FIELD: metallurgy.
SUBSTANCE: invention refers to foundry. The procedure consists in sedimentation of binding on surface of sand in a fluidisated layer. Binding is settled in the fluidisated layer, fluidised agent of which corresponds to binding in form of mist.
EFFECT: increased dry strength of mixture due to uniform distribution of thin film of binding on sand grains.
