), a roller surface (2), large roll teeth (3), small roll teeth (4) and key grooves (5), wherein the roller hole is arranged at the center of the roller surface, and the large roll teeth and the small roll teeth are arranged on the outer edge of the roller surface; three key grooves are distributed in the roller hole, and the included angle between the adjacent key grooves is 120 degrees; three small roll teeth are arranged, the included angle between the adjacent small roll teeth is 120 degrees and the small roll teeth correspond to the key grooves in position; more large roll teeth are not uniformly distributed. The roller disclosed by the invention has the advantages that the large roll teeth are not uniformly distributed, three small roll teeth and three key grooves are correspondingly and uniformly distributed, the included angle between the adjacent small roll teeth or key grooves is 120 degrees, the arrangement of the three key grooves is beneficial to installation and angle adjustment of the equipment, and since only one key groove is used in installation and use, the roll teeth on the adjacent rollers are staggered mutually, so that the firmness for meshing the materials between the adjacent roller is improved and the crushing efficiency of clinkers is improved.

Description

technical field [0001] The invention relates to a roller crusher, in particular to a roller of the roller crusher. Background technique [0002] Roller crusher is suitable for cement, chemical industry, electric power, metallurgy, building materials, refractory materials and other industrial sectors, crushing materials with medium hardness, such as limestone, slag, coke, coal and other materials for medium and fine crushing operations. The toothed roller crusher mainly uses special wear-resistant toothed rollers to rotate at high speed to split and crush materials. [0003] The cement clinker roller crusher can be installed at the tail of the cement clinker cooler, or in the middle of the cooler. It is used for the crushing of cement clinker. After long-term operation of the rollers, some of the teeth of the rollers are worn out, and individual roller sleeves are cracked, which makes the broken particle size of the crushed clinker larger, which is not conducive to the produ...

Problems solved by technology

It is used for the crushing of cement clinker. After the long-term operation of the rollers, some of the teeth of the rollers will be worn out, and some roller sleeves will crack, which will make the broken particle size of the crushed clinker larger, which is not conducive to the production of the next process. In order to improve its The wear resistance and high temperature resistance of the roller accessories prolong the service life and reduce the production cost
