Continuous Operating Mixing Machine Function Mixing is one of the important parts in rubber product processing. So far, the most common technologies have been used are open mill mixing and internal mixer mixing, which are called non-continuous mixing. , We have designed the "screw mixing machine" in continuous leveling method and of high efficiency with the strong points as follow: It is efficient as it works long; It does not result in power wasting as there is no idle-running; It does not result in any working environmental impacts as the the transaction in the sealed main body of the machine; It reduces the cost and increase the profit in operation as less power and fewer workers are required compared to those for open mill or for internal mixer. It takes low labor intensity as there is only one worker needed in material feeding on the conveyor and qualified product is processed automatically. It is a new type of mixing machine which is highly recommended in rubber product processing.
