Abrasion-proof plate of beater

The utility model relates to an abrasion-proof plate of a beater. The abrasion-proof plate comprises disc-shaped grinding plate, wherein the edge of the grinding plate is provided with four groups of grinding teeth; each group of grinding teeth comprises a long grinding tooth and a short grinding tooth; the long grinding teeth and the short grinding teeth are uniformly arranged at the circumferential edge of the grinding plate at intervals; the center of the grinding plate is provided with a shaft hole; a through hole is formed between the shaft hole and each group of grinding teeth; the grinding plate is made of high-chromium cast iron. The abrasion-proof plate of the beater has the advantages that the pulp circulation resistance in a rapid rotation process of the grinding plate is reduced, so that pulp is rapidly circulated; furthermore, the contact area of the pulp and the grinding plate is enlarged, so that the beating efficiency is improved, the production cost is lowered, the rigidity of the grinding plate is increased, the abrasive resistance of the grinding plate is good, and the service life of the grinding plate is prolonged from original once replacement within one month to once replacement within half a year.
