Roller tooth of crushing roller of biomass fuel crusher and manufacturing method of roller tooth

Abstract

The invention provides a roller tooth of a crushing roller of a biomass fuel crusher and a manufacturing method of the roller tooth, and relates to the field of crushing equipment. The roller tooth atleast contains Fe. The roller tooth further contains the following raw materials of, by weight, 2.5%-3.5% of Al2O3, 2%-3% of SiC, 1%-2% of Si3N4, 0.5%-0.8% of B4C, 0.05%-0.06% of polytetrafluoroethylene, 0.02%-0.03% of modified natural rubber, 0.02%-0.04% of bamboo charcoal fibers, 0.002%-0.008% of cullet, 0.006%-0.009% of modified bentonite and 0.8%-1.2% of epoxy anti-rust paint. The manufacturing method is completed through the following steps that raw materials are subjected to preheating treatment, inert gas is introduced, the cullet is subjected to processing, the materials are poured into a model and the formed roller tooth is coated with the epoxy anti-rust paint. According to the roller tooth of the crushing roller of the biomass fuel crusher and the manufacturing method of the roller tooth, abrasion of the roller tooth can be slower, rusting can be prevented, the service life of the crusher is prolonged, cost is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of pulverizing equipment, in particular to a crushing roller tooth of a biomass fuel pulverizer and a manufacturing method thereof. Background technique [0002] Biomass fuel refers to a new type of fuel that uses agricultural and forestry waste, such as straw, sawdust, bagasse, rice bran, etc. clean fuel. In order to facilitate transportation, these raw materials need to be bundled or pressed into blocks, and then crushed during factory processing. At present, the commonly used biomass fuel pulverizer has active crushing rollers and driven crushing rollers in the casing of the pulverizer. There are roller teeth distributed on the crushing roller and the driven crushing roller. Because the raw materials are not broken up when they enter the crushing process, the raw materials that are bundled or pressed into blocks fall on the driving and driven crushing rollers, causing the teeth of the driving and driven crushing ...

AI Technical Summary

Problems solved by technology

Because the raw materials are not broken up when they enter the crushing process, the raw materials that are bundled or pressed into blocks fall on the driving and driven crushing rollers, causing the teeth of the driving and driven crushing rollers to wear quickly, so that the pulverizer needs to replace the rollers frequently, and the cost Increase, slow down work efficiency
