Steel dental plate crusher and manufacture method thereof

Abstract

The invention relates to a steel dental plate crusher. The crusher is mainly characterized in that either a main dental plate or an auxiliary dental plate comprises an arc substrate and a plurality of fixed blades connected with the arc substrate into a whole, the arc substrate and the fixed blades are made of low-carbon steel castings or sheet welding parts. The crusher changes the single knock crush of the prior art into knocking and cutting combination type crush, by improving the dental plate material and the manufacture process thereby ensuring that the production efficiency is greatly improved, being capable of reducing the consumption of raw materials and power and prolonging the service life of the crusher. The crusher is suitable for crushing and processing feed, straw, crops, medicines, ore, and the like.

Description

technical field [0001] The invention belongs to the technical field of material crushing equipment, in particular to a steel tooth plate grinder and a manufacturing method thereof. Background technique [0002] In the known material crushing technology, the commonly used hammer-type feed mill, the structure of the crushing part is composed of a shell, a tooth plate, a turntable and a movable blade connected to the turntable through a pin shaft, through which the movable blade rotates. Inertial knocking achieves material crushing. However, the main defects of the commonly used hammer feed mills are: [0003] 1) The tooth plate is usually made of cast iron, and the top of the tooth bar is a blunt arc-shaped structure, which can only impact and crush the material, but has no cutting function, especially when crushing fibrous materials such as straw and medicinal materials, the efficiency is very low; Secondly, although the tooth plates and tooth bars of cast iron materials ha...

AI Technical Summary

Problems solved by technology

[0003] 1) The tooth plate is usually made of cast iron, and the top of the tooth bar is a blunt arc-shaped structure, which can only impact and crush the material, but has no cutting function, especially when crushing fibrous materials such as straw and medicinal materials, the efficiency is very low; Secondly, although the tooth plate and tooth bar made of cast iron have good compressive strength and wear resistance, their toughness is very poor, especially in the crushing of ore-like hard materials, they are easy to break and break off, which will cause equipment damage accidents.

[0004] 2) In order to ensure sufficient strength and toughness, the movable blade and pin shaft are made of low-carbon steel, and the thickness of the movable blade is more than 5mm. The disadvantages brought about by this are that the rotating component is too heavy, resulting in a large consumption of rotating power , high energy consumption; second, the movable blade and the pin shaft have poor wear resistance, are easy to wear, have a short service life, and are frequently replaced, resulting in material waste and low production efficiency; third, the movable blade is too blunt and can only break block brittle materials. Difficult to crush fibrous tough materials
