Controlled feeding under a dump hopper and removal of the fines from material can be made with the same machine, the Skako Grizzly Feeder type FGD.
Placed directly under the discharging hopper for Dumpers and fed by material up to 2 meters, the Skako Vibration grizzly feeder type FGD can be up to 10 meters long and have a capacity up to 2000 t/h in standard versions.
Because of their very robust design, with Huck bolt construction, they combine in the same unit, the function of pre-screening and feeding crushers, or any other equipment. The feeding area can withstand the static loads of the material and the dynamic stress due to the fall of the lumps.
The pre-screening area is designed with sectional, replaceable anti-blinding grates with fall steps to avoid any pegging and to allow efficient fines removal. For sticky material, a special design with ‘forged rods’ coupled with a high working acceleration, is optionally available.
