VideoSifters - Rotary
Nu-Con rotary sifters are designed for classifying, scalping or delumping duties on dry powders or granules.
Options
There are 4 standard sizes in the range. Each size has designs for either a metered gravity feed or an in-line arrangement for installing directly into pneumatic convey lines.
Operating Principle
The material to be sifted is fed into the stationary cylindrical screen by means of a screw mounted on the rotating shaft. A series of paddles which rotate inside the screen without contact, centrifugally force the material against the screen breaking up soft agglomerates. Sub-sieve material (fines) that pass through the screen discharge into a collection hopper at the base of the machine. Oversize material and hard lumps (that cannot be broken by hand) traverse down the length of the screen to the overs outlet. An adjustable baffle plate at the end of the screen regulates the flow of overs.
