Dome destruction device represents support 2 accommodating channel sleeve 4 and housing solenoid coil 5 with power supply. Sleeve inner space accommodates two blocks 8, 9 to move horizontally to produce tight chamber. There are holes in said blocks while hopper housing cylindrical part has unions 12, 13 that receive hollow support bars 14, 15 to adjust clearance between blocks with the help of cap nuts 10, 11, each interacting with the union. Note here that said dome destruction device solenoid coil is protected by flexible casing and cover from above by conical top plug 16.
