Hi

I am trying to process a recycled nylon but it tends to have a lot of oil in it and the loading is inconsistent. We are using single screw extruders and I have been advised that a suitable mixing zone on the screw may help. Does anyone know any contacts in the UK who may be able to help?

Is your mixing prolem distributive or temporal? If distributive, perhaps a Kenix type of mixer would be most inexepensive to try first. If temporal, as it sounds, then a screw mixer would probably be able to help, but this is a much more difficult situation. If the inconsistancy is drastic, then you might need to do some pre blending as a batch.

There are many sources of different types of mixers, and most claim to perform well. Perhaps you can identify one who has experience with the oil loading problem.
