METHOD OF PELLETISING POLYDISPERSE LOOSE MATERIALS FOR MAKING BULK WEIGHT FOR FURNACES

摘要

FIELD: process engineering.SUBSTANCE: invention relates to machine building and can be used in pelletising carbon-bearing and other polydisperse loose materials for use in shaft furnaces, blast furnaces, cupolas and nonferrous metallurgy furnaces. Briquette mix prepared for compaction is fed in between press rolls and compacted by roll forming cells. Said cells are made at roll sleeves in the form of symmetric half-molds of would-be pellets. Said symmetric semi-molds differ in sizes and/or shape.EFFECT: briquettes with bulk weight of higher has tightness.1 dwg
