Second. From the material requirements of metal shredder machine, pay attention to the following points:
1. Material requirements: The main shaft should be forged with alloy structural steel (40CrMo), the combined bending and torsional stress should be less than 55N / m㎡ and quenched and tempered, and the hardness should not be lower than HB217-255;

2. Structural assembly requirements: The edges of the joint surface of the parts should be neat and symmetrical, and there should be no obvious misalignment; the circular arc surface of the liner and the shell should be smooth and regular, and the draft of the liner is not allowed; the mechanism design Requires replacement of the hammer head and the liner without the need to remove the rotor and is convenient. The weight of each hammer head must not be too large, and the peripheral speed of the end of the hammer head must be less than 40m / s, otherwise the hammer head will wear too quickly. At the same time, for operational balance, the error between the hammer heads must not be greater than 0.5kg. And the large crusher should be equipped with: hydraulic opening and closing of part of the shell; hydraulic belt tensioning device of the V-belt; hammer head pivot extraction device; the rotor support should use the self-aligning spherical roller bearing.
3. Welding requirements: The welding of the shell of the shredder machine meets the general standards.
4. Inspection requirements: Flaw detection should be performed after finishing, and defects such as slag inclusions and cracks are not allowed; inspection of trachoma, cracks, and blowhole casting defects of the hammer head; inspection of weld seams; balance test after rotor assembly.
5. Shredder machine conducts no-load test run to test the vibration speed and bearing temperature of the rotor and driving parts.
6. The used bearings, motors, and service life should be longer than 100,000 hours.
In addition, in the procurement of shredder machine equipment, do not only consider the price factor. Considering the price, sometimes you will encounter some metal shredder machine manufacturers with low credibility. In addition to purchasing equipment, you must have some knowledge of the production process, it is best to visit the field, you can also find some related videos on the Internet, learn more, or call a person who knows professionals to consult. The key point is that when inspecting the goods, you must check whether the dimensions and specifications of the equipment and the signed contract agreement are consistent. After installation and commissioning, you must ask the manufacturer's technicians to ignite the trial production on the spot and closely observe the equipment for leaks. .
