The 7-inch Small Rubber Two Roll Open Mill is a compact and efficient piece of equipment designed for the mixing, blending, and refining of rubber compounds, thermoplastics, and other materials in laboratory or small-scale production environments. It is widely used in research, development, and testing applications within the rubber, plastic, and chemical industries.
The 7-inch Small Rubber Two Roll Open Mill features two horizontally aligned rollers that rotate in opposite directions to create shear and compressive forces, effectively mixing and kneading materials. The mill can be equipped with various heating options, such as electric heating, oil heating, or water cooling systems, depending on the material requirements. It is commonly used for preparing rubber compounds, blending thermoplastics, and mixing other materials to achieve the desired properties.
Roller Diameter: 7 inches (approximately 175 mm)
Heating System: Can be equipped with electric heating, oil heating, or water cooling systems
Use Case: Primarily used for rubber compounding, thermoplastic mixing, and material testing in laboratories or small-scale production settings
Increased Mixing Capacity: The 7-inch rollers allow for handling larger quantities of material compared to smaller mills, making it suitable for higher-volume laboratory tests and small batch production.
Improved Mixing Performance: The larger roller size facilitates better material distribution and ensures uniform mixing, leading to high-quality finished products.
Customizable Heating Options: The mill can be equipped with an electric heating system, an oil heating system, or a water cooling system based on the temperature control requirements of different materials.
Precise Temperature Control: Ensures accurate temperature management to prevent overheating or degradation of materials, especially when working with heat-sensitive compounds.
Wide Range of Gap Adjustments: The gap between the rollers can be adjusted from 0.1 mm to 6 mm, allowing for customization based on material characteristics and processing requirements.
Optimal Material Processing: Fine-tuning the roller gap ensures effective mixing and refining of various materials.
Durability and Resistance: The rollers are made from high-strength alloy steel, with additional surface treatments such as chrome plating or nitriding to enhance wear resistance and extend the operational life of the mill.
Non-Stick Surface: The chrome-plated or nitrided surface prevents material adhesion, ensuring easier cleanup and preventing cross-contamination between batches.
Emergency Stop System: Equipped with multiple emergency stop buttons, providing a safe and user-friendly operation environment.
Humanized Design: The machine includes reverse functions and other ergonomic features that minimize the risk of operator injuries.
