Forming feed material into rounded pellets by controlled centrifugal and rolling action.
Wet granules are fed onto a rotating centrifugal disc while air passes through the annular gap. Centrifugal force, air lift and gravity create a rolling, rope-like movement that rounds the material into pellets.
