Abstract:
1. A material processing apparatus comprising: a first frame including a pair of laterally opposed sides and a base; and at least a first pair of substantially cylindrical material processing rolling assemblies having a substantially smooth outer cylindrical surface, with the rolling assembles mounted in the laterally opposed sides relative to one another to form a compression zone between the smooth outer surfaces of the rolling assemblies, wherein each of the rolling assemblies are driven by a drive motor assembly being hydraulic drive motors powered by a closed-loop hydrostatic power unit, such that using the drive motors, the respective rolling assemblies can each be driven at a predetermined speed to provide a predetermined friction ratio between the smooth outer surfaces of the rolling assemblies, wherein the predetermined friction ratio is provided by rotating the smooth outer surfaces of the rolling assemblies at a differential speed of at least fifteen to one relative to one another such that material passing through the compression zone between the rolling assemblies is subjected to compression and shearing forces from the substantially smooth outer surfaces of the rolling assemblies due to the friction ratio.
