The system changes traditional multi-stage mixing into unistage type, which saves time, energy and space. It can be special designed for customer according to their productivity. 　Realizes continuous production, gets final mixed compound for one time, high automation and productivity; 　Reduces manual operation and decrease labor cost, the rubber quality is stable; 　Carbon black and ingredients are mixed more evenly, improves rubber tensile strength, abrasion resistance and fatigue resistance 　Reduces gas pollution, optimizes production environment and realizes green production.
