In recent years, EVC bottom bin activators have successfully replaced the draw-off belt feeders under main storage silos. Silent, reliable and maintenance free make these units the preferred choice in modern foundries.

The machine is composed of a vibrating group, of conical trunk shape with an inclination of 30°.

Complete with fixings for mounting the vibrator motor with eccentric masses and the central discharge outlet. It is fixed to the mouth of the storage silos by tie rods installed at regular intervals, and equipped with elements absorbing and damping vibrations. A flexible toroidal ring ensures an absolute seal between the static part and the vibrator. At the discharge mouth is applied a guillotine damper operable, at choice, electrically, pneumatically, or manually.
