The calculation of an extruder screw throughput is a fundamental parameter to determine the amount of plastic material processed and extruded per unit of time. Throughput is expressed in kg/h and depends on several factors, including screw design, the type of material used, and the operating conditions of the extruder.
Key Factors Influencing Screw Throughput:
- Screw Diameter: A larger diameter allows for more material to be transported per rotation, increasing throughput.
- Rotation Speed: Increasing the screw rotation speed boosts the material flow, but care must be taken not to exceed operational limits to avoid overheating or compromising product quality.
- Channel Depth: The depth of the screw channel determines the amount of material that can be transported with each turn.
- Material Rheology: The viscosity and flow properties of the material influence the screw's transport capacity. More fluid materials tend to improve throughput compared to more viscous materials.
How Does Bausano Handle Screw Calculation and Design?
At Bausano, we internally design extrusion screws starting from a rheological study of the material the customer wishes to process. We analyze the material properties in detail, and based on this data, we design the optimal screw to ensure maximum efficiency and throughput during the extrusion process.
Subsequently, we test the screws in our laboratory, conducting practical trials to verify performance and optimize the final design. This approach ensures that the screw is perfectly adapted to the customer's material and specific application, delivering excellent performance and a steady, controlled material flow.
With Bausano, every screw is the result of meticulous design, offering customized and cutting-edge solutions. Our extruders ensure maximum production efficiency and precision, tailored to the customer's needs and the specific characteristics of the processed material.
