Air Cooling Pelletizer (Die-face Cutting)
Product Overview
The Air Cooling Pelletizer (Die-Face Cutting) is engineered for thermally sensitive materials such as TPR, EVA, and PVC, where traditional water cooling methods may cause deformation or surface defects. This system utilizes a rotary die-face cutting mechanism combined with a dual cyclone air cooling chamber, enabling simultaneous cutting and rapid air drying. The result is clean, uniform pellets with excellent surface quality and no water-related marks. Designed for seamless integration with kneaders or compounders, the machine supports automatic feeding and precise temperature control. It is ideal for applications involving footwear-grade materials, elastomer pellets, and specialty compounds that require non-water cooling environments.

FAQ
- Q1: What types of materials is this system suitable for?
A1: The system is designed for TPR, EVA, and PVC. It does not support TPU or high-fill compounds such as those with excessive CaCO₃ content. - Q2: Why use air cooling instead of water cooling?
A2: Air cooling prevents thermal shock, surface defects, or material degradation that may occur with water cooling, especially for heat-sensitive or specialty compounds. - Q3: Is the cutter head adjustable and easy to replace?
A3: Yes. The rotary cutter design allows for quick angle adjustments and easy blade replacement for efficient maintenance. - Q4: Does the system include a dual cyclone air cooling chamber?
A4: Yes. The dual cyclone system is standard and ensures uniform, high-efficiency cooling to maintain pellet shape and consistency. - Q5: Can the pellets be packaged directly after cooling?
A5: Yes. Pellets can be packed directly or optionally routed through a screener and storage bin depending on your workflow needs. - Q6: Does it support automatic feeding or upstream connection?
A6: Yes. The system supports automatic feeding and can be integrated with kneaders or compounders. However, automatic discharge and screening modules are optional. - Q7: Is the pellet size consistent? Does it offer automatic control?
A7: Pellet size and cut speed can be adjusted manually. Automatic sizing is not included in this model.
