The FA type of cyclone screener is directly used in the pneumatic conveying stream for safety screening and fractionating of material, for eliminating foreign matter, breaking lumps, and for lifting/loosening product.
The pneumatically conveyed product enters the screen casing via the suction spigot. The bulk material is then taken over by the intake distributor with fluidizing bars, and gently whirled through the screen basket. The fine material drops through the screen into the outlet for fine product and enters the system below via the suction hopper. At the outlet for coarse product the coarse material is removed from the system and collected in a hopper. The filling level of the coarse material hopper can be controlled by a sight glas. The special extraction device with snap locks allows simply extracting and swivelling the screen basket to the side for inspection. This makes for thorough inspection and quick exchange if necessary. Safety relevant connections are governed by electric protective devices (safety switches) which switch the machine off the moment such a connection is opened. The screening mesh is held by rings, can freely vibrate, and thus cleans itself. The built-in baffle prevents too much fine product getting into the coarse-product outlet.
