Material Load:
– impact rails: absorb the force of material loading and protect the roller bearings
– the plates flex under the loading shock, discharging the force on the frame through the impact rails, thus protecting the roller bearing
– once the material is loaded, the plates are stiff enough to flex back and proceed supported by the rollers without contact with the impact rails
Plates:
– thick steel sections forces the material to follow the plates even during the hardest extractions under a full hopper
– the anti-spillage lip is in special armoured steel and ensures continuous contact between two adjacent plates, minimisibg material spillage
Wheels and chains:
– drive wheels are made in high alloy steels with replaceable toothed segments
– the parts in contact with the chain are induction-hardened to extend their operating file
– the chains with pins and fixed bushes are in high alloy steel, induction-hardened on the wear surfaces
Pins and bushes are tempered to ensure a very long wear life
A complete range of strong apron feeders is available for the heavy duty extraction of material from hoppers under waggon tipper or truck unloader.
The Apron Feeders are designed for robustness and effectiveness of processes: they can reach over 3600 millimeters ub width; the pans ae built in tick steel profiles, reinforced with beams, with a shock absorbing systems that protects the bearing of the rollers from the impact shocks
They can extract hoghly abrasive materials with grain size up to 1500 millimeters. They can be fully dismountable to be retrofitted into your existing bunkers
