CE Certified XK-400 Rubber Open Mixing Mill Machine for Sheet Compounding

High-Efficiency Rubber Open Mixing Mill | Mixing Mill for Rubber, Silicone & Plastic | Qingdao Shun Cheong

Equipment Summary of mixing mill:

This Rubber Mixing Mill Machine (Two Roll Open Mixing Mill) is mainly used for mixing and kneading raw rubber, synthetic rubber, thermoplastics, or EVA with chemicals into final compounded materials. The finished material can then be fed to a calender, hot press, or other downstream processing machine for making rubber or plastic products.

Suitable for food-grade silicone, industrial silicone, and various rubber types including natural rubber (NR), nitrile rubber (NBR), and styrene-butadiene rubber (SBR). Working in conjunction with rubber/silicone vulcanizers, it enables production of a wide range of rubber- and silicone-based products.

Key Characteristics

Environmentally friendly, high-efficiency, and high-safety, with a human-oriented design that makes reloading and cleaning easy. The machine is recognized and trusted by factory labs, universities, and R&D institutions for recipe research and small-batch production.

Widely applied in the electric wire & cable, electronics, footwear/sole, sports equipment, and auto parts industries for rubber, plastic, and chemical mixing and plasticizing — as well as in reclaimed rubber factories, rubber product manufacturers, and cable factories.

Applications / Suitable Materials

Ideal for kneading and mixing: EVA, rubber, TPR, soles, rubber rollers, hoses, belts, sponges, vibration insulators, elastic cords, sealing materials, tires, tapes, master batches, pigments, inks, electric rubber parts, and various chemical compounds.

Working Principle

The machine features two hollow, precision-ground rollers rotating inward at different speeds. The front roller adjusts horizontally (manual or electric) to control the roller gap, while the rear roller remains fixed. Raw rubber or compound is drawn into the gap between the rollers and plasticized/mixed through strong shearing force. Also applicable for plastic processing.

Model Range

Available in multiple models from XK-160 to XK-710, differing in roller working diameter, roller length, front roller linear speed, speed ratio, maximum roller gap, batch capacity, motor power, and overall dimensions.

Example — XK-160: 160mm roller working diameter, 320mm working length, 8.95m/min front roller linear speed.
