Vacuum Type Double Rotor Silicone Kneading Machine, Silicone Dough Mixer

A Double Rotor Silicone Kneading Machine is a specialized piece of equipment used in the rubber and silicone manufacturing industries. It is designed to mix, knead, and homogenize silicone compounds, rubber, and other similar materials. The machine features two rotors that rotate in opposite directions, creating a shearing and kneading action that ensures thorough mixing and uniform consistency of the material.

Key Features:

1. Double Rotor Design:

   • The machine has two rotors that rotate at different speeds, often in opposite directions. This creates a strong shearing force, which is essential for breaking down and mixing materials effectively.

2. High Mixing Efficiency:

   • The dual rotors ensure that the material is evenly mixed, reducing the risk of unmixed or poorly mixed batches.

3. Temperature Control:

   • Many models come with temperature control systems to maintain the optimal temperature for the material being processed. This is crucial for silicone and rubber, as their properties can change with temperature.

4. Robust Construction:

   • The machine is typically built with heavy-duty materials to withstand the high stresses and strains of kneading tough materials like silicone and rubber.

5. Variable Speed Control:

   • Operators can adjust the speed of the rotors to suit different materials and mixing requirements.

6. Safety Features:

   • Includes safety mechanisms such as emergency stop buttons, safety guards, and overload protection to ensure safe operation.

Applications:

• Silicone Rubber Production: Used to mix silicone rubber with additives, fillers, and curing agents.

• Rubber Compounding: For mixing rubber with various chemicals and fillers to create rubber compounds.

• Plastic and Polymer Mixing: Can also be used for mixing plastics and polymers, especially those requiring high shear forces.

• Adhesives and Sealants: Useful in the production of adhesives and sealants where thorough mixing is required.

Advantages:

• Uniform Mixing: Ensures a homogeneous mixture, which is critical for the quality of the final product.

• Time Efficiency: Reduces the time required for mixing compared to manual or single-rotor machines.

• Versatility: Can handle a wide range of materials and viscosities.

• Consistency: Provides consistent results batch after batch, which is essential for industrial production.

Considerations:

• Maintenance: Regular maintenance is required to keep the machine in optimal condition, especially given the high stresses involved.

• Cost: These machines can be a significant investment, so they are typically used in industrial settings where high-volume production is necessary.

• Space Requirements: The machine can be large and requires adequate space for installation and operation.

Conclusion:

The Double Rotor Silicone Kneading Machine is an essential tool in the rubber and silicone industries, offering high efficiency, consistency, and versatility in mixing and kneading operations. Its robust design and advanced features make it suitable for a wide range of applications, ensuring high-quality production of silicone and rubber products.

Technical Parameters:

Structural principle of silicone kneading machine

The inside of the copper body and the stirring paddle should be made of stainless steel and polished. The purpose of using stainless steel is to prevent materials such as silicone from chemically reacting with carbon steel and contaminating the materials. Polishing is to make the surface of the copper body and the stirring paddle smooth to prevent materials from sticking to them and facilitate cleaning.

1. The parts of the silicone kneading machine that contact the material are made of 304 stainless steel, and other parts can be made of carbon steel, which can save a certain amount of production cost.

2. Discharging method of silicone kneading machine: Most silicone kneading machines use hydraulic steel turning to discharging. The viscosity of the stirred silicone is relatively large. When the cylinder is turned over, the material is poured out like a dough, which is faster than the screw discharge speed.

3. The silicone kneading machine generally adopts a normal temperature and pressure elastic configuration. The silicone does not need to be heated or vacuumed when stirring, so there is no need for a vacuum pump, buffer tank, and shaft head with ordinary packing seal.
