Roller refiner

Overview
This refining machine is designed for rubber processing and reclaimed rubber production. It integrates centrifugal composite casting rollers and an advanced peripheral drilling water-cooling system to control roller surface temperature and ensure consistent mixing quality.

Technical advantages

• Roller manufactured by centrifugal composite casting, offering improved wear resistance and higher strength compared with traditional static-cast rollers; service life reported >3× that of conventional rollers. Patent: 200920010357.2
• Peripheral drilling water-circulation cooling rapidly removes heat generated during rubber mixing, reducing roller surface temperature and improving reclaimed rubber quality.
• Due to the peripheral drilling cooling the equipment achieves high linear speed (up to 75 m/min for the rear roller), lowering energy consumption per unit output and increasing throughput.
• Modular equipment structure simplifies maintenance and repair operations.
• Product recognized by industry evaluations and awards (Dalian brand product 2011; scientific and technological achievement appraisal by China Federation of Logistics and Purchasing at international advanced level; third prize Science and Technology Progress Award, China Federation of Logistics and Purchasing 2012; Golden Bridge Award, Ministry of Science and Technology 2014).
