FIELD: process engineering.
SUBSTANCE: invention relates to construction, particularly, to ceramic tile extrusion. Proposed extruder comprises metal housing and elastically deforming membrane rigidly secured thereto at multiple preselected attachment points so that tight mid-chamber is formed between said membrane and metal housing to contain incompressible liquid. Rigid bushes are fitted into elastic membrane. Each bush is arranged in the zone membrane is attached to housing in to form valve inlet that enters elastic membrane to interact with ambient medium via a system of release valves made in metal housing. Each said rigid bush comprises closing appliance that breathes air but prevents, at least partially, passage of ceramic powder.
EFFECT: higher wear resistance.
