Comparative test of SFY-C fully automatic screening granulometer

Screen analysis is one of the sediment grain size analysis methods.The newly imported SFY-C type sonic vibrating and fully automatic screening granulometer makes use of sonic vibration to force air to move in an enclosed box cavity with overlapped screens in it,and the vibrating air causes the sample sediment grains to move periodically and vertically,resulting in little plugging of screen openings.The granulometer also makes use of the vertical beating of electro-magnetic beaters to disperse dumplings of sediment grains and to reduce abrasion and breakage of sediment grains,greatly raising the efficiency of screening.The granulometer is reliable and applicable,and has high accuracy and good stability.Since it has a Windows operation interface,its operation is convenient and is highly automated.The data processing has been computerized,so that the sediment grain size analysis is developing toward automatization.
