Machinery for storage of granulated or powdered plastics and centralized feeding systems for injection molding or extrusion machines.
For all industries that need machinery for the storage of granulated or powdered plastics, Prillwitz designs and manufactures modern storage systems that include fluidizing mechanisms and discharge of the stored product.
Our silos and hoppers are used to store all types of plastics, such as polyethylene, polypropylene, polycarbonates, vinyl polychloride and polystyrene.
Main Elements We Can Supply to the Plastics Industry
Unloaders and loaders for Big Bags or maxi bags
For industries that utilize BIG-BAGS, we offer machinery for their movement, loading, and unloading. Additionally, we provide the necessary pneumatic conveying systems and handling
Pneumatic Conveying: Movement of dry materials with air
Pneumatic solid transportation systems are currently considered one of the most effective means for product transportation due to their safety, hygiene, precision, and reliability.
Industrial storage silos and hoppers
Manufacturing of industrial storage silos for raw materials: Metal silos made of steel, aluminum, or stainless steel, and flexible Trevira® fabric silos. Silos can
For mechanical transportation, Prillwitz supplies HSF screw conveyors. We also provide all the necessary equipment for bagging and packaging granules, filling large bags with PNBP and EBA bagging machines. As in other industries that handle powders and granules, air suction and filtration systems are critical in the plastics industry. In this regard, the cyclones, HDF bag filters, and low-pressure fans that Prillwitz manufactures meet the highest quality standards.
