Why does the eddy current metal separator smoke?

Why does the eddy current metal separator smoke? Many customers are using eddy current separators. Due to improper operation or equipment quality problems, they may encounter eddy current separators that smoke. So why does the eddy current metal separator smoke? What are the reasons for the eddy current metal separator to smoke? Magnetoelectric has sorted out the causes and treatment methods of eddy current metal separators.

The main smoking parts of the eddy current metal separator are magnetic rollers and drum skins, and one is a high-speed bearing. Among them, the smoking of magnetic roller parts and drum skin parts is more common, and the smoking of bearings generally does not occur.

Smoke coming out of the magnetic roller and barrel skin of the separator is one of the common faults of concentric and eccentric eddy current separators. It is mainly due to the friction between the magnetic roller and the barrel skin and the high speed of the magnetic roller. Therefore, the barrel skin will overheat under the influence of continuous high-frequency friction, resulting in smoke. Another situation is that due to the high field strength of the magnetic roller, when the belt is damaged and has holes, it continues to be used. Magnetic metals such as iron will heat up due to the cutting of the alternating magnetic force lines of the magnetic roller. Under the influence of long-term force, it will heat up and burn the belt and cause barrel skin damage. Once the barrel skin is damaged, the magnetic metal material will enter the internal friction magnetic roller, causing the magnetic roller and barrel skin to overheat and smoke.

Solution:

1. For prevention, it is mainly necessary to regularly check whether the belt and barrel skin are damaged. If damaged, replace them in time.

2. Clean up the inside of the equipment when workers go to and from get off work, especially the intersection of the belt and barrel skin.

3. The fine magnetic metals such as iron powder and rust adsorbed on the magnetic roller should also be cleaned up in time to prevent the iron powder and rust from heating up after long-term accumulation and accelerating the wear of the cylinder skin. Once there are holes in the cylinder skin, the iron powder and rust will enter the stainless steel protective layer inside the magnetic roller, causing the cylinder skin to conflict with the magnetic roller and thus cause smoke.
