Abstract

The invention discloses a special rotation cutter for a pulverizer. The special rotation cutter comprises a cutter shaft, a left protection plate, a right protection plate, a cutter head and a stable shaft. The end portions of the cutter shaft penetrate the center position of the left protection plate and the center position of the right protection plate correspondingly and are embedded in a left shaft head arranged on the side face of the left protection plate and a right shaft head arranged on the side face of the right protection plate. According to the special rotation cutter for the pulverizer, hammers, made of alloy materials, of equipment can effectively crush large to-be-pulverized objects entering a pulverizing chamber firstly, and then the fine pulverizing efficiency is further improved; meanwhile, upper curve blades and lower curve blades can pulverize the to-be-pulverized objects on the side face of the cutter head in the cutter head rotation process; meanwhile, the edge of the cutter head is sharp, the fine pulverizing efficiency is greatly improved, the pulverizing time is greatly shortened, and the noise of the cutter head is lowered to a certain degree; and the production efficiency is effectively improved, and wide application prospects are achieved in future.

Description

technical field [0001] The invention relates to the technical field of pulverizers, in particular to a special rotary knife for pulverizers. Background technique [0002] A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. The pulverizer is composed of coarse crushing, fine crushing, wind conveying and other devices, and achieves the purpose of pulverizing in the form of high-speed impact. Using wind energy to form powder at one time, canceling the traditional screening procedure. It is mainly used in various industries such as mines and building materials. There are four types of external forces applied to solids during the pulverization process: shearing, impact, rolling, and grinding. A good pulverizer rotary knife is an important part of the pulverizer. [0003] The existing rotary knives dedicated to pulverizers have the following deficiencies: firstly, large materials cannot be crushed first; secondly, only the materials at the...
