Description
The Worm Screw Shaft is a critical component of the EFB Press (Empty Fruit Bunch Press). It functions by compressing the Empty Fruit Bunches (EFB) to extract residual palm oil and reduce moisture content before further processing. This prepares the EFB for efficient use as biomass fuel or organic fertilizer.
🔧 Worm Screw Shaft Features
Engineered for High Compression Force
Enhances oil extraction efficiency by applying consistent pressure to minimize residual oil loss.Manufactured from High-Strength, Wear-Resistant Materials
Made from hardened carbon steel or alloy steel to withstand extreme pressure and friction.Effective Moisture Reduction Capability
Lowers the moisture content in EFB, making it suitable for combustion or composting applications.Long Service Life for Continuous Operation
Designed for high-throughput palm oil mills with demanding, non-stop production cycles.
🔩 Types of Worm Screw Shaft
Standard Worm Screw Shaft
For general-purpose EFB presses with standard production capacity.Heavy-Duty Worm Screw Shaft
Built for high-compression applications and continuous heavy-duty operation.Custom-Made Worm Screw Shaft
Tailored designs for specific press models or unique operating conditions.
🏭 Applications of Worm Screw Shaft
Palm Oil Mills – Extracts remaining oil from EFB and prepares the material for further use.
Biomass Power Plants – Reduces EFB moisture content to improve fuel efficiency.
Organic Fertilizer Plants – Prepares EFB for composting by reducing moisture and improving fiber structure.
✅ Advantages of Worm Screw Shaft
Minimizes oil loss from EFB, improving overall oil recovery rate
Reduces moisture for more efficient downstream applications
Highly durable under high compression, friction, and impact conditions
Easy to install and maintain, minimizing operational downtime
