Are engineered to score over the conventional mills used for mixing of polymers between 2 rotating rolls in terms of higher efficiency and improved machine life. The transmission by 3-stage helical reduction gear box connecting drive motor to the rear roll coupled with anti friction roller bearings instead of bush bearings result in a substantial reduction in power consumption. Another futuristic feature on our mills is the optional addition of hydraulic sensing circuits incorporated for roll loading records of different batches / compounds.
