data from the roll mill, such as its power uptake, may also be of interest with a view to further process automation. Methods for extruding rubber are being developed and optimised. The key topic of hardware technology in rubber extrusion will be discussed below, with particular reference to the long-established technology of the pin-type extruder.
Products > Three Roll Mills > Three Roll Mill How the Three Roll Mill Works. The material to be milled is placed between the feed and center rolls. Each adjacent roll rotates at progressively higher speeds. For example; the feed roll may rotate at 30 rpm, the center roll at 90 rpm and the apron roll at 270 rpm.
