Abstract
A sweep arm assembly and cleanout port are provided for a dry bulk materials feeding system. A supply hopper having an outlet is disposed above a chamber such that material may flow from the hopper to the chamber. The chamber has a flat bottom surface. A feed trough is disposed below a slot in the bottom surface of the chamber such that material may flow from the chamber to the feed trough. A sweep arm is disposed in the chamber and located adjacent to the bottom surface. The sweep arm is rotated to 'sweep' the material in the chamber to the slot in the bottom surface. Further, a method is provided for feeding dry bulk materials. Material to be fed is loaded into a supply hopper. Material is permitted to flow from the supply hopper into a chamber, which chamber has a flat bottom surface. Material in the chamber is swept into the feed trough. The material is swept into the feed trough by a sweep arm that is rotated in the chamber adjacent to the bottom surface of the chamber. The material in the feed trough then is fed into a process at a controlled feed rate.
