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.
