　　During the use of the crusher parts, the metal surface of the crusher is subjected to the chemical and electrochemical action of the surrounding medium and also to the action of friction or impact. The damage to the equipment parts caused by these actions is c ed corrosion wear.

　　The corrosion and wear of crusher parts brings harm to the crusher equipment. The damage to the equipment parts is quite serious. The harm of corrosion and wear is not only the loss of parts, but also the damage to the structure of the crusher equipment. In the production of scrap and equipment accidents, this wear and tear sometimes even limits the possibility of adopting the process and equipment.

　　Corrosion and wear of metals are divided into two forms according to the principle of corrosion; one is electrochemical corrosion, which is due to the effect of electrolyte, and local current is generated; the other is chemical corrosion, which is due to the action of dry gas or non-conductive liquid medium the result of. The damage rate of metals caused by electrochemical corrosion is faster, and the serious damage caused by corrosion and wear is *ly caused by electrochemical corrosion, and the rate of damage to metals by chemical corrosion is relatively slow.

　　In order to prevent corrosion and wear, it is better to use anti-corrosion oys, stainless steel, etc. as materials for manufacturing parts, and use carbon products as corrosion-resistant materials. From an economic and technical point of view, it is often used to add a gold or non-met ic protective layer on the surface of the part, such as zinc, chromium, nickel, tin, copper, aluminum, lead by hot dip, electroplating or metal spraying. Such as metal materials are compounded on the metal surface, or paint (paint, varnish, mineral oil, petroleum jelly, paraffin solution, etc.) is applied on the surface of the parts as an anti-corrosion layer.
