Are available in four different types: Straight & Helical
Corrugated, both either in Open or Closed Ends.
Corrugated roll shells are the most popular throughout
the pelleting industry due to the fact that they reduce
slippage of materials and offer resistance to plugging
Numerous "Dimples" are drilled into the roll surface which

These shells are covered with an adhesive mixture of
carbide particles, thus having the ability to
traction, and are long lasting.
