Dewatering Machine, PET Bottle Recycling Machine



A highly efficient, yet low energy consuming piece of drying equipment, the dewatering machine uses centrifugal force to partially remove water from a flowing stream of material. It has the unique ability to take in material with high water content and reducing to low levels. When used in our PE film washing line or PET bottle washing line, the dewatering machine is first in a series of machines.

The dewatering machine or horizontal centrifuge is actually very similar to a friction washer; That is, at the center of both machines is a long shaft mounted with many panels or paddles. Surrounding this fast spinning shaft is a mesh screen tunnel. The entire apparatus is encased in a metal container where an electric motor is externally mounted.

As material is fed into the vertical feeder, the shaft spins at nearly 1,000 rotations per minute. The material within is continuously thrown outwards against the mesh screen tunnel. Water that pass through the mesh tunnel is collected for recycling while the plastic moves onto the next drying equipment, usually a thermal dryer. Usually speaking, a dewatering machine can lower moisture content to roughly 20-30%.


Model #: Motor Power: Main Shaft Diameter: Rotating Speed: Capacity:
HXJ400 37KW 400mm 1400 RPM 400 – 800 KG/H

The general lead time for all single-piece, standard equipment orders is 30 days. For custom orders or complete washing lines, the lead time is between 60 – 90 days. The actual lead time will depend heavily on the complexity of the project as well as the amount of machinery we have in queue at the time of your order.
