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

As regards “abnormal” rolling conditions which are more or less very “normal” for rolling mills roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll failure have to be discussed and determined (or vice versa) to reduce the risk of repeated roll

Rolling of Metals: Process and Principles (With Diagram)

A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product. The metal changes its shape gradually during the period in which it is in contact with the two rollers.

Introduction to rubber processing and safety issues

This refers to mixing operations using horizontal two roll mills. The operator (usually known as a mill man) places the various ingredients in the nip formed between the rolls and mixes the compound by cutting it off the rolls and re-feeding it into the nip until all the ingredients are added. Mills are used not only for blending of
