The new roller assembly description: The new roller assembly, changing the traditional formal structure, using a variety of sealing means, excluding the veterans into the oil spill, into dust, three different heart defects. Several major advantages of the new assembly: 1, no leakage, no one group of fuel, only three to one days once a small amount of additional oil. 2, the high degree of sealing, easy assembly within the production process into the dust, thus extending bearing life. 3, in the production process according to the degree of wear of the bearing assembly, adjustable bearing clearance, the upper and lower bearings to ensure concentric Raymond, bearings can be used continuously for more than ten months. 4, the new roller assembly to extend the maintenance cycle, reducing maintenance strength, reduce production costs and improve production efficiency, can bring considerable economic benefits to the user. 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 and after normalizing heat treatment, to further enhance the mechanical properties of Raymond, making the product not only good wear resistance, and toughness is further improved. 2, Mn13, compared with Mn65, Raymond mill ring after casting material using Mn13 Raymond 3r, the durability is also improved. This product has been casting after pouring water toughening treatment, the water treatment tough casting has high tensile strength, toughness, ductility and non-magnetic, making more durable Raymond Raymond grinding ring profile, the use of which is subject to severe impact and when a strong pressure deformation, surface hardening, and the formation of martensite, thereby forming a high wear resistant surface layer and inner layer maintaining excellent toughness, even if worn to thin, but also can withstand a greater impact load .
