Industrial roller compaction for chemical applications

Enhance material flow and density with advanced roller compaction technology, ideal for transforming bulk powders into uniform granules, ensuring efficient processing and reduced waste in your production line.

Compacts and Granulates Bulk Materials Efficiently

The PP Series from Alexanderwerk is engineered for optimized compaction and granulation of diverse bulk materials, tailored for chemical, pharmaceutical, and industrial applications. By utilizing a vertical roller orientation and vacuum de-aeration, this equipment effectively manages material densification and particle size distribution. It’s suitable for applications ranging from pigment powders and 3D printed components to battery electrodes and protein supplements. With processing capacities reaching up to 25,000 kg/h, depending on the model, the PP Series facilitates high throughput in continuous operations. Its robust construction features double-sided bearing rollers, allowing for high press forces up to 96 kN/cm, making it efficient for dense material compaction. The integrated control system ensures seamless automation, enhancing operational consistency and efficiency. Available in stainless steel, the PP Series is constructed for durability and material compatibility, vital for handling corrosive substances typical in fine chemicals production. Designed with hygiene in mind, this equipment supports easy maintenance with components accessible for cleaning and CIP options. Customizable features, supported by Alexanderwerk’s engineering expertise, allow for precise tailoring to meet specific processing needs.
