Kneader Mixer
A kneader is a device specifically designed for the mixing and processing of high-viscosity and elastomeric materials. It is widely used in industries such as chemical engineering, food, medicine, and rubber.
Definition: Through the differential rotation of two blades (usually in the form of Σ or Z) to generate shear force, it enables processes such as kneading, mixing, and vulcanization of the materials.
Working principle: The two blades rotate at different speeds (for example, 42/28 revolutions per minute), creating a combined axial compression and radial shearing motion, ensuring thorough mixing with no dead zones.
Main types and characteristics：
|
Type |
Applicable Scenarios |
Core Features |
|
ordinary type |
Basic mixed demand (such as food gel base) |
Simple structure, low cost, supports electric heating or water cooling |
|
Vacuum type |
Production of silicone rubber and sealant |
The vacuum level ranges from -0.096 to -0.1 MPa, which prevents the material from oxidizing and enhances the purity. |
|
High-temperature heating type |
Materials that require high-temperature reactions (such as hot melt adhesives) |
Supports heat transfer oil/steam heating, with precise temperature control. |
|
Multi-purpose type |
Cross-industry universal (cosmetics, battery pastes, etc.) |
Modular design, with options for hydraulic cylinder discharge, screw extrusion, and other types of discharge methods. |
Key Structures and Configurations:
Material: Components in contact with the material (cylinder body, blades) are mostly made of SUS304/316L stainless steel, which is corrosion-resistant.
Transmission System: Synchronous gear reducer + variable frequency speed control, ensuring smooth operation and low noise.
Temperature Control System: Double-layer design, supporting multiple modes such as electric heating, steam, and water cooling.
Discharge Method: Hydraulic cylinder flipping (large capacity), screw extrusion (high viscosity materials), ball valve (continuous production)
Typical application fields:
Chemical industry: Mixing of silicone rubber, sealant, and glass adhesive
Food industry: Uniform mixing of chewing gum and gelatin-based candies
Pharmaceutical industry: Efficient stirring of ointments and preparations
New energy industry: Dispersion treatment of battery pastes
Purchase Suggestions:
Capacity Selection: Laboratory use: 5L - 50L; Industrial grade: 100L - 3000L
Additional Functions: Optional with PLC control, vacuum system or waste gas treatment module according to requirements
