Power Sifter
Boost efficiency with S. Howes’ centrifugal power sifters.
High capacity Centrifugal Power Sifters separate clumps from desired material by means of rotating paddles which push material through a sieve screen. Numerous screen cloths, mesh and wedge wire screens (for more abrasive materials) are available to achieve capacities as high as 100,000 lbs. per hour. Sifter throughput capacity is dependent on product density, characteristics, and screen size.
Our Power Sifters feature a heavy-duty construction build and low horsepower requirements for reliable and efficient processing of a variety of bulk solids products. Five models are available in mild steel or stainless steel for sanitary applications along with custom power sifter options.

Power Sifter – FAQs
What is a centrifugal power sifter?
A centrifugal power sifter separates clumps, oversize particles, and contaminants from bulk materials using rotating paddles that push material through a cylindrical screen.
What materials can power sifters process?
Power sifters can process powders, flour, sugar, plastics, coffee, milk powder, pet food meal, chemicals, and other dry bulk solids.
What are the advantages of a power sifter?
Power sifters provide high-capacity screening, low vibration operation, quick screen changes, and efficient deagglomeration of materials.
Can power sifters handle abrasive materials?
Yes. Optional wedge wire screens and heavy-duty construction are available for abrasive processing applications.
What applications are power sifters commonly used for?
Power sifters are used for scalping, classification, de-dusting, de-watering, and deagglomerating bulk materials in industrial processing lines.
