Scraper-type chip conveyor is mainly used for separating and removing non lumping fine chips not exceeding 50mm in length during dry or wet processing, applicable to chips of various materials. Magnetic scraper-type chip conveyor finds its main application in conveying of short steel scraps and cast iron scraps during wet processing. Driven by motor reducer, scraper chip conveyor adopts chains to bring along the scraper, to scrape the chips on the floor-plate of conveyor out into the chip collecting cart. This device is reliable, with stable performance, quantitative chip conveying, convenient dismantling and easy maintenance. Magnetic-type scraper chip device is added with permanent magnet chip device is added with permanent magnet magnetic field in floor-plate of a chip conveyor based on the scraper-type chip conveyor, when chips are first adsorbed onto the floor-plate before being scraped out by the scraper.
