Hammermills for grinding tough products
Optimize particle size reduction with precision-designed hammermills that efficiently tackle challenging materials like fatty and oily substrates, ensuring smooth integration into high-speed, continuous operations.

Processes Diverse Feedstocks for Particle Size Reduction
The ER Series Industrial Hammermills from CPM are engineered to tackle the toughest grinding challenges in industries such as animal feed, oilseed processing, and biomass. With a robust construction, these hammermills efficiently process fatty, oily, sticky, and difficult-to-flow products through precise particle size reduction. Utilizing a combination of cutting and impact plates, they ensure closer hammer-to-screen clearance for enhanced granulation. These hammermills support applications producing poultry feed, soybean meal, biodiesel, wood pellets, and more, with capacities adaptable to continuous, high-speed operations. The ER Series is designed for seamless integration into existing production lines, offering industrial strength construction with easily replaceable wear parts for simplified maintenance. The design includes extra fine grind screen carriage to prevent material leakage, optimizing efficiency. Available in various models to meet specific processing requirements, they cater to a range of materials from solid to granules. By bridging the gap between traditional hammermills and air-swept pulverizers, the ER Series maximizes throughput and operational flexibility, ensuring effective integration and performance across diverse industrial sectors.
