XK-160 Two-Roll Rubber Mixing Mill | Open Mixing Mill for Rubber Compounding
The XK-160 two-roll rubber mixing mill is a premium industrial solution designed for efficient compounding of rubber and silicone materials. Engineered for precision, it processes food-grade silicone, industrial silicone, and various rubbers including natural rubber, nitrile rubber (NBR), and styrene-butadiene rubber (SBR). Seamlessly integrating with rubber/silicone vulcanizers, this mill enables production of diverse rubber-based and silicone products, serving reclaimed rubber plants, rubber product manufacturers, footwear factories, cable industries, and more.
- Rubber Recycling: Reclaiming and refining waste rubber
- Industrial Manufacturing: Producing seals, gaskets, and molded parts
- Footwear & Cable Sectors: Compounding materials for shoe soles and cable insulation
- Silicone Processing: Preparing food-grade and industrial silicone compounds
-
Model Versatility (XK-160 to XK-710):
- XK-160 Specs: 160mm roller diameter, 320mm working length, 8.95m/min front roller linear speed, 32:28 speed ratio, and 5kW motor power.
- Customizable parameters (roller gap, speed, and loading capacity) suit small-scale labs to large production lines.
-
Core Mechanism:
Two counter-rotating hollow rollers (front roller with manual/electric horizontal adjustment) generate strong shearing forces to plasticize or mix materials. Steam/water circulation through hollow rollers maintains precise temperature control (±2℃) for optimal compounding.
-
Premium Components:
- Rollers: Chilled alloy cast iron (HS 68-75 hardness), ground to a smooth finish for consistent mixing.
- Safety Systems:
- Electrical overload protection with auto-shutdown
- Safety fuse mechanism to prevent roller damage under extreme pressure
- Emergency brake lever for instant stop in hazardous situations
-
Adaptability & Efficiency:
- Processes diverse materials with adjustable roller gap (0.5-5mm) and speed ratio.
- Compact design with low noise (≤75dB) and optional PLC automation for precision control.
- Roller Material: Chilled Alloy Cast Iron
- Hardness: 68-75 HRC (roller surface), 65-70 HRC (gear)
- Cooling System: Water-circulated hollow rollers
- Control Modes: Manual operation / Automatic PLC control (optional)
- Reducer Options: Helical gear / Worm gear reducers
- Dimensions (XK-160): 1200×800×1300mm (L×W×H)
- Certifications: CE-compliant (optional ISO 9001)
- Multi-Material Compatibility: Handles natural/synthetic rubbers and silicone with equal efficiency.
- Safety-Centric Design: Triple protection systems (electrical, mechanical, emergency) meet international safety standards.
- Energy Efficiency: 15% lower power consumption than traditional models (verified by SGS report).
