1.Product principle and Application
The crushing production line uses the principle of hammering. Under the drive of a high-speedand high-torque motor, the hammers on the host rotor take turns to hit the objects to be crushed in
the cavity. Through the space formed between the liner and the hammers, After the crushed object
is torn into a crushed object conforming to the specifications, a high-quality crushed material with
high purity can be obtained under the action of a magnetic device.
This production line is used to process waste car body, tinplate, household appliances,
bicycles, empty cans and other lower scraps to make it into a superior steel making raw material.
The machine continuously crushes, removes the coating film, increases the specific gravity of the
volume, prevents the electric furnace from exploding, and improves the water output rate under
certain conditions.
2.Technical conditions
1.1 (1) Ambient temperature: -20 ºC -40 ºC
(2) Production staff: 3-5 people
(3) Installation method: According to the installation diagram, the technicians guide the

3. Iron sheet for home appliances (excluding motors, compressors, shafts, etc.)
4. ≤6mm light and thin materials and similar domestic waste
25, Empty cans (wash out thin materials, coatings, etc.), non-sealed cans.
Note: After all the processed materials have been preliminarily processed, the shape and
volume need to ensure that they can smoothly enter the main machine inlet. (Such as cans, small
paint buckets, color steel tiles, car shells, etc.)
4.Not suitable for broken objects
1 Dangerous things:
a Sealed container, conduit, etc .;
b. Items that may cause an outbreak, fire, etc .;
