The distance between hammer and screen should be 0.5 inches (≈ 12 to 14 mm) for size reduction of cereal grains. The velocity or tip speed of the hammers is critical for proper size reduction. Tip speed is calculated by mul-tiplying the rotational speed of the drive source (shaft rpm) by the circumference of the hammer tip
It is also named hammer mill crusher, and crushes materials by the collision between the high-speed hammer and materials. It possesses qualities of simple structure, large reduction ratio, and high-efficiency. This hammer mill crusher is applicable for both dry and wet crushing. The compression strength of the materials shall not exceed 100 MPaCrushers and Their Types – IspatGuruApr 03, 2015· Hammer mills operate with close clearances between the hammers and the screen bars and materials reduce by attrition combined with shear and impact reduction. Though attrition consumes more power and exacts heavier wear on hammers and screen bars, it is practical method for crushing the less abrasive materials such as limestone and coal.Malt Handling, LLCHammer Mills. For use with distillers who want a finer crush, or are working with harder grains, such as rye, wheat, or corn, a hammer mill will be the optimal choice.
