Centrifugal Sieves ST / Rotary Sifters


The Beccaria ST range of centrifugal sieves / rotary sifters have been designed to give the optimum performance for the removal of lumps, foreign bodies, and husks from powders, granular or milled products.
This equipment has been designed & manufactured to meet the requirements of ATEX Directive 94/9/EC. All Beccaria rotary powder sifters are certified to ATEX Zone 20 internal and ATEX Zone 21 external.

Principle of operation

Product is introduced through the in-feed hopper at one end of the sieve. A central shaft of a cantilever design runs through the centre of the machine supported by bearings at one end only. This design makes it very easy to strip-down and clean this machine. The first portion of this shaft has a screw to move product into the sieving cylinder. Mounted on the second half of the shaft are four paddles which press the product to be sifted against the mesh.
As the paddles rotate the tumbling action breaks apart agglomerations reducing product wastage. The sieved fraction exits through the outlet underneath the main drum whilst the oversize particles exit through the outlet at the end of the sieve.
