Technical Field

The invention relates to the technical field of anti-blocking of a screen of a pulverizer, in particular to an anti-blocking device for a screen of a pulverizer.

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 pulverizer may be classified into a coarse pulverizer, a pulverizer, and an ultra-fine pulverizer according to the size of the pulverized or crushed material. 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 actual crushing process is usually several external forces acting simultaneously, but the high-end crushers are all tailored according to the crushing environment

Upon searching by the applicant at the time of the present invention, it was found that chinese patent discloses a "sizing screen for a pulverizing machine", which application No. is "201310040065.4", which includes the pulverizer including a pulverizing unit and a screen device. The arcuate screen defines a plurality of tracks of apertures extending in a cutting direction of the cutter.
