BOCOMATICy extrud e r EB 40 laborator extruding machine for rubber mixture The BOCOMATIC EB 40 laboratory extruder with type designation EB/N-40/14-4/33 is an extruding machine intended for specific or experimental production for detection of material defects or contingent impurities in the undercured rubber mixture. The output mixture output is reduced through a extrusion head in the form of desired profiles (e.g. strips with dimensions 50x0,8 mm etc. according to customers requirement). The extrusion head is equipped with air cooling. The principle of the extruder is a closed steel supporting frame with storage area which is possible to close. In the frame are placed electric and control case equipped with NORD/OMRON electric components with OMRON (PDI) digital thermoregulators, NORD gearbox with an axial bearing housing, main NORD (3x380V/ 50Hz) three phase asynchronous electric motor with stepless rpm regulation, controlled by NORD frequency converter with external cooling. The screw is delivered in two versions – not tempered (without drilled aperture) and tempered (with aperture, bored in its whole length) intended for cooling by water. It is possible, on customers request, to fur
