FIELD: process engineering.
SUBSTANCE: invention relates to emulsification of oil and water for preparation of water emulsion of gluing agents for bulk or paper and cardboard separately. Continuous phase is fed at pressure through Venturi nozzle into mixing chamber. Disperse phase is optionally fed at pressure in Venturi nozzle mixing chamber. Emulsion produced in mixing chamber is forced through mixed phase nozzle and from Venturi nozzle. Venturi mixed nozzle diameter is larger than that for continuous phase at the ratio higher than 1:1 and lower than 4:1.
EFFECT: stable gluing emulsions, stable operation of apparatus and efficient gluing.
