Bibby’s UEP Modular Torque Limiter Provides Maximum Protection Against Overloads On Twin Screw Extruders & Mixers

The UEP modular torque limiters are the result of over 30- year’s experience in arduous applications, particularly in the steel industry, mining and marine industries. Designed specially for use on twin screw extruders and mixers, they offers users the key benefits of simplified installation, very accurate release torque repeatability - achieved with minimal variation between static and dynamic release, simple fast manual re-engagement and low cost maintenance.

The Bibby UEP limiters are convenient individual modules which are factory preset to provide the required release torque. The benefit of this modular system is that downtime can be kept to an absolute minimum, using spare pre-set modules that are held in stock as immediate replacements for when overloads occur, at any time of day or night.

The optimised design of the UEP torque limiters also means that installation is highly flexible, enabling the centre section of the torque limiter to be removed without the need to move the extruder motor or gearbox. Similar design versatility ensures that any maintenance of the modules is a straightforward operation, and that recalibration is a simple removal operation achieved without having to replace the complete torque limiter unit.

Whilst each torque limiter assembly is normally factory preset, site adjustments can be carried out, if required, and a setting chart with instructions is provided for this purpose. A security key is required for this operation and adjustment should only be carried out by authorised personnel.

Manual reset of the torque limiter can only be carried out when the drive is at rest. Switching the drive off following an overload is accomplished by proximity sensors (customer supplied), which are used in conjunction with sensor targets that are included with the UEP package. Resetting is achieved by realigning the two halves of the unit, and then lightly tapping each module fitted, with a soft mallet.
