FIELD: devices for contacting of solid materials in the form of loose particles with liquids or with liquids and gases in reactor. SUBSTANCE: device includes body accommodating screening member where zone contacting is effected. Screening member is made in the form of revolving screen 5. During operation, revolving screen 5 rotates in bath 10 containing gaseous or liquid medium contacting with solid material. Bath 10 is installed for lowering to provide for separation of solid material particles found in revolving screen 5 from medium found in bath for regulation of final stage of chemical reaction or physical process, or interruption of reaction or process. EFFECT: higher reliability of device and economic efficiency of process. 15 cl, 9 dwg
