Abstract

A batcher for granular materials comprises a plurality of gravimetric hoppers (1) each of which is designed to feed an underlying scale (2) through a respective bottom outlet (3) which is closable by a respective gate (4) driven by a relative actuator (5), a discharge tube (6) being formed below the gate (4) and closable at its inner end by a shutter (7) movable between a closing position, in which it allows the material dropping from the outlet (3) to travel towards the scale (2), and an opening position in which it acts as a deflector to direct the material towards the discharge tube (6).
