  • Gripping intake system for dual belt conveyor
    Patent number: 7464808
    Abstract: A gripping intake system for a dual belt conveyor includes a hopper for storing granular material adjacent the return sections of the upper and lower loop belts of the dual belt conveyor, at least one hold down roller engaging the lower loop belt such that the upper and lower loop belts are held in spaced apart configuration prior to the conveying sections of the upper and lower loop belts being biased towards one another in face-to-face conveying relationship whereby granular material falling from the hopper comes into contact with the upper and lower loop belts which engage and accelerate the granular material via gravity and frictional contact with the belts to approximately the same speed as the belts and then feed the accelerated granular material into the dual belt conveyor.
