In the briquetting process of various finely dispersed materials using auger pressing method, an important issue is extending service life and repairing worn-out elements, such as auger, die, lining. This study provides a literature review industrial experience in parts presses. It formulates main approaches for restoring abrasive surfaces presents results experimental studies aimed at prolongi...

The mechanisms of expansion and shrinkage behavior the briquettes coal or torrefied biomass were investigated by measuring weight loss briquettes. In case biomass, particularly large occurred at temperatures below 600°C. hot briquetting, was small briquetting temperature, suggesting that originated from relaxation residual stresses during process. When blended, maximum strain slightly close to ...
