### Introduction to rubber processing and safety issues

A powered ram or floating weight in the feed throat forces ingredients into the mixing chamber, which is usually water-cooled. The mixed compound is discharged via a sliding or hinged door below the mixing chamber, usually onto a two- roll mill, roller die, twin-screw extruder, conveyor, skip hoist, or .

### Shear force - Wikipedia

Shearing forces are unaligned forces pushing one part of a body in one specific direction, and another part of the body in the opposite direction. When the forces are aligned into each other, they are called compression forces. An example is a deck of cards being pushed one way on the top, and the other at the bottom, causing the cards to slide.

### Rolling of Steel in a Modern Long Product Rolling Mill ...

Jun 19, 2017· Modern long product mills normally use tapered roller bearings for rolls since these bearings can support both radial and axial forces due to the inclined position of the rollers. Four-row and double-row tapered roller bearings are used in rolling mills.

### Three Roll Mills for Laboratory Mixing and Blending

Three Roll Mills. 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. Material is transferred from the .
