X(S)K-160 Rubber Lab Open Mixing Mill

A Lab type rubber two roll open mixing mill is specially developed for rubber lab mixing purpose. Our this lab two roll open mill is designed and made at high standard level,harndened gear reducer,bearing system, motor and reducer are directly coupled connection, ensuring the operation sound is very low, and machine is durable to use. Many big tire factories such Yokohama and big rubber parts producers such as Zhongding Group (the biggest rubber parts producer in China) are using our lab type open mixing mill for their sample trial or development of new rubber products.
