Cantilever Centrifugal Sifter Principle of Operation
ApplicationsKek Centrifugal Sifters are ideal for the following powders:
• Food/Dairy - powder, mixes, additives, granules, crumbs, spices and dehydrated products
• Pharmaceutical - powders and granules
• Plastics - powder, resins, and paints
• Chemical - powders, granules, additives, resins, dyes, pigments and metals
• Any application requiring highly e�cient sifting, frequent cleaning and no cross contamination between batches.
Kek Centrifugal Sifters are ideal for the following applications:
• Scalping to remove oversize particles
• Policing to remove foreign particles and objects
• Size classification of powders
• De-lumping and de-agglomeration of powders
• Liquid Straining
Material is fed into the sifter inlet � and is accelerated by the auger �. The auger moves the material into the cylindrical sifting chamber where it is picked up by the rotating paddle/blade assembly � and thrown against the sieve screen �. The blades � on the paddle assembly are set in a helical configuration to move the material along the entire length of the sieve screen at the optimum sieving rate for any particular application. The fine product � passes through the screen and is collected at the main sifter outlet �. The oversized and/or tramp material is moved to the end of the sifter chamber and, after passing around the end baffle, is discharged through a separate smaller outlet �.
