Requirements for material properties of Open mixing rolls

Requirements for material properties of Open mixing rolls
1. it should have certain mechanical strength and rigidity, and be able to withstand the force of the rubber material;
2. the working surface of the rollers should have high abrasion and corrosion resistance, and the surface hardness should not be less than 65° Shore;
3. Very high requirements for surface finish, so as to facilitate cleaning or degumming, etc;


4. Concentricity of the rollers, true roundness of the precision requirements are very high, will affect the uniformity of the thin and thick rubber products;
5. from the structure, with reasonable geometry, to prevent excessive stress concentration;
6. good thermal conductivity, easy to heat and cool the rubber material.
