7. How to Select the Right Twin Screw Extruder for Your Operation
Selecting the right twin screw extruder for your operation is a critical decision that will have a significant impact on your production efficiency, operational costs, and long-term success. There are several factors to consider when evaluating different extruder options to ensure that the machine you choose meets your specific production requirements and provides the best return on investment.
7.1 Define Your Production Requirements and Capacity Needs
The first step in selecting a twin screw extruder is to clearly define your production requirements and capacity needs. You should consider both your current production needs and your future growth plans. It is generally recommended to choose an extruder with 20-30% more capacity than your current requirements to accommodate future expansion without having to invest in additional equipment immediately.
When calculating your capacity requirements, you should consider the actual operating hours of your facility, the efficiency of the extruder, and the downtime for maintenance and changeovers. Kerke twin screw extruders typically operate at 90-95% efficiency, which is significantly higher than the industry average of 70-80% for traditional extruders.
7.2 Evaluate Material Characteristics and Processing Challenges
The characteristics of the materials you will be processing and the specific processing challenges of your application will have a significant impact on the extruder design and configuration you need. You should consider factors such as material viscosity, filler content, abrasiveness, moisture content, and thermal sensitivity.
For example, if you will be processing highly filled compounds with abrasive fillers, you will need an extruder with wear-resistant screw and barrel materials.
