Abstract: Abstract: With the progress of science and technology and coal preparation industry demand, a large number of new equipment is developed or referenced to coal washing and screening process, increases the coal preparation process flexibility and the diversity of coal preparation equipment, bring new vigor for coal preparation industry's vigorous development. Derrick high frequency vibrating fine screen as one of the equipment, is introduced to the coal preparation plant get a good application in recent years. The paper mainly introduces the derrick high frequency vibrating fine screen structure, principle, characteristics, screening efficiency and the successful application to the coal preparation plant coarse coal slime classification, desliming process of the case. Keywords: Derrick high frequency vibrating fine screen; Coal preparation plant; Coarse coal slime; Classification; desliming
