| High gradient magnetic separation(HGMS) was applied to the treatment of fluids used in the cutting and grinding of (a) aluminium based alloys and (b)iron based alloys. This method has a number of advantages, as follows: (1) The fluid can be cleaned down to sub-micron sizes without the addition of filter aids. (2) This process leaves a residue of metal particles without contamination and which is sufficiently clean to be sold for scrap. The fluid was treated in each case in a single pass at a flow velocity of 5 cm/s with an applied magnetic field of 5 Tesla, and the input and output fluids from the filtration trials were analysed. The mass per unit volume of solid particles was determined in three separate particle ranges: > 11 mm, 11 mm to 3 mm, and 3 mm to 0.45 mm. All the particles were removed except in the smallest size where a small fraction remained. |
