Assignee:

Certainteed Corporation - Valley Forge PA

International Classification:

B02C 19/22

US Classification:

241 60, 2412601

Abstract:

A system for processing material has a power supply and a machine having a hopper for receiving and passing material to an auger. The auger has a shaft with an axis about which it rotates, a helical flighting mounted to the shaft, pins mounted to the helical flighting, and paddles mounted to the shaft. The radial outer edge of the helical flighting is crenelated with periodic notches that form rectangular blades on the helical flighting. The pins are rotationally and angularly aligned with leading edges of the rectangular blades. The system may include a vehicle, such as a trailer, having first and second compartments separated by a partition. The power supply is located in the first compartment and has a power supply member extending though the partition. The machine is located in the second compartment and coupled to the power supply member.
