    HistoryOperationRubber compounding

    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 rubbers have also been created and are also used to create rubber compounds.

In the 1830s, Edwin Chaffee developed a technology similar to the two roll rubber mills that are used in rubber production. His machine included multiple rollers that were used to flatten rubber into thin sheets. Chaffee then created the two roll rubber mill which shears and mixes the rubber by having two rolls rotate in opposite directions, at different speeds. The two roll rubber mill is used in almost every rubber production facility today. Many other inventors created rubber mills with varying degrees of similarity to Chaffee's initial designs. George Watkinson patented a three roll design in 1894 while Harold Denmire patented a four roll design in 1932.

  • Three roll mill Wikipedia

    OverviewOperation of a three roll millApplication

    A three roll mill or triple roll mill is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it. The three-roll mill has proven to be the most successful of the range of roll mills which saw extensive development in the 19th century. These included the single-roll mill and the five-roll mill. The single-roll mill works by material passing between the roll and a fixed bar pressing against the roll. The fiv

The three-roll mill has proven to be the most successful of the range of roll mills which saw extensive development in the 19th century. These included the single-roll mill and the five-roll mill. The single-roll mill works by material passing between the roll and a fixed bar pressing against the roll. The five-roll mill incorporates four successively smaller in-running nips and hence, compared to the three-roll mill, allows the use of larger agglomerates as part of the input material- but is correspondingly more complicated and expensive.
