BRIQUETTE OF IRON BASED METAL MACHINING SCRAP AND METHOD FOR PREPARATION THEREOF, AND MASHING CRUSHER FOR GRINDING SWARF AND APPARATUS FOR PREPARING BRIQUETTE USING THE SAME

摘要

A briquette meeting required strength that is formed in an energy-saving manner from ferrous metal working scrap and a method of making the briquette are provided. In a briquette formed by applying a pressing pressure to a ferrous metal working scrap, the percentage by weight of grinding chips is in the range of 10 wt % to 35 wt %. Viscous water-containing grinding chips crushed to a desired size and metal working scrap, such as gear cutting chips, are mixed in a feed hopper 7, and a pressing pressure is then applied to the raw mix by use of a compression pressing machine 8 to form a briquette of ferrous metal working scrap. The content of a grinding fluid of the viscous water-containing grinding chips is 20 wt % to 60 wt %.
