XK-400 Model Rubber Mixing Mill with 1000mm Working Length and 37KW Motor Power for Efficient Rubber Processing
This advanced rubber mixing mill comprises several precision components including the Base, Rack, Gland, Rollers, Bearings, Transmission device, Lubrication device, Decelerator, Roller temperature adjustment device, Emergency shutdown device, and brake rigging.
Designed for processing a wide range of rubber materials including:
- Food-grade silicone rubber
- Industrial silicone rubber
- Solid silicone rubber
- Natural rubber
- Nitrile rubber (MBR)
- Styrene-butadiene rubber (SBR)
- Reclaimed rubber
- Butyl rubber
- Ethylene propylene diene monomer rubber (EPDM)
- Neoprene
- General-purpose rubber
- Polyurethane rubber (PUR)
- Acrylate rubber (ACM)
- Cis-butadiene rubber (BR)
- Polysulfide rubber
- Silicone rubber
- Fluororubber
- Chlorosulfonated polyethylene rubber
The open mill equipment can be used in conjunction with rubber and silicone vulcanizing machine equipment to vulcanize various rubber and silicone products.
The main working components consist of two hollow or drilled rollers rotating inwards in opposite directions. The front roller (operator side) can be moved horizontally back and forth manually or electrically to adjust the roller gap, while the rear roller remains fixed. Both rollers are typically the same size but rotate at different speeds, creating strong shearing action for effective plasticizing or mixing.
Rollers are manufactured from LTG-H safety chilled cast iron with surface hardness of HS 68-75, featuring smooth ground surfaces. The hollow rollers allow for steam or cooling water circulation to precisely adjust temperature according to processing requirements.
