Individual magnetic blocks in the magnetic system may come off
Due to long-term operation, weak adhesion, aging adhesive, loose fixing screws, or worn-out bearings, causing the magnetic system to hit the cylinder and the magnetic blocks to fall off. This produces a cracking sound and may eventually cause a leak in the cylinder.
In this case, it is necessary to stop the machine promptly, remove the magnetic system for inspection, replace the fallen magnetic blocks, and clean up any broken magnetic blocks in the cylinder. If the problem is caused by damaged bearings, they need to be replaced.
The gap between the magnetic system and the cylinder is too small or the cylinder is not round
Normally, the clearance between the magnetic system and the cylinder should be between 2.2-3mm. If the gap is too small or the cylinder is not round enough, the magnetic sorting machine may generate frictional noise when it contacts the cylinder at high points. Sand, iron filings or other debris that enter the cylinder during assembly may also cause friction noise. Long-term friction can cause wear and tear on the cylinder, and sometimes may cause it to leak. If this problem is detected, the machine should be stopped and checked for repair. The magnetic system should be removed for cleaning, the gap should be adjusted, the roundness of the cylinder should be restored, and the worn-out parts should be replaced if needed.
The end cover is not tightly closed, causing water to enter the cylinder
If the screws that fix the end covers to the cylinder loosen or fall off or there is insufficient sealing between them, water and slurry will flow into the cylinder. The abrasion layer on the outside of the cylinder or sharp objects causing damage to the cylinder from the outside may also cause water and slurry to enter the cylinder, generating a faint friction sound. If water and slurry are detected inside the cylinder, the garbage separation machine should be stopped immediately. The magnetic system should be removed for cleaning, and all parts should be checked for damage. If no damage is found, the magnetic system should be cleaned and reassembled with a sealed gasket applied to the joint, and the screws should be tightened.
There is an obstacle in the bottom box
If such an obstacle is detected, stop the machine, remove the obstacle from the bottom box, and check the sludge removal equipment for proper functioning.
The abrasion layer on the cylinder is scratched or the cylinder is leaking
If a sharp object enters the bottom box or if accumulated debris is not removed in time and gets stuck between the slot and the cylinder, it produces a tearing and frictional sound and may scratch or damage the abrasion layer of the cylinder, or even cause a leak.
In some cases, the abrasion layer peels off prematurely due to improper materials, temperature, time, or hygiene, or the partition plate in the bottom box is accidentally welded and protrudes, causing the abrasion layer to be scratched.
If any of these phenomena are observed, the machine should be stopped and the scratched abrasion layer should be cut off and repaired. The obstacle in the bottom box should also be removed, and the cylinder should be replaced if it is leaking. Regular cleaning of the bottom box is recommended.
