I am processing a PP with higher content of caolin (wire) and suddenly my extruder stops of transporting material, increasing speed screw and interrupting the process (I control the rotation of the screw through the exit pressure). Can that problem be attributed to the waste of the machine?

I would look at feed interuption at the feed throat if you are using a blend of polymer and mineral. A starve feeder would be the best solution.
