Seed grader CR series

drum

Separates grains into smaller fractions. The capacity is obtained using the drum diameter and number of screens. Calibration precision is obtained using the rotation speed and drum inclination. Operating principle The product is fed by way of gravity into a cylindrical rotary drum covered with interchangeable perforated screens. It then passes through various screening sectors with predetermined hole sizes. The drum is then tilted in accordance with the roll-off angle of the product, which then falls into separate dedicated hoppers. The choice of screen depends on the size of the product being calibrated.
