FIELD: chemistry.
SUBSTANCE: invention relates to the devices for the preparation of the mixed solid rocket propellant (MSRP). The mixer of the MSRP components comprises a rotating housing with bases, a loading and an unloading hatches, a vacuum line. The upper housing part comprises a piston, compacted along the inner cylindrical housing surface, with a rod passing out through the top mixer base, the cavity above which is connected to the vacuum line. The inner surface of the loading hatch cover is made flush with the cylindrical housing surface, and the top base is removable.
EFFECT: reducing the costs of the manufacturing process of mixed solid rocket propellant due to reducing the propellant mass residue remaining in the mixer after the final drain.
