Industrial hammer mill for mineral processing

Optimize your material processing with an advanced hammer mill designed to efficiently grind, crush, and classify a wide range of materials from minerals to ceramics, ensuring consistent quality and enhancing your production capabilities.

Processes and Classifies Minerals and Ceramics

The Hammer Mill HM from NEUMAN & ESSER is engineered for minerals and ceramics processing, offering a robust solution for grinding, crushing, and classification. Its impact grinding principle ensures efficient size reduction, making it ideal for materials like gypsum, limestone, and clay. A continuous operation is achieved through a rotary airlock and fan system that maintains a stable material flow and discharge process. Capable of processing up to 50 tons per hour, the Hammer Mill HM delivers precise particle size limitation from 50 μm to 2,000 μm.

Designed for low maintenance, it automatically discharges challenging impurities, ensuring long service life for components. The mill’s integration into production lines is seamless, with PLC controls and adaptability for various operational conditions. Constructed with durable materials, it handles abrasives while allowing options for corrosion-resistant designs, ensuring compatibility with a range of processing environments.

Benefits

  • Enhances production efficiency with continuous operation design.
  • Prolongs component lifespan by automatically discharging abrasive impurities.
  • Adapts to diverse processing demands with versatile particle size control.
  • Minimizes maintenance needs through simple design and robust construction.
  • Integrates seamlessly into existing systems with PLC-controlled automation.
