METHOD TO PRODUCE COMPOSITE SOLID PROPELLANT Russian patent published in 2010 - IPC C06B21/00 C06D5/06 

Abstract RU 2407728 C1

FIELD: agriculture.

SUBSTANCE: method is realised in mixing plant, consisting of preliminary, upper and lower mixers. Initially excess of liquid-viscous components is dosed into preliminary mixer, including mixing in upper mixer. Then mixing is simultaneously started in preliminary mixer, and liquid-viscous and powdery components are synchronously dosed in amount of 20-40% of upper mixer charge volume. Afterwards dosing and mixing in preliminary mixer are stopped, and components are mixed in upper mixer for 5-10 minutes. Ratio of components mix in upper mixer is corrected by lacking amount of powdery components. Corrected mixture of components is mixed in upper mixer for 10-25 minutes, and synchronous dosing of liquid-viscous and powdery components is restored and mixed serially in preliminary, upper and lower mixers of mixing plant.

EFFECT: invention provides for elimination of ingress of non-soaked powdery components in zone of upper mixer auger operation and elimination of fuel mixture chemical composition violation.
