The apron feeders are available with frequency controlled electro mechanical drive ore hydraulic direct drive.

5 Heavy Duty Apron Feeders for Special Applications Besides the standardized apron feeders Tenova TAKRAF supplies heavy duty apron feeders designed to meet special requirements resulting from conditions given by material, capacity and geometry. For capacities requiring chains above D11, please contact TAKRAF GmbH. Following is a selection of TAKRAF apron feeders supplied: Material Description (Width x Centers - Chain) Phosphate PB 2600 x D8 Phosphate PB 2600 x D8 Overburden (hard rock) PB 2400 x D9 Overburden (hard rock) PB 3100 x D11 Primary crushed Copper Ore PB 2600 x D9 ROM Iron Ore PB 2400 x D10 Capacity [t/h] Conveying speed, nominal [m/min] Installed power [kw] 2 x x x x x 200 The apron feeders are available in outboard design with the chains outside the area in between the skirt boards preventing chains and rollers from falling spillage material and inboard design providing shorter and lighter pans. For outboard designs, return rollers are mounted at the pans or mounted underneath the pans as for inboard chains. If mounted at the pans, the rollers move on a rail. Pans are heavy reinforced. As appropriate, greased slide rails are mounted in full length. Drive shafts are in one piece design. For large bearings, heavy plummer blocks are fabricated by TAKRAF in its own workshop. Chain tension is applied by screw type tensioning or with a tension frame (idler wheels mounted in it), hydraulically supported, mechanically secured. Chain force monitoring is available.
