Hammer Mill
Rotary screening machine that efficiently separates materials by size through a rotating cylindrical drum with perforated screens, ideal for composting, MSW sorting, material recovery, and size classification applications.
Overview
High-Impact Crushing
Multiple rotating hammers deliver repeated high-velocity impacts to crush and grind materials into fine particles, achieving consistent size reduction through impact and attrition forces.
Adjustable Output Size
Interchangeable screen plates with various perforation sizes allow precise control over final particle size, accommodating different processing requirements and material specifications.
Robust Construction
Heavy-duty design with hardened steel hammers and reinforced housing ensures reliable operation and long service life even with abrasive and tough materials.
Key Benefits
Fine Grinding
Produces very fine particles suitable for powder production and specialized applications.
High Throughput
Rapid rotation and multiple hammers enable high-capacity material processing.
Versatile Materials
Effectively processes biomass, wood waste, grains, minerals, and various recyclables.
Compact Design
Space-efficient vertical or horizontal configuration fits various facility layouts.
Easy Maintenance
Quick-change hammer system and accessible design simplify maintenance procedures.
Cost-Effective
Efficient grinding process reduces operating costs per ton of material processed.
Operating Principle
• Material Feed: Material enters the grinding chamber through the feed hopper
• Impact: High-speed rotating hammers strike the material repeatedly, breaking it into smaller pieces
• Grinding: Material is further reduced as it bounces between hammers and the mill housing
• Screening: Only particles small enough pass through the screen perforations
• Discharge: Ground material exits through the discharge chute for collection or further processing
Hammer System:
• Hardened steel hammers
