DETERMINATION OF THE GRANULOMETRIC COMPOSITION OF GREEKNUTS COAL BY THE SIEVE METHOD

In the article, fractional analysis of coal particles was carried out using sieve analysis. Walnuts were used as the initial raw material, when splitting the nut, dried to a constant weight at 1000C. The original shells in the amount of 1430 g were placed in heated sealed reactors. The pyrolysis reactor is made in the form of a vertical cylinder placed in a contact tubular electric furnace. The yield of charcoal at 5500C is 31.4%, which is apparently due to the high content of volatile substances in the original walnut shells. It has been established that the yield of the product composition passing through a sieve from 0.1 to 0.599 μm is approximately 2%, and the yield of the product composition passing through a sieve from 0.500 to 0.178 mm is 10-12%
