Since rolls are the key equipment in seed oil extraction process and presence of impurities in the process could result in damaging the rolls therefore it is of great importance to have rolls with good hardness and shock resistance.
Oil seed extraction rolls are casted both statically and centrifugally with the use of clear chill cast iron for the outer layer and gray cast iron for the core. The journals are made of forged steel which are shrink fitted into the roll depending on the application. To overcome the machine vibration all rolls will go through a balancing procedure and depending on customer's request, wear resistance rings could be installed on each side of the roll.
Finishing jobs on the surface are depended on the customer's request and it could be grinded, fluted or sand-blasted.
