Ami Roto-sifter - High Capacity Gyratory Sifting Unit | Ideal For Hygienic Products, Up To Four Separations

The AMI Roto-sifter has high capacity yet physically small sifter unit used for seperation of various size fractions of particulate materials produced in the Food, flour milling, feed, chemical pharmaceutical, plastics and similar processing industries.

The machine is capable of making up to FOUR separations with a variety of internal flow schemes and option of 4, 6 or 8 Frames for capacity.

It is ideal for Hygienic Products and sieving of large quantities through fine apertures of Silk, Nylon, Polyester or Wire Mesh - Sieve Cloth.

METHOD OF WORKING

The entire stack of sieves is gyrated on a horizontal plane. Immediately the Feed spreads evenly over the top sieve. The rotary movement of the machine conveys the stock on the sieve and some of the finer particles fall through the screen onto the sieve collecting tray, to be discharged at right angles into one of the THROUGH channels. Thus material Travels overthe sieve and falls on the top of the next sieve below which similar size seperation takes place.

The coarse material or overtails continue to travel overthe remaining sieves, turning over and reversing their direction of flow as they pass from sieve to sieve, until it reaches the bottom sieve from where oversize is discharged as TAIL product. During the sieving operation, the mesh apertures are kept constantly open by the action of cleaners bouncing against the holes of the underside of each sieving surface.
