What should you pay attention to when mixing natural rubber with an internal mixer?

What should you pay attention to when mixing natural rubber with an Internal Mixer? How much temperature, how to adjust the mixing time, what problems should be paid attention to when adding sulfur and accelerators, how much time is mixing, how to control the temperature? I would like to ask you, is there a temperature that is suitable for the mastication of the mixer, a few minutes of plastic?

The natural rubber of the internal mixer should be above 135 degrees, and the mastication time is based on the viscosity of the raw rubber.

It is troublesome to add sulfur to the mill. I want to add it directly to the mixer. We are a mixture. A method of vulcanization is not acceptable. You can use vulcanization as a separate mixture (ie First make a mix of rubber, and then add sulfur after cooling. The discharge temperature is currently around 80 degrees.

The discharge temperature is around 80 degrees? There is no problem with pressure and fill factor? Is the effect of mixing rubber getting better? It's also possible that your cooling system is surprisingly good.

The displayed temperature is not accurate, it can not be 80 degrees, you can test it, see if the mixer is sulphur or not.

If the rubber door is low, more than 80 degrees is also possible, after all, the speed is slow.
