Frequently Asked Questions

What is the two roll mill process?

The two roll rubber mill processes natural rubber into various compounds. Two horizontally opposed stainless steel rolls rotate in opposite directions at different speeds to mix rubber and ingredients, creating rubber compounds through mechanical shearing action.

What is the principle of roller mill operation?

Roller mills utilize stress applied by rotating wheels and attrition to process solids in suspensions, pastes, ointments, and solid materials. The rollers rotate at different speeds, shearing material as it passes through the gap between them.

What is the friction ratio of a two roll mill?

The distance between mill rolls (nip) can be varied, while the speed difference between rolls is called friction ratio, enabling shearing action. Typically, the back roll moves faster than the front roll, with common friction ratios around 1:1.25. This open mill mixing process is essential for rubber compound preparation.
