Description

Wear-resistant curved tooth plate of crusher

Technical Field

The utility model relates to a rubbing crusher technical field particularly, relates to a rubbing crusher wear-resisting formula curved feed bar.

Background

A pulverizer is a machine that pulverizes a large-sized solid raw material to a desired size. The crusher consists of coarse crushing, fine crushing, wind conveying and other devices, and the purpose of the crusher is achieved in a high-speed impact mode. The wind energy is utilized to produce powder at one time, and the traditional screening procedure is cancelled. The method is mainly applied to various industries such as mines, building materials and the like.

The external force applied to the solid in the crushing process comprises four kinds of shearing, impacting, rolling and grinding. The shearing is mainly used for coarse crushing (crushing) and crushing operation, and is suitable for crushing or crushing operation of tough or fibrous materials and large materials; the impact is mainly used in the crushing operation and is suitable for crushing the brittle materials; the rolling is mainly used in high-fineness grinding (ultramicro grinding) operation and is suitable for ultramicro grinding operation of most of materials; the grinding is mainly used for ultramicro grinding or ultra-large grinding equipment and is suitable for further grinding operation after grinding operation.

The tooth plate of the crusher is an important part with high crushing efficiency, and the triangular teeth on the existing tooth plate are regular triangles, namely the two sides forming the triangle are equal in length. The main defects of the hammer type crusher which is commonly used at present are as follows: the tooth plate is usually made of cast iron materials, the top of the tooth bar is in a blunt arc structure, the tooth plate can only impact and crush materials, and has no cutting function, so that the efficiency is very low; secondly, the dental plate and the dental bar made of cast iron have good compressive strength and wear resistance, but poor toughness, and are easy to crack and break off particularly in the process of crushing hard materials such as ores, thereby causing equipment damage accidents.
