2836 – SELFUNLOADING SYSTEM FOR TRANSHIPPER “BULK BORNEO”
SOLUTION FOR BULK MATERIAL, EXTRACTORS, HOPPERS, SHIP LOADERS, BELT CONVEYORS
The plant concerns a transhipment system to be installed on new geared pontoon “Bulk Borneo” (the transhipper) for coal transport, capacity 2000t/h, capable of loading Cape Size from 180,000 DWT to 9 holds and Panamax from 80,000 DWT to 7 holds, through the two grab cranes which feeds the receiving hoppers TR1/TR2 and from each hopper the handled material is extracted by means of two belt conveyors BC1/BC2 and conveyed into a single belt conveyor BC3 placed transversely extractors
On the discharging section of conveyor BC3 a flow-regulating by-pass is provided to discharge the material on two belt conveyors BC4/BC5, each of which feeds a shiploader (SHP1 e SHP2). The air draft of the shiploaders from sea level is abt. 18,5m. When operating to load Panamax and Capesize vessels, the plant operates with two shiploader having span between supporting column and chute axis of abt. 30m, and the material flow can be divided on both shiploaders SHP1 and SHP2.
On belt conveyor BC3 a belt scale is provided for the monitoring of material flow. On both conveyors BC1 and BC2 a metal detector is provided to detect unexpected metal parts. When detecting a ferrous part or component, metal detectors control unit generate a signal which will stop the line. A sampling system is provided on belt conveyor BC3.
The plant can operate in the following modes: Manual mode, for plant maintenance and start-up tuning. In this case the plant is fully under control of the operator, whom have the responsibility and can operate the plant both from control cabin and locally by means of a remote control. Semi-automatic mode. The single machines run in automatic mode under PLC supervision, start and stop are manually commanded from main operator panel, boom luffing and rotation of shiploaders by means of a remote control (under PLC supervision). Selection of operating modes no.1 and no.2 is made by manual selector installed on the main operator panel.
