METHOD OF EXPLOSIVE COMPOSITION COMPONENTS MIXING Russian patent published in 2016 - IPC C06B21/00 C06B45/00 C06D5/06 

FIELD: blasting operations.

SUBSTANCE: invention relates to explosive compounds components mixing, including mixed rocket solid fuels (MRSF). After components preparation, performing dosing of liquid-viscous and powdery components, including explosive and oxidant, and their mixing. Powdered hardener, lead oxide is preliminary mixed with plasticizer at ratio of 0.25:0.05-0.25:0.08, and surface active substance (SAS), lecithin, is dissolved in plasticizer at ratio of 1:10-1:15. Remaining plasticizer is introduced into mixer in parts: one part is after SAS solution loading, and second one is after hardener with plasticizer mixture loading. Hardener with plasticizer mixture is introduced into mixer after last portion of oxidizer dosing and mixing. Explosive and oxidizing agent are introduced via individual leak-tight loading lines by creating carbon dioxide environment in mixer prior to loading explosive, and vacuum at residual pressure from 20 to 50 mm Hg prior to metal fuel powder and each oxidizer portion loading.

EFFECT: method provides uniform distribution of powder components in fuel weight, including powder hardener, and high manufacture ability while maintaining required viability.
