Ferro Silicon Fine Screening

Llambec was approached by a company who produce Ferro Silicon for Densification purposes. Screening Ferro Silicon at micron sizes below 200 efficiently has always being a major problem resulting in Low capacities, efficiencies, and high maintenance costs. Llambec technology replaced the existing circular Motion Screens used in the industry and after lengthy trials, tests and modifications produced the very first Kinetic Driven Multi-Deck Sizing Screen now in operation in the Gauteng Province in South Africa. The units now in operation have the following specifications

 

Llambec Technology’s brief was to produce an innovative Screen which could improve on existing efficiencies, reduce recycle oversize , minimize oversize in undersize,  be more maintenance friendly, lower power needed to drive unit and to dust enclose. The Kinetic Multi-Deck Sizer has achieved all these plus others not mentioned. Capacities are dependent on Screen width from 500mm wide to 2500mm .
