Discharge device for bulk materials

摘要

A roller is covered by rows of closely packed needles (8). The needle rows enclose compartments for the bulk material (4), which are limited by the needle rows in direction of transportation (A).The needle rows are parallel to each other, and extend at an angle of 20 approx. 45 deg. to the direction of discharge. They are at least 5 mm, pref. 15 mm to 20 mm high. The needles are inclined against the direction of transportation, pref. at an angle of approx. 75 deg.
