LOADING SYSTEM FOR PARTICULATE MATERIALS

摘要

A loading system for light particulate materials. A storage hopper (l2) for granular material includes an airlock (26) by which the material is fed into an air stream. The air and accompanying material are fed to a distribution pipe (24) with multiple flexible downward projecting fill spouts (40) which are spaced at regular intervals, Each spout (40) has an associated control valve and air pressure sensor (56) within the spout (40), so that as a container being loaded by the spout is filled, and the pressure in the spout increases beyond a preselected level, the spout is closed off and material automatically is transported to the next open spout. Air operated spreader heads (60) may also be furnished at the lower ends of the spouts (40) to assure that the container volumes are complete filled..
