Product catalog summary
Pulverizer Overview
Herbold's PU Series pulverizers are high-speed grinders designed for fine grinding applications. They feature a compact design, short material dwell time, and easy adaptability to various materials, including ground stock from pipes, films, PE-virgin material, vulcanized rubber, and products from the food and chemical industries.
Specifications and Performance
The PU Series includes models like PU 300, PU 500, and PU 500 Twin, with throughputs ranging from 150 kg/h to 1600 kg/h depending on the material and model. The performance is influenced by material quality, infeed size, and grinding tool condition.
Functional Diagram and Operation
Material is fed into the grinder via a dosing unit, with overload control. Toothed discs pulverize the material, which is then evacuated by suction. The system can include a screening machine for oversized material.
Advantages
Key benefits include short material dwell time, easy tool changes, compact construction, and external grinding gap adjustment. The PU 500 Twin system offers high throughput and quality, particularly for LLDPE powder production.
Grinding Tools
Herbold pulverizers can be equipped with various grinding tools, such as wing beaters, turborotors, and pinned discs, to suit different materials and fineness requirements.
Product Range
Herbold offers a range of size reduction technologies, including granulators, shredders, hammer mills, and more. The PU Series is available in sizes from PU 180 to PU 1250, with varying capacities and power requirements.
Contact Information
Herbold Meckesheim GmbH is based in Germany, with a US subsidiary in Rhode Island. Contact details for both locations are provided for further inquiries.
