Sieve bend screens are widely used for separating different grades of coal and recovery of fine coal particles in coal mining industries. The sieve bend screen is commonly placed before the vibrating screen to improve efficiency. Mainly for coal washeries moving the material to be pre-dehydration, mud, off-mediated job, classification of slime recovery. Sieve bend screens are constructed with V type profile wire, the screen slot is narrow in the above and wide in the below, gives the screen good non-clogging properties.
Basic Principle
Sieve bend screen is an economical and practical solid-liquid separation equipment. The coal slurry flows down the curved screen, The screen constructed by stainless steel v shape profile wires, the unique wire sharp provides a sequence of edges for cutting the flow. The water with small particles falling through the screen slot, while larger particles are retained on and continue down the screen surface.
