Abstract
The present invention relates to a material processing apparatus. The apparatus includes a frame including a pair of laterally opposed parallel sides and a base, and at least a first pair of substantially cylindrical material processing rolling assemblies, wherein each pair of rolling assemblies are driven by a hydraulic drive motor assembly, such that using the hydraulic drive motors, the rolling assemblies can be driven at a variable friction ratio.
Claims18
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.
A material processing apparatus comprising:
- a first frame supporting a first pair of substantially cylindrical material processing rolling assemblies having smooth outer surfaces positioned adjacent each other to form a compression zone between the smooth outer surfaces through which elastomeric material to be processed is selectively passed, and a plurality of corrugations formed in the surfaces of the rolling assemblies along the length of the rolling assemblies,
- drive motors associated with each of the rolling assemblies wherein the drive motors are hydraulic drive motors powered by a closed-loop hydrostatic power unit to rotationally drive each of the rolling assemblies at a different speed, with the speed differential between the rolling assemblies of at least 15:1 to provide a predetermined friction ratio at the compression zone between the smooth outer surfaces, the friction ratio providing warming of the material as it is passed through the compression zone.
A material processing apparatus comprising:
- a first frame including a pair of laterally opposed separate side members and a base member to which the side members are selectively attached, the side members supporting a first pair of substantially cylindrical material processing rolling assemblies having smooth outer surfaces positioned adjacent each other to form a compression zone between the smooth outer surfaces through which material to be processed is selectively passed, and a plurality of corrugations formed surfaces of the rolling assemblies along the length of the rolling assemblies, wherein the rolling assemblies are modular and comprise a main body portion and separable supporting end plates wherein the main body portion is selectively detachable from the end plates when the end plates are supported in bearing supports associated with the laterally opposed side members, and
- hydraulic drive motors powered by a closed-loop hydrostatic power unit associated with each of the rolling assemblies to rotationally drive each of the rolling assemblies at a different speed, with the speed differential between the rolling assemblies of more than 15:1 to provide a predetermined friction ratio at the compression zone between the smooth outer surfaces.
