FIELD: devices for palletizing of materials by extrusion method; applicable in chemical industry for palletizing of pasty materials. SUBSTANCE: extrusion head has body with channel for supply of pelletized materials, hold-down flange and die. Die has forming channels of variable length and convex surface facing supplying channel. Convex profile of die cross-section is made in form of square parabola. Ratio of length of die forming channels to diameter of its convex surface is within 0.1-0.3 and has maximum value in oil center. EFFECT: higher strength and size accuracy of pellets, reduced hydraulic resistance of extrusion head. 2 dwg
