This invention discloses a
metal waste recycling and
processing device and its usage method, relating to the field of
metal recycling technology. It includes a
machine base, an installation box mounted on top of the
machine base, a feeding hopper mounted on top of the installation box, a
crusher installed inside the installation box, and two rollers rotatably mounted inside the
crusher. A
torque sensor is rotatably connected to the outer right end of the rear roller, and a high-
torque motor is installed at the right end of the rear roller. An
abutment block is installed on the outer side of both the front and rear rollers. This invention features an
abutment block; when the
hardness of the
metal material is high, leading to increased roller torque and bearing friction, a pusher block drives the
abutment block to press against the roller along a slide block, cooperating with the inner rollers to provide support force compensation for the roller, reducing
relative bearing friction. When the pusher block moves upward, it simultaneously contacts the oil pusher plug, squeezing lubricating oil which is then delivered to the
oil tank via a hose, achieving simultaneous support force compensation and
lubrication protection.
