OPEN MILL MIXING ON TWO-ROLL MIL RUBBER

Jul 20, 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.

Two roll rubber mill - Wikipedia

Natural rubber, which is harvested from a rubber tree, hevea brasiliensis is the base for many rubber compounds made using a two roll rubber mill. Rubber trees are tapped to remove the latex that is stored in their trunks. This material can then be mixed with additional ingredients to create rubber. Other natural sources of rubber are obtained from the Sapotaceae and Palaquium trees native to the Malay peninsula, as well as the Mimusops globoosa tree native to Panama. Synthetic rubbershave also been created an
