A brief description of the difference between open mixer and internal mixer

In the rubber industry, mills and mixer equipment are often used when mixing rubber. What is the difference between a mill and a mixer? What are its features? Let's break it down.

The difference between a mill and a mixer:

The mixing amount of the refinery is small, and the various dosages are good to add, because it is open, the heat dissipation is fast, the temperature effect is not so obvious, if the temperature is too high, you can stop refining for a period of time and let it cool before mixing; The amount of rubber mixing in a single mixer is several times that of the mill, and the temperature change needs to be strictly controlled during the mixing process, and the order of small materials addition needs to be controlled.

Moreover, due to the large amount of mixing, vulcanization was also considered in the past, and finally added through the refiner, but later found that it did not work, because the material of a car mixer is equivalent to several truckloads of open mill material, can not be mixed and sulfurized, if the sulfurization is added by the mill, it is necessary to divide a truck of material of the mixer into several truckloads of material to add, but the reality is that this is not possible, because each car of mixed material you can not guarantee uniform mixing, the composition of the split compound recalculated The content is generally uneven and wrong, The sulfur added would also be wrong and unreasonable. Therefore, vulcanization must also be added through the mixing process, where temperature control is more important

What is the difference between an open mill and a mixer? In summary, the most basic difference is the difference in process. The choice between a mill or a mixer when mixing rubber is based on the characteristics of the compound and the needs of the customer.
