Extruder Screw Applications

Extruders are frequently employed in the industrial production of plastics, food and cosmetics. In addition to simply constructed single-screw extruders, double and multi-screw extruders require complicated gears in order to drive extruder screws rotating in the same or opposite directions.

Ever more sophisticated extruder forms require gear technology capable of evenly transmitting high torque levels to all worm shafts within a confined installation space. The actual torque at the screws and its exact distribution between the individual extruder shafts can be precisely measured with the help of sensor telemetry from Manner.

Now you can finally answer critical questions in respect of your extruder operation such as:

• What torque levels must the screws actually cope with?
• Is the load distribution evenly distributed across all the worm shafts?
• Can the extruder controller be better adjusted to the actual torques and forces?
• How do the extruder and its individual worm shafts behave under the different production conditions?

We apply your coupling sleeves to the drive shafts with Manner’s tried and tested technology for extruder shafts and the sensor system measures the real torques at the points where they actually occur. The data is transmitted on a non-contact basis via an induction antenna to a corresponding evaluation unit, your computer or controller. In addition, a specially developed software records the measured values, for example for long-term monitoring.
