Centrifugal Dryer (Spin Dryer)

Grinder-Injection-Series01

The Centrifugal Dryer (Vertical Type) is an advanced high-speed centrifuge designed to efficiently remove surface moisture from both soft and rigid plastic materials during the recycling process. Engineered for continuous operation, the system uses powerful centrifugal force generated by a high-RPM rotor to rapidly separate water from plastic flakes, films, and regrind without causing material damage.

The dryer accepts material with an input moisture content of approximately 25% and consistently delivers output moisture levels of just 2–3%. It is suitable for a wide range of rigid plastics such as HDPE, PS, ABS, and PET flakes, as well as soft and flexible materials like LDPE, HDPE, and PP films.

This vertical centrifugal drying system ensures gentle yet highly effective drying of plastic flakes and virgin granules including PE, PA, PP, and PS. During operation, the high-speed rotation not only removes water but also simultaneously separates impurities, dust, paper particles, and fines, resulting in cleaner and more consistent output suitable for extrusion or pelletizing lines.

Built with a sturdy stainless-steel drum, precision-balanced rotor, replaceable screens, and low-maintenance bearings, the machine guarantees stable, vibration-free performance. Its vertical design improves drainage efficiency, reduces floor space usage, and enhances overall drying capacity. This makes it an essential component for PET bottle washing lines, film washing plants, and general plastic recycling systems that demand high-quality, low-moisture output.

Details of Centrifugal Dryer (Spin Dryer)

The centrifugal dryer (vertical type) is used in the recycling and manufacturing of plastics to effectively get rid of surface moisture on the plastics.
Its primary applications include:

  1. 1. Drying Plastic Flakes:
    Rigid Materials: Cuts down on moisture content from 25% to 2-3% for recycling or further
    Soft Materials: Well, suited for use with thin gauges of LDPE, HDPE, and PP films to remove surface water and make them suitable for use.
  2. 2. Processing virgin granules:
    used for gently drying virgin granules such as PE, PA, PP, and PS, and also separates the impurities and fines for the best quality output.
  3. 3. Moisture Reduction:
    reduces the moisture content by a very large percentage, making recycled plastics more useful in manufacturing industries.
  4. 4. Impurity Separation:
    uses centrifugal force to filter out dirt and fines from the plastics, hence providing clean and free-from-contaminant plastics.
  5. 5. Plastic Recycling:
    Indispensable in recycling processes as it involves the drying of plastics to high quality and easy processability.
  6. 6. Gentle Material Handling:
    Treats the materials gently to ensure that they are not damaged during the drying process, hence retaining the value of the recycled plastics.
    The centrifugal dryer (vertical type) plays an important role in the process of conditioning the plastic materials before they are processed for reuse or recycled, making them of high quality with low moisture and impurities. Due to its efficiency and versatility, it cannot be overemphasized as a tool that enhances the recycling of plastics and manufacturing.
