These dual shaft Industrial Shredders use low speed, high torque hook shear blades manufactured of high alloy heat treated steel mounted on hexagonal shafts. The number of hooks, reach of hooks, and blade thickness are determined by the material being reduced.
Available with cutting chambers ranging in size from 17" x 14" to
60" x 40" with motors from 10 HP to 450 HP.
(see chart below for full machine specs and sizes)
Counter rotating shafts turn at slightly different speeds increasing the efficiency of the cutting action.
Any overloads caused by foreign material are sensed by the PLC controller and cause the shaft rotation to stop and reverse direction to clear the foreign matter, and then resume. Shock loads caused by normal shredding operation are absorbed by a patented shock absorber drive train.
Shredders can be configured for each unique shredding application by choosing different knife widths, knife hook design, fingers, and screens to achieve the exact shred size and production rate needed. This photo shows the shredding chamber with the infeed hopper removed to show how the hooks on the knife run in opposite directions to shred the incoming material.
Hardened gears are used on each shaft to convey the high torque and low speed into the knives in the shredder chamber.
