Raymond supporting the jaw crusher used in varying degrees of wear and cutting wear influence, the use of materials that require high toughness and high hardness, it is known that the hardness and toughness is a contradiction. Impact wear, and gradually dominated the latter part of the wash and wear and micro-cutting. Broken material hardness of the material block, block the greater the toughness requirements, the higher the hardness of the material, the higher the hardness of the hammer material requirements. Many people often rely on aspects of the lubricant to overcome friction, avoiding Raymond mill parts and machinery, but all things are good and bad, lubrication failure of harm is very large. Raymond grinding ring: Normally we see Raymond grinding ring has the following two materials: 1, Mn65, Raymond grinding ring in the use of this material, its durability has significantly improved, the product is characterized by high hardness, wear resistance, and magnetic. The main need for the product in addition to iron powder processing field, the product after normalizing heat treatment and Raymond Plant, to further enhance the mechanical properties, making the product not only good wear resistance and toughness are further improved. 2, Mn13, compared with Mn65, Raymond grinding ring after the adoption of the Mn13 casting material, but also on the durability of the change. This product is carried out after casting pouring water toughening treatment, castings have high tensile strength, toughness, ductility and toughness nonmagnetic water after treatment, making the ring more durable Raymond Raymond mill, in the use of which is subject to severe shocks and When a strong pressure deformation, surface hardening, and martensite formed 5r Raymond, thereby forming a high wear resistant surface layer Raymond 6r, maintaining excellent toughness while the inner layer, even if worn to thin, but also can withstand greater impact loads. 5r Raymond, Yuxin Senda (certified), Heyuan Raymond Ltd provided by Henan new Senda Heavy machine.
