FIELD: loading and unloading methods and equipment for hard-grained and easy-caking powder materials. SUBSTANCE: method involves arranging flexible drawing means made as ropes with washers put thereon into device; guiding ropes in hopper height direction; connecting rope lower ends to door closing hopper outlet orifice such that ropes may be disconnected one-by-one or in group from door; moving ropes by outlet orifice opening for material bridges destruction into hopper. EFFECT: decreased power consumption; easing hard-grained material unloading; simplifying structure; extended field of application. 9 cl, 5 dwg |
