Millstone-type hammer crusher

Abstract

The utility model discloses a millstone-type hammer crusher. The millstone-type hammer crusher comprises a feeding hole, a hammer, a rotor, a sieve, a sieve pressing frame, a discharge hole, a crusher body and a motor, as well as a millstone frame and a millstone arranged on the millstone frame. When being fed, the material is crushed not only by a hammer-sieve clearance between the hammer and the sieve of the crusher but also by crushing effect generated by the hammer-millstone clearance between the hammer and the millstone. After the hammer-sieve clearance becomes larger, the hammer-millstone clearance still plays a crushing role, the higher crushing efficiency can be still kept, and the average output of the crusher can be increased. Due to the existence of the millstone, the rotating friction resistance of the material is increased, a thicker hammer can be adopted and the lateral surface of the hammer is made to generate friction with the millstone, so as to increase the available working area of the hammer, and greatly prolong the service life of the hammer.

Description

technical field [0001] The invention relates to a crushing equipment used in feed, food, chemical industry, medical treatment and other industries, in particular to a disc-type hammer mill. Background technique [0002] The hammer mill is usually composed of a feed inlet, a body, a rotor, a hammer, a sieve, a screen press frame, a motor, and a discharge port. When working, the motor drives the rotor to rotate the hammer on the rotor, and the material After entering from the feed port, it is continuously hammered by the hammer and crushed. The crushed material powder passes through the sieve hole and is discharged from the discharge port of the pulverizer. The pulverizer in the prior art mainly has the following problems: [0003] 1. After the material enters from the feed port of the pulverizer, it depends on the gap between the hammer and the screen of the pulverizer to pulverize the material. When the hammer and the screen of the pulverizer are new, the gap between the ham...

Problems solved by technology

[0003] 1. After the material enters from the feed port of the pulverizer, it depends on the gap between the hammer and the screen of the pulverizer to pulverize the material. When the hammer and the screen of the pulverizer are new, the gap between the hammer and the screen is adjusted to an appropriate level. The position of the pulverizer is high, but with the wear of the hammer, the gap between the hammer and the screen increases, and the output of the pulverizer gradually decreases. When the output of the pulverizer is about 60%, the hammer must be replaced, so the pulverizer The actual average output is often about 80% of the rated output

[0004] 2. Judging from the worn hammer, the wear of the hammer is usually at the front end of the hammer, about 20-40mm, while the middle and rear ends of the hammer are basically not worn or worn very little, and there are often many worn out hammers Some are not fully utilized, resulting in high cost of using the pulverizer

[0005] For a long time, the above problems have been the key problems that plague the further improvement of pulverizer technology
