Using polymer antiadhesive sheets as a method to reduce ground adhesion to working bodies of digging machines

Abstract

The analysis is carried out for using polymer antiadhesive sheets in order to reduce adhesion of wet cohesive soil to working bodies of digging machines when operating under sub-zero temperatures. When extracting thawed mine rock under subzero air temperature, intensive freezing of cohesive ground to contacting bucket surfaces, pickup apparatus elements, conveyor belts, treating facilities and links takes place. An experiment was held using PPL-EI and PPL-UI polymer coatings. After mathematic analysis of experimental results regression equations were obtained, which were applied to engineering solution of excavator bucket.
