Characteristics
HIGH GAUSS MAGNETIC SEPARATOR.
This machine is developed for removal of iron particles from the used coolant forcold-rolling process and Alkali cleaning solution for alkali cleaning line.

Features of HIGAMS
1. High removal ratio and able to remove of fine iron particles.
2. Able to reduce the rolling oil usage because of the efficient system.
3. Fully automated and maintenance easy.

There are two cases that coolant contact

The effect to sucking force is so much byCorrosion and wearing out

Forced discharging by ScraperIron content to be discharged by water,steam (vapor and compress air etc)

Less effect to sucking force by

Iron is discharged by vibrating Magneticpole(iron /steel ball)About 10% in the coolant for Ordinary steel About 20% in the coolant for Ordinary steel About 40% in the coolant for Ordinary steel
