a pair of screens, each of said pair of screens disposed, between said opposing side walls in said bottom wall of said hammer mill housing, in an alignment with a respective one of said pair of rotors,
baffles spanning said distance between said opposing side walls and disposed in a spaced apart relationship with each other on an interior surfaces of said top and bottom of each of said pair of chambers, and
a hammer mill chute extending from said top wall and having one end thereof in an open communication with one of said pair of chambers;
a shredder assembly comprising:
a mounting member,
a pair of cross-cut shredders mounted in a vertical tandem arrangement with one another, each of said pair of shredders comprising:
a shredder housing,
a pair of shredder rotors mounted in tandem with one another and for a rotation within said shredder housing,
cutters mounted on each of said pair of shredder rotors for said rotation therewith, said cutters overlapping one another during said rotation,
a passageway defined between shredder housings in an open communication therewith,
a bottom shredder housing being configured and mounted in an open communication with said hammer mill chute, and
a shredder chute disposed on an upper shredder housing in an open communication thereof;
a power drive assembly, comprising:
a pair of gearbox assemblies, each coupled to one of said pair of cross-cut shredders,
a first pair of electric motors, each of said first pair of electric motors coupled to a respective one of said pair of gearbox assemblies, and
a second pair of electric motors, each of said second pair of electric motors coupled to a respective one of said pair of rotors within said hammer mill assembly;
and
a control assembly, comprising:
a transformer,
an ON/OFF switch,
a AC-DC converter coupled to said transformer,
a control unit comprising programmable logic device(s),
motor contactors, each having a coil thereof coupled to said control unit and having contacts thereof mounted in a circuit between source of electric energy and a respective electric motor,
a pair of relays, each of said pair of relays having a connection with said control unit and a connection with said respective motor of said first pair of motors,
a first pair of motor current measuring members, each of said first pair of motor current monitoring members coupled to a respective one of said pair of relays and configured to measure current consumption at one from said first pair of electric motors,
a second pair of motor current measuring members, each of said second pair of motor current monitoring members coupled to said control unit and configured to measure current consumption at one from said second pair of electric motors,
a user interface comprising at least a touch screen,
fuses coupled to protect said transformer and each motor from an overcurrent condition, and
a safety circuit comprising a safety switch coupled to a source of DC voltage from said AC-DC converter, an emergency switch mounted in series with said safety switch, and a safety relay having a coil thereof mounted in series with said emergency switch and having a first normally open contact thereof mounted an operable to display actuation of said safety circuit on said touch screen and a second normally open contact mounted and operable, during said actuation of said safety circuit, to disconnect power from control units outputs.
