In coal preparation, screening machines serve two purposes: sizing and media recovery. Oftentimes, the initial screening is performed by a scalping screen located outside the plant. This prevents the screens inside the plant from becoming overloaded. The deslime screens make the next cut and most prep plants size to minus 1 mm.

Mining vibrating screens are widely used for coal mine washing and processing in China [1,2]. Due to di cult working conditions and long-term alternating loads, spring permanent deformation failure of the spring may occur, and this leads to a decrease in spring sti ness. Mining vibrating
