Oil Heated 6-Inch Laboratory Plastic Open Type Two Roll Mill

The Oil Heated 6 Inch Laboratory Plastic Open Type Two Roll Mill is an advanced laboratory-scale mixing and kneading equipment widely used in the rubber, plastic, and polymer industries. It is designed to efficiently blend and process materials such as rubber compounds, plastics, and chemicals by providing precise control over the material temperature and mixing process. The oil heating system enables accurate temperature control, which is essential for achieving optimal material processing conditions.

Product Overview

The 6-inch Oil Heated Two Roll Mill features two large parallel rollers,  with a diameter of 6 inches (approximately 150 mm). These rollers rotate in opposite directions and are heated via an oil circulation system, allowing for stable and uniform temperature control. The mill is widely used for material preparation, rubber compounding, blending plastics, and mixing chemical compounds in research, development, and small-scale production environments.

• Roller Diameter: 6 inches (150 mm)

• Heating System: Oil heating system for precise temperature control

• Machine Type: Open-type, allowing full visibility during operation

• Use Case: Ideal for laboratories, small-scale production, and research applications in the rubber, plastic, and polymer industries.

Key Features

6-Inch Roller Diameter

• Larger Capacity: With a 6-inch diameter, the rollers can process larger amounts of material compared to smaller mills, making it suitable for higher-volume laboratory tests or small batch production.

• High Precision: The larger roller size allows for finer control over material processing, providing better mixing and kneading performance.

Oil Heating System

• Precise Temperature Control: The oil heating system ensures uniform and stable heating of the rollers, which is essential for maintaining consistent material properties during processing. It prevents overheating and ensures that the material does not degrade due to high temperatures.

• Efficient Heating: Oil heating offers better thermal conductivity than water-based systems, ensuring quicker and more consistent heating across the rollers.

• Adjustable Temperature Settings: The temperature of the rollers can be easily adjusted and controlled to suit the specific requirements of different materials and formulations.

Open-Type Design

• Improved Visibility: The open-type design allows operators to observe the material processing in real-time. This design is particularly beneficial in laboratory settings where adjustments may need to be made based on the material’s behavior.

• Easy Loading and Unloading: The open structure also facilitates quick and easy loading and unloading of materials, increasing the overall efficiency of the mixing process.

High-Quality Roller Material

• Durability and Resistance: The rollers are typically made from high-strength alloy steel, often chrome-plated or nitrided to enhance wear resistance and prolong the life of the equipment.

• Superior Performance: The high-quality surface treatment of the rollers ensures minimal material adhesion and easy cleaning after each use, preventing contamination and material degradation.

Versatile Applications

• Multiple Materials: The 6-inch mill is suitable for processing various materials such as rubber compounds, plastics, thermoplastic elastomers (TPE), thermoplastic polyurethanes (TPU), and chemical additives.

• Ideal for Laboratory Research: It is commonly used in research laboratories to prepare material samples, create test batches, and develop new material formulations.

Working Principle

1. Material Feeding: Materials (such as rubber, plastic, or polymer granules) are introduced into the gap between the two rollers.

2. Roller Rotation: The two rollers rotate in opposite directions, generating shearing and compressive forces that knead and mix the material.

3. Oil Heating System: The oil circulation system heats the rollers to a precise temperature, maintaining the ideal conditions for material processing. The oil temperature can be controlled to ensure the material reaches the optimal viscosity for mixing.

4. Material Processing: As the material moves through the gap between the rollers, it is thoroughly mixed, refined, and kneaded to achieve the desired consistency and properties.

5. Discharge: After sufficient mixing, the material is discharged from the rollers, either manually or using an automatic discharge system. The material may be processed further depending on the specific requirements.

Applications

Rubber Industry

1. Rubber Compounding: The mill is ideal for mixing rubber compounds, integrating additives such as carbon black, plasticizers, and curing agents into raw rubber.

2. Testing New Formulations: Laboratories use this mill to prepare experimental rubber blends, test new formulations, and create small batches for further testing.

Plastics and Polymers

1. Polymer Blending: It is used to blend different thermoplastics, elastomers, or additives to create customized formulations for specific applications.

2. Thermoplastic Elastomers (TPE) Processing: This mill is highly effective for kneading and mixing TPE, TPU, and other thermoplastic materials.

Chemical Industry

1. Chemical Additive Mixing: It can blend a wide variety of chemicals and polymers, mixing additives, resins, and fillers into base materials to enhance their properties.

2. Colorant and Filler Integration: The mill is commonly used to incorporate colorants or reinforcing fillers into polymer or rubber materials.

Laboratory and Research

1. Material Testing: Ideal for testing small-scale formulations in research environments, enabling the development of new products and materials.

2. Prototype Production: Used for prototyping new materials in small batches before larger-scale production.
