To increase the through-put rate of a granulator used for size reduction of loose, unpressed plastics a force feeding technique was developed.
A screw conveyor is utilized for a technically optimized material feed.
Via conveyor the material is fed in the feed hopper. The transport to the grinding chamber is now no longer only based on the principle of gravitation – in fact the material is now fed to the grinding chamber by one / or more vertically assembled screws. Depending on the required granulator size the number of screws, the rotation speed as well as the drive capacity can vary.
