Abstract
Coolant fluid cleaning method, system, and apparatus use a rotating magnet to remove particulate matter from a fluid used to cool or lubricate a machining or other operation. Such system includes a rotating magnet in fluid communication with apparatus circulating fluid past the rotating magnet. A scraper blade removes particulate matter which is picked up by the rotating magnet. The system or apparatus can include a dirty fluid reservoir, one or more conveyor which removes chips and particulate matter from the dirty fluid reservoir, and a clean fluid reservoir. The rotating magnet collects particulate matter in the dirty fluid reservoir and discharges the collected particulate matter to a discharge conveyance. When the rotating magnet is used in combination with a disc filter, the magnet relieves some cleaning load from the disc filter.
