ABSTRACT:
A conical-bottom silo, particularly suitable for small-sized pieces of plastic material with properties of high elasticity, includes a conical screw stirrer inserted axially in the conical bottom of the silo. The conical screw of the stirrer is discontinuous and divided into several sections. The silo has a structure for discharging the material arranged below an outlet port positioned laterally in relation to the stirrer and including two co-operating cylindrical screws. The stirrer can be provided with apertured grill outlets for heated, forced air.
