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.
