About This Pressure Rotating Kneader Line

This pressure rotating kneader line is specifically engineered for granulating and sampling EVA, TPR, modified materials, and color master batch. It is also highly effective when used in small production runs, provided it is assorted with a specification kneader and mixing mill.

One of the most significant advantages of this line is its ability to reduce the massive energy consumption typically associated with using high-power units for granulation and modeling. By optimizing the mechanical process, it delivers exceptional results while keeping operational costs low.

Extruding materials like EVA and TPR can be challenging due to their unstable extrusion particularities. To solve this, we have successfully integrated special designs into the structure of the screw. This ensures the machine can detect and control temperature accurately and effectively, avoiding the common issues of foaming and color differences during the kneading process. The final finished granules emerge smooth, uniform, and visually appealing.

With a compact structure, stable operation, low energy consumption, and high efficiency, this granule line is the ideal solution for granule manufacturers aiming for premium quality and consistent output.

Why Choose Our Granule Line

Prevents Foaming & Color Differences

Our special screw structure design and precise temperature control system prevent the material from foaming and changing color during the kneading process, ensuring perfectly uniform granules.

Energy Saving & Cost-Effective

Reduces the large energy consumption associated with traditional high-power units. Ideal for both small-batch sampling and continuous production lines.

Smooth & Uniform Output

The optimized extrusion process ensures that the finally finished granules are exceptionally smooth and consistent in size and composition.

Compact & Stable Operation

Designed with a compact footprint and a robust frame, the line operates stably with minimal vibration, ensuring a long service life and low maintenance.

The Production Procedure

The pressure rotating kneader line operates through a highly efficient, continuous sequence to transform raw materials into finished granules:

Kneader → Extruder Mainframe → Auxiliary Cutter → Whirlwind Cooler (1st Process) → Cooling Conveyer → Whirlwind Cooler (2nd Process) → Finished Products

Applications

EVA Granulation

Perfect for processing Ethylene-Vinyl Acetate (EVA) for shoe soles, foams, and other applications requiring stable extrusion.

TPR & Modified Materials

Handles Thermoplastic Rubber (TPR) and various modified plastics that are sensitive to temperature fluctuations during kneading.

Color Master Batch

Ensures thorough mixing and uniform color distribution for color master batches, eliminating streaks and color differences.

Laboratory Sampling

Highly suitable for small production runs and sampling. It allows manufacturers to test new formulations without running large, energy-intensive machinery.

Frequently Asked Questions

How does the machine prevent foaming and color differences?
Extruding materials like EVA and TPR can be unstable. We have designed a special structure for the screw, combined with a highly sensitive temperature control system. This allows the machine to detect and adjust temperature accurately in real-time, preventing the material from overheating, which is the primary cause of foaming and color degradation.
Can this line be used for small-batch sampling?
Yes. It is specifically designed for both mass production and small-batch sampling. When assorted with a specification kneader and mixing mill, it is highly efficient for small production runs, saving the energy that would be wasted by running massive high-power units.
What is the function of the two whirlwind coolers?
After the material is cut by the auxiliary cutter, it enters the first whirlwind cooler. It is then transported along the cooling conveyer and passes through a second whirlwind cooler. This two-stage cooling process ensures the granules are cooled evenly and thoroughly, preventing them from sticking together.
What kind of maintenance does the screw require?
Because the screw is designed specifically to handle difficult materials like TPR and EVA, it is built for durability. Routine maintenance involves regular cleaning of the screw and barrel to prevent material buildup, and checking the heater bands and temperature sensors to ensure accurate readings.
