PMS CENTI SIFTER® is an innovative mechanical screening which offers high efficiency and throughput in various bulk solid processing for non-abrasive and non-friable materials.  Its functions can be categorized into Scalping, Policing, Separation, Classification, De-agglomerating and Conditioning. The sifters are widely used in pharmaceutical, chemical, food, agricultural, plastic, chemical and agricultural industries.

Theory of Operation

During the operation, material is fed by gravity into feed screw, which conveys it to the cylindrical sifting chamber.  As it enters the sifting chamber, rotating blades continuously propel the material and accelerate the movement of the material against the screen, ensuring a gentle but efficient sifting action.  By its nature, centrifugal sifter provides excellent material distribution over the screen periphery, allowing a small area of screen to handle very high material load.  The paddles also function to breakup soft agglomerate.   

The desired-size particles passed through the screen are collected at the main discharge port.  Meanwhile, particles larger than the screen aperture gradually progress along the axis of the screen and are expelled through oversize outlet spout.    

All contact parts are made of stainless steel SUS 304, mirror finish.  The motor bearings and mechanical parts are located outside the process area, avoiding contact with the product. Secured inlet and outlet ports ensure dust tight operation.  Several options are also available upon specific request.
