The Palltruder ®

Gentle Compounding

For the production of compounds from thermoplastics and rubber with fillers of any  kind in different mixing ratios, PALLMANN has developed the Palltruder®.

Plastic powders, film, fibers and foam as wells as rubber granules or powder with inorganic or organic fillers in powder or fiber form such as limestone, talc, wood flour, cellulose powder, paper, leather, textiles, sugar cane bagasse, cotton sticks, rice hulls, etc, can be processed into free flowing homogenous granules with the Palltruder®.

The Palltrusion™-process:
More efficient and more effective than conventional granulating

The developed Palltrusion™-process is based on the gentle preparation and drying of the feed materials by means of frictional heat. Palltrusion™ is more efficient in comparison to any conventional processes for WPC granule production to date.  During the production of the raw material, unnecessary intermediate steps can be eliminated. Furthermore, Pallwood ® with a moisture content below 1 percent, is very well suited to directly produce high quality parts in further processes – therewith increasing the discharge capacity of an extruder by up to 50 percent. The system persuades through its high throughput rate at low operating costs, low space requirement and energy consumption and therewith insures, according to the Pallmann philosophy, a quick "return on investment“. By simply exchanging the die, with this unique process, desired Pallwood® recipes and therewith the optimum basic material for further processing can be produced.

The Palltruder®:
Simple in Function and Operation

The feed materials, wood, plastics and additives are continuously fed into the Palltruder® via a gravimetrical dosing system. The type of plastic- and wood flour, as well as their moisture content – maximum 8 percent – and the corresponding mixing ratio are decisive for the throughput rate to be achieved. The material mixture is equally plastified with frictional heat and pressure. Resulting steam is vacuumed off. The palltruded material is pneumatically transported into a granulator which produces a homogeneous and uniform granule. Pallwood® can be instantly processed further or, depending on the requirement, be conveyed to an intermediate bin in front of the production machine. The Palltruder® can be easily adjusted to any customer requirement in no time at all.

The Machine:
Palltruder®‚ Type PFV

With the Palltruder® Pallmann presents a world novelty to produce dry, homogeneous and free-flowing granules with high bulk density from thermoplastics and natural raw materials–Pallwood®.

The Process: 

  • Continuous feeding of the materials wood, plastics and additives by means of a gravimetrical dosing unit

  • Material mixture is equally plastified by means of frictional heat and pressure

  • Steam is vacuumed off

  • The palltruded material (Pallwood®) is pneumatically conveyed into a granulator which produces homogeneous and equal size granules

  • Pallwood® can either be further processed right away, or can be conveyed into an intermediate bin in front of the production machine, depending on the requirement.
