• The Grizzly Screen is particulary strengthened in order to withstand the difficult feeding conditions in primary screening.
• The vibrating part or "carcass"" is based on a fixed frame by the mean of elastic suspensions isolating the carcass while leaving it oscillate.
• The vibrator mechanism has 1 to 3 high speed turning shafts. Each half-turn, these shafts cause a shock produced by the centrifugal force developed by counterweights.
⇒ The grizzly screen is generally made up of grizzly in special steel anti abrasion in the first deck.
Many panels are mounted staggered to provoke the fall of blocs and make easier the separation of fine products.
⇒ In the second deck, it is constituted of high resistance steel grids to remove fine materials.
