METHOD AND APPARATUS FOR CALIBRATING BULK MATERIALS

摘要

FIELD: agricultural engineering, may be used in mining and construction material industries. SUBSTANCE: method involves supplying basic material onto screens and sieving it by oscillating during passage of material over screen generatrix; separating fractions of different size. Quality of calibration is enhanced by passage of material through screen with minimum section and by continuous motion and rotation. EFFECT: increased efficiency of method by intensified mixing of material and wider operational capabilities. 4 cl, 3 dwg
