ABSTRACT:
A feeding apparatus for a pneumatic conveying system comprising a guide chute and a rotary pocket feeder. The guide chute includes a plurality of parallel rod members positioned across its inlet, an upper and lower rotating tine means, and an adjustable sized outlet. The upper and lower tine means are rotated in the same direction about parallel, vertically spaced axes and have tine members that extend outwardly of their respective axis to mesh with each other. The tine members of the upper tine means also mesh with the rod members to assist in bringing material into the chute where the material is conveyed through the variable sized outlet into the pocket feeder for delivery to the conduit of a pneumatic conveying system. The empty return portion of the pocket feeder is vented into the upper portion of the chute to prevent any pressure remaining in the pocket feeder from blowing back into the chute outlet. The feeding apparatus is particularly suited to handle fibrous insulating material and other materials with a fluffy consistency.
