Construction
This machine comprises several components, including the Base, Rack, Gland, Rollers, Bearings, Transmission device, Lubrication device, Decelerator, Roller temperature adjustment device, Emergency shutdown device, and brake rigging, among others.
Applicable mixing range:
refining food-grade silicone rubber, industrial silicone rubber, solid silicone rubber, refining rubber types, natural rubber, nitrile rubber (MBR), natural rubber, styrene-butadiene rubber (SBR), reclaimed rubber, butyl rubber, natural rubber, ethylene propylene diene monomer rubber (EPDM), neoprene, general-purpose rubber, polyurethane rubber (PUR),acrylate rubber.
(ACM), cis - butadiene rubber (BR), butyl rubber, polysulfide rubber, silicone rubber, fluororubber, chlorosulfonated polyethylene rubber.The open mill equipment can be used in conjunction with rubber and silicone vulcanizing machine equipment according to product requirements to vulcanize various rubber products and silicone products.
Structure:
The main working parts are two hollow or drilled rollers rotating inwards in opposite directions. The roller on the operator's side is called the front roller, which can be moved horizontally back and forth manually or electrically to adjust the roller gap to meet the operational requirements. The rear roller is fixed and cannot move back and forth. Generally, the two rollers are of the same size and rotate relative to each other at different speeds. As the rollers turn, the raw rubber or rubber compound is drawn into the gap between the two rollers. Under the strong shearing action, the purpose of plasticizing or mixing is achieved.The open mill is also used in the plastic processing and other sectors.
The rollers are made of LTG - H safety chilled cast iron. Their surface hardness is HS 68 - 75, and they have smooth surfaces formed through grinding. The rollers are hollow inside. According to usage requirements, steam or cooling water can be introduced to adjust the temperature of the rollers. The two rollers rotate relative to each other at different speeds, pulling the rubber compound into the gap between the two rollers for mechanical processing.

Advantages of Rubber Open Mill
1. High - Efficiency Mixing Performance * Equipped with dual rollers rotating at different speeds (speed ratios ranging from1:1.09 to 1:1.35), it generates strong shear forces to ensure thorough mixing of rubber compounds.
* With large working diameters (160mm - 710mm) and widths (320mm - 2200mm), it can handle batch sizes from 1kg to 300kg, meeting the production needs of various scales.
2. Precise Temperature Control * Hollow rollers enable the circulation of steam or cooling water, allowing for precise
temperature regulation between 30°C - 200°C to meet different vulcanization requirements.
3. Durable Construction * Made of alloy chilled cast iron with a surface hardness of HS 68 - 75, the rollers are wear - resistant and corrosion - resistant, ensuring a long service life.
* The one - piece base and reinforced frame provide stability during high - load operations.
4. Enhanced Safety Features * Three - layer safety protection system: * Automatic overload shutdown system to prevent motor burnout.
* Breakable safety shear pins to protect the rollers from sudden excessive pressure.
* Emergency braking device with a response time of less than 0.5 seconds.
5. Wide Material Compatibility * Capable of processing over 20 types of rubber materials, including food - grade silicone, fluororubber, and EPDM, making it suitable for industries such as automotive, medical, and footwear.
6. User - Friendly Operation * Manual or electric roll gap adjustment (up to 15mm) for easy handling of different material
thicknesses.
* Ergonomic design with centralized control panels for intuitive operation.
