Efficient fine size reduction for recycling applications
ZENO hammer mills are engineered for efficient secondary size reduction in industrial recycling and material processing plants. Designed and manufactured in Germany, these machines provide high performance, reliable operation, and long service life in demanding environments.
ZENO hammer mills are designed to process a broad range of materials including wood, plastics, paper and cardboard, textiles, light composites, and mixed industrial waste streams. The impact-based crushing principle enables efficient size reduction and consistent particle output for further processing.
With flexible configurations and heavy-duty design, ZENO hammer mills can be integrated into complete recycling and material processing lines or operated as stand-alone units. The machines are engineered for continuous operation and maintenance-friendly servicing, ensuring stable long-term performance.


Technical insights on ZENO Hammer mills
Impact-based size reduction
ZENO hammer mills use high-speed rotating hammers to achieve effective secondary size reduction. The impact-based crushing process allows efficient processing of pre-shredded materials and produces a homogeneous output suitable for further processing.
Patented quadro tool system
ZENO hammer mills feature a patented multi-use hammer system that allows the tools to be reused in multiple positions. This design significantly reduces tool costs and extends service life compared to conventional hammer mill designs.
Bidirectional operation and balanced wear
The symmetrical machine design allows operation in both directions of rotation, ensuring even wear on the crushing hammers. This increases tool lifetime and improves operational efficiency over long production periods.
Adjustable stator knives and screen protection
Material is crushed against externally adjustable stator knives before passing through the screen. This design protects the screens from excessive wear and allows adjustment to maintain optimal crushing conditions..


Screen system for controlled particle size
Large screen surfaces allow efficient discharge of processed material and help maintain high capacity with reduced energy consumption. Interchangeable screens make it possible to control the final particle size according to process requirements.
Maintenance-friendly industrial design
ZENO hammer mills are designed for industrial serviceability with hydraulic screen drawers and hydraulic hood opening systems. These features allow fast access for inspection and maintenance, minimizing downtime and improving plant availability.
