ENERGY AND RESOURCE SAVING TECHNOLOGY PRODUCTION OF SPHERICAL GRAPHITE
Abstract
On the basis of the experimental studies carried out at IGHTU, an energy- and resourcesaving technology for the production of spherical graphite was proposed, consisting of two sequentially installed multi-stage impact-reflection mills. In the first continuous mill with a grinding stage of 50 or more, the initial graphite is crushed and spherical particles are partially formed. In the second mill, at 3–4 cycles of transmission at significantly lower shock loading rates, the formation of “crosslinking” into spheres of finely dispersed particles of a lamellar shape occurs with the yield of spherical particles from the original graphite of 50 percent or more, which are well separated from noncrosslinked particles in the cyclone behind the mill - spheroidizer.
