Basket Extrusion
Basket Extrusion General

The basket extruders are not part of the family of screw extruders. These basket extruders have a vertical rotating shaft with 4 extrusion blades located inside a cylindrical screen. The basket extruders are fed through a hopper located above the cylindrical screen while rotating pressure blades assist the material flow into the extrusion zone.

The basket extruder requires a very limited amount of energy to push the material through the screen, resulting in granules with a relatively low density and hardness.
