Trident Screw Press

The Trident Screw Press is a durable, robust and efficient piece of equipment, purpose built for making bedding material from dairy manure. The press features a screw with interrupted flighting, graduated pitch and resistor teeth. The flighting is notched and a 1/32 inch screw-screen clearance further promotes effective dewatering and low maintenance operation. The screw shaft is supported on both ends ensuring robust and low wear operation. A simple yet effective shaft seal design prevents ma- chine failure from manure liquid entering the gearbox. An air operated outlet door allows automated output control. The produced solids are coarse and fluffy with up to 34% dry matter, providing both cow comfort and excellent drainage characteristics required for use in today’s modern dairies. The equipment with its robust construction and corrosion resistant components is designed for long lasting operation, while reducing maintenance and operational costs.
