Technical Questions & Answers
\n
\n
What is the two roll mill process?
\n
The two roll rubber mill processes natural rubber into various compounds using two horizontally opposed stainless steel rolls that rotate in opposite directions at different speeds to mix rubber and ingredients.
\n
\n
\n
What is the principle of roller mill?
\n
Roller mills use stress applied by rotating wheels and attrition to process solids in suspensions, pastes, ointments, and solid materials through shearing action in the gap between differentially rotating rollers.
\n
\n
\n
What is the friction ratio of a two roll mill?
\n
The friction ratio is the speed difference between rolls that enables shearing action, with the back roll moving faster than the front roll. Common ratios range from 1:1.25 to 1:1.35, facilitating open mill mixing operations.
