EXTRUSION MACHINE FOR PROCESSING OF BALLISTITE GUN POWDERS AND FUELS

摘要

FIELD: machine building. ^ SUBSTANCE: invention represents extrusion machine the actuating element of which is made in the form of two rotors arranged in open housing on parallel shafts with a gap excluding the contact in gear between opposite surfaces. Curved wedge gaps decreasing in the direction of rotor rotation are located between inner side surfaces of housing and outer cylindrical surfaces of rotors. Housing is closed along end faces with cover plates tightened with dynamically loosened pins. Gear pair providing rotor synchronous rotation is arranged between rotors and drive. ^ EFFECT: improved safety during manufacture of ballistite gun powders and fuels in homogenisation and pressing phases. ^ 3 dwg
