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.

Key Features

• Rotary Cutter Head: Features adjustable cutting angles and a quick-change blade system to simplify maintenance and improve flexibility.
• Dual Cyclone Air Cooling System: Delivers consistent, uniform cooling to maintain pellet shape and surface quality.
• Compatible with Multiple Formulations: Supports various elastomers and PVC compounds, including TPR and EVA-based materials.
• Upstream Integration Ready: Can be directly connected to kneaders or compounders with support for automatic feeding systems.
• Manual Pellet Size Adjustment: Cutting speed and pellet size can be adjusted manually to meet different product specifications.
• Flexible Output Options: Finished pellets can be packed directly or transferred through an optional screener and storage system.
• Fully Integrated Workflow: Covers feeding, extrusion, cutting, and air cooling in a streamlined four-stage process.

Applications

• Elastomer-Based Products: Such as TPR shoe materials, EVA granules, composite TPR layers, and PVC pellets.
• High-Fill & Heat-Sensitive Compounds: Formulations that are incompatible with water cooling, including high CaCO₃ content or sensitive elastomers.
• Functional Granules for Secondary Processing: Including materials for wire coating, soft elastic sheets, and other pre-compounded granule-based applications.

Technical Specifications

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.
