Atara Equipment Ltd is the distributor for the Morillon Hydrascrew silo unloading system.

Underneath the turret is the hydraulic motor that drives the shafted spiral and a slide gate operated discharge port.

The spiral rotates clockwise pulling the material towards the turret and discharging below into a shaftless screw transport conveyor, at the same time the turret and spiral rotates around the silo clockwise. Ensuring the first material in is the material that is extracted first.



The pivot type cap is used for material that does not flow freely. The crown cap is used where material flows freely. atara equipment morillon silo unloading  atara equipment morillon silo unloading 

Morillon has designed the system to be able to adapt to an existing sloped silo floor. This design easily removes materials that are prone to bridging within the cone area. The shafted spiral rotates on itself pulling the material towards the center exit, while rotating around the cone.
