Plastic PRE Planetary Roller Extruder Durable Self-Cleaning For PVC Material

Application & Features:

Composing by the main screw to drive the planetary rollers, the optimum heat-exchaging effect created by the large contact surfaces of the planetary roller system in conjunction with short residence time of the melt helps to achieve a considerable reduction in formulation costs ,Costly stabilisers and lubricants are reduced to a minimum.

PRE planetary screw roller extruder series has on out-standing capability in mass production of many products because it uses variety of plastic resins. It fixes the screw developed by planetary screw into the center of main screw & barrel whose screw barrel, a plastication device, is made of screw in the helical gear shape and revolves to produce extrusion products.
It enables the best homogenitation and distribution effect because rolling and extrusion are performed at rather low temperature in the space between the put-together screws. Therefoce it achieves no charavteristic of a low-temperature molding extruder. 

The Planetary Roller Extruder Operating Principle:

1. Combined rolling and extruding action:
Through the intermeshing action of the toothed planetary roller system just one single revolution of the main spindle suffices to roll out the plastic melt as many as 1100 times, ensuring optimum plastification, homogenitation and dispersion. Compared with other extruder designs, this system increase the contact surface of the melt by up to five times.
 

2. Low-cost formulation:
The optimum heat-exchaging effect created by the large contact surfaces of the planetary roller system in conjunction with short residence time of the melt helps to achieve a considerable reduction in formulation costs. Costly stabilisers and lubricant are reduced to a minimum.
 

3. Self-Cleaning feature:
Since all toothed components of the machine constantly intermesh; no residual material is left in the machine when changing over from one formulation to another. 

Applications:

Mainly used in the production of sheet, card, film and other plastic products industry.
