Primary hammer mills often require manganese steel hammers due to severe impact resistance requirements. Manganese steel hammers are also the choice for customers who rebuild their hammers with manganese weld and or carbide overlays. Columbia Steel can also supply manganese hammers with factory applied chrome carbide overlay.Hammers are designed to be flipped after one side wears out for maximum lifespan. Screens can be quickly changed to accommodate different moisture levels and desired particle size. Hammer Mills come in variety of sizes for different industries. Our machines are primarily designed to cater to grinding grains such as corn, wheat, and barley.
