An expeller arm in the oil palm industry is a mechanical arm or lever used in the screw press system to apply force on the back-pressure cone or adjust press resistance. It helps regulate pressing pressure, stabilize oil extraction, and ensure consistent flow of pressed fibre (cake).

Product Description
The expeller arm is a key component of the palm oil screw press assembly, responsible for supporting and controlling the movement of the back-pressure cone (or cone cylinder). By adjusting the applied tension or pressure, the expeller arm ensures the screw press operates at optimal pressure to maximize oil extraction while maintaining stable throughput.
