J v engineering & conveyors provides paper band-cum-magnetic coolant clarifiers. Magnetic filters used in filtration of coolants and lubricants. Both ferrous and nonferrous particles can be filtered where high degree of purification is required and contaminants differ in form, size and composition. Paper band filtering is recommended for grinding, honing, transfer lines and machining centres. These can also be used for rolling mills for filtering coolant, which helps to improve the surface finish of the sheets.
