Llambec was approached by a company that produces Ferro Silicon for Densification purposes. Screening Ferro Silicon at micron sizes below 200 efficiently has always been 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 of South Africa. The units now in operation have the following specifications
Llambec Technology’s brief was to produce an innovative Screen that could improve on existing efficiencies, reduce recycle oversize, minimize oversize in undersize, be more maintenance-friendly, require less power to drive the unit, and be dust-enclosed. The Kinetic Multi-Deck Sizer has achieved all these plus others not mentioned. Capacities depend on Screen width, from 500mm to 2500mm.
