20-7-2013 Set the roll nip opening to 2 mm. Adjust and maintain roll temperature at 70 ± 5 degrees C. Add rubber into the mill nip and band, as a continuous sheet, onto the front roll. Using a hand knife, make two ¾-cuts from each side and allow the rubber to move through the nip quite a few times until a smooth rolling bank is formed on the nip.

A laboratory two-roll mill is used to hand-process plastics and the like. It looks like an old fashioned "wringer" from a washing machine mounted horizontally, but it isn't. The rolls counter-rotate, to be sure, but they do so at different rates to create a shearing action in the trough formed between them.
On the other side when the good temperature control or maximum cooling effect is required the peripherical drilled rolls are the only suitable alternative.

It features individually controlled roll temperature and speed which improves blending efficiency. It also has easily adjustable bronze side dams contain the melted compound within the roll face working width. Our Laboratory Two-Roll-Mill has been designed with high-loading capacity while still offering quick roll opening on E-stop.
Open mixing mill: A mixing mill consists of two hollow metal cylinders (rolls) placed horizontally and rotating towards each other as shown in Fig. 1. The two rolls are revolving with different speed where front roll rotates slower than the back roll. The difference in speed of two rolls is called as friction ratio.
Preparation of SBR/RR Vulcanizates Mixing of fresh SBR, various proportions of reclaim rubber and compounding ingredients was carried out for 15 minutes at room temperature on an open two-roll mixing mill. Compound formulations are presented in Table 1.

The rolls counter-rotate, to be sure, but they do so at different rates to create a shearing action in the trough formed between them.
The mill consists of two closely spaced parallel, horizontal rolls made from hard castings supported by strong bearings in a mill frame. The counter-rotating rolls are driven at different speeds to maintain a friction ratio of 1.05 to 1.25, transporting the rubber over the top of the roll to the nip area, then through the nip with small ...

The two rolls of the rolling mill rotate in the opposite direction. For the purpose of mixing, one roll runs faster than the other one (friction). Therefore, shearing forces act on the rubber in the nip between the two rolls. In this way, the rubber is mixed. Structure of a mixing mill. A mixing mill consists of two rolls arranged in parallel ...
