ROLL-TYPE BRIQUETTING PRESS Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: this relates to presses intended for producing briquettes from loose and plastic materials for metallurgical, coal, mining, and other industries. Press has hollow rolls installed in body and provided with rotation drive unit, and extracting device in the form of rods with means for their displacement. Rods in quantity equal to quantity of seats in roll are fasten in roll body radially and spring-loaded with possibility for advance movement. One end of each rod is provided with striker having supporting surface partly forming bottom of seat. Means for movement is in the form of supporting axles installed coaxially to rolls and in their hollows. They are provided with protrusions which can interact with ends of rods which are opposite to ends provided with strikers. Supporting axles can be turned and fixed, and they have recesses which can receive ends of rods which are opposite to ends having supporting surface. This design prevents sticking of briquettes after their formation and repeated getting into zone of deformation and compaction. EFFECT: high efficiency. 5 dwg
