Systems for shredding fibrous material are described. In some embodiments, the system includes a cart that includes a hopper that includes an auger motor for shredding fibrous material and a blower motor configured to blow the shredded fibrous material onto structures for fireproofing. The cart may include a handle, one or more wheels, and/or forklift apertures to aid in transport.

A viscous food product dispensing system having a transport section for receiving a particulate food product from a bin, an auger for processing and conveying the received particulate food product from the transport section into an outlet adapter via one or more flutes, a milling device housed in the outlet adapter, and a discharge nozzle in the outlet adapter that pinches off the viscous food product created by the milling device. The auger has a unique design that allows it to engage and break whole nuts.

A screw shaft for a vertically stirred grinding mill is arranged so as to be accommodated within a grinding chamber of the grinding mill while extending in a longitudinal direction. The screw shaft comprises a central shaft and at least one screw flight surrounding the central shaft, and the central shaft comprises an outer shaft wall defining a cavity within the interior of the central shaft, which cavity is closed at least at one longitudinal end of the central shaft.

A roof removal machine may include an auger assembly at least a first helical auger flight coupled to a central axle, and a plurality of blades coupled to an outer edge of the auger flight. A motor is operably coupled to the auger assembly and configured to rotate the auger assembly about the axle in at least a first direction of rotation. The blade edge of each of the blades is oriented transverse to the first direction of rotation. In some examples, a second helical auger flight is also coupled to the central axle, and the two auger flights may be oppositely-handed with respect to each other, such that roof debris is moved toward a central extraction port.
