WAY TO PRODUCE BALLISTITE POWDER USING CONTINUOUS METHOD Russian patent published in 2012 - IPC C06B21/00 

FIELD: explosives.

SUBSTANCE: suggested invention refers to the field of explosives, notably to the way of production of ballistite powder using the continuous method. The way of production of ballistite powder with the help of the continuous method includes "cooking" of the powder mass, squeezing-out, compacting and plastification, graining and drying of the extrudate grains, recurring plastification and formation of the powder elements of the necessary standard sizes; squeezing-out, compacting and preliminary plastification as well as graining of the extrudate are performed in the upper extrusion machine of the multiple two-stage extrusion installation, and compacting and recurring plastification of the dried grains are going in the lower extrusion machine by means of compression and compacting in the plastification area.

EFFECT: ensuring safety of the technological process, combination of several process steps in one multiple two-stage installation, increase in the efficiency of squeezing.
