Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around ...

WhatsApp: +86 18838072829The basic function of the three roll mill is a differential speed between the three rolls. The difference between the second and the third rolls is two to four times higher than the difference between the first and the second rolls. The dispersion takes place in the second nip; the first nip regulates the feeding of the second "dispersing" nip.
