Efficient barley malt crushing with roller mills
Achieve precise particle size control in your processing line with a robust roller mill, enhancing efficiency and product uniformity for diverse agricultural and industrial applications.

Controls Particle Size and Grinds Materials
The Roskamp Series 650 Roller Mill by CPM is engineered to deliver precise particle size control for a wide range of industries, including animal feed production, oilseed processing, and ethanol manufacturing. This roller mill stands out for its single-point roll adjustment and heavy-duty relief springs, ensuring long-lasting operation and minimal maintenance. It employs V-belt drives for efficient and quiet performance, capable of processing materials into granules, powders, or solid forms with uniform consistency. Its applications span barley malt crushing, soybean meal production, and biomass processing, with throughput capacities adaptable to your facility’s needs, ranging from 5 to 25 horsepower. Designed for seamless integration, it features a large-capacity bridge-proof hopper with barnacle magnets and offers optional prehopper and agitator configurations. The mill is available with chilled cast iron rolls, and its robust construction supports continuous, high-speed operations with options for customization and technological upgrades to meet your specific processing requirements.
