The Wear on Roller Press Rollers Made of 20Cr4/1.7027 ...

Our experience shows that the wear of rollers is greatly influenced by the properties of the briquetting material, especially the external friction coefficient, hardness, and abrasive properties. The actions aiming at accurate identification of wear mechanisms and also the intensity of these phenomena over time need to be accurately understood and accurately verified using real objects.
