DEVICE USED FOR INTERMIXING OF THE COMPONENTS OF THE EXPLOSIVE COMPOSITIONS AND PRESSING THE PRODUCTS OUT OF THEM Russian patent published in 2007 - IPC C06B21/00 

FIELD: chemical industry; rocketry; other industries; devices for intermixing of the components of the explosive compositions and pressing the products out of them.

SUBSTANCE: the invention is pertaining to the field of intermixing of the explosive compositions, including the powders and the solid rocket propellants. The device includes the upper and lower mixers with the stirrers and the feed screw transportation and pressure-tight devices with the drives. The feed screws of the mixers in the loading part are executed cylindrical single-thread, and in the pressing part - the conical double-threaded. At that on the turns of the feeding screw pressing part there is the annular groove in width of 0.5 ... 0.7 of the pitch of the turn perpendicularly to the axis the feed screw at the distance of 0.6... 0.9 of the pitch of the turns from the feed screw inlet in the body of the mixer. The invention is intended to ensure the safe and optimal mode of operation of the device for intermixing of the components of the explosive compositions and pressing the products out of them.

EFFECT: the invention ensures the safe and optimal mode of operation of the device used for intermixing of the components of the explosive compositions and pressing the products out of them.
