Industrial Grade Extruder Machine has a cool starting defensive control device to prevent gear box, motor and screw safety and the machine will start only after achieving the preset temperature to avoid damages to the screw and gear box, motor orchestrated control for pelletizer motor and extruder motor for unchanging element size avoid over feed or under feed to the pelletizer. The Machine is suitable for LLDPE, HDPE, MDPE virgin as well as used in recover and compounding persistence and is available in capacity starting from 40 kg/ hr to 300 kg/ hr. The Machine has air knife for moisture free strands and effectual cooling off the strands and pellets and has feeding hopper that display low level indicator. The Machine has the feature that auto tripping system is available in case of excess feeding. The Machine has screw and drum designed for dissimilar l/d and density ratio considering density and melting temperature of the polymer to be treated. The Industrial Grade Extruder Machine has helical gear box for care free round the clock working and is made with heaters for energy competent heating system and temperature control by microprocessor based digital control system.
