Type KS / FS KS / FS Applicable to the secondary filtration of cutting sludge Type KS・Type FS (magnetic drum diameter: φ140 mm for models 4 to 18 and φ216 mm for models 24 to 36) Secondary Filtration for Cutting/Shaving Process Type Features Effective design based on the analysis of magnet arrangement and shape which improved the attracting power of the magnet. Amount of chips stuck on the squeeze roller is reduced and the performance improved. Blade life will extend and the product defect ratio will decrease. Practical Usage of FINE MAG Secondary filtration of veryfine muddy sludge for cutting cast iron. Filtration of shaving process coolant liquid. Filtration of magnetic sludge which is contained in the coolant from the centrifugal oil separator.
