Summary:FIELD: processes for grinding of solid particles, including grinding of oxidizer in production of mixed solid rocket fuel for obtaining of ultradispersed fraction. ^ SUBSTANCE: method involves continuously grinding suspension in two-rotor grinder; feeding suspension to grinder by means of pump from the bottom to the top; draining ground suspension from grinder through readily detachable filter via one channel by alternatively changing-over suspension flow for feeding into emptied mixer whose bottom valve is closed, and for consuming of suspension from filled mixer, whose bottom valve is opened. Remote and simultaneous changing-over of suspension flow and bottom valves is performed upon pressure drop occurred downstream of pump. ^ EFFECT: increased efficiency and safe grinding of solid particles. ^ 1 dwg
