INTAKE AND PRE-CLEANING
Pre-cleaning separator type PSVT(R) 50
Pre-cleaning separator type PSVT50 is used for cleaning and grading of dry and gravity flowing materials by means of a set of sieves (small and coarse admixtures) and cleaning in an air stream in an aspiration case (dust and liftings). The machine works with a closed circuit of cleaning air and limited air exchange from the machine outside. These machines are usable mainly in pre-cleaning sections of flour mills but they are suitable also for other processes where grainy materials should be cleaned, graded and cleaned from fine and coarse admixtures.
Benefits
- Low electric power consumption
- Closed cleaning air circuit
- Simple replacement of sieves
- Separation of three kinds of screenings of different bulk weight and size
- Reliable operation without permanent attendance necessary
- Easy visual checking of the machine operation
- Simple adjustment - screen inclination, throw angle (set angle of vibromotors), oscillation amplitude and circulating aspiration of air sifting intensity within the air sifter can be easily set to the user’s request
Description of the machine
The Pre-cleaning Screen Separator is a machine consisting of the Screen Separator PSVT 50 and the Air Sifter AS 7 with aspiration air recirculation and built-in magnet separator to remove ferromagnetic objects.
The Screen Separator PSVT 50 consists of a frame and a straightly vibrating screen suspended in the frame with inlet and outlet chambers. In the screen there are sieves clothed with perforated sheet (upper sieve) and wire cloth or, for special applications, with full sheet (bottom sieve). The screen oscillation is excited by two attachment vibration exciters.
The Air Sifter AS 7 is a machine working with an enclosed air circuit. Its inlet end is connected directly to the screen separator. It consists of a magnet plate, aspiration chamber with control means for the air sifting intensity control, separating chamber with a worm discharger and an air lock, a built-in fan with air channel and grain outlet with a packing counterweighted flap.
