DETAILS
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.
On plant start-up, the operator can select no.3 different operating cycles, as following described:
- Discharge on vessel’s bulk with shiploader SHP1 and conveyors BC1/BC2 working at 600 T/h each (total 1.200 T/h)
- Discharge on vessel’s bulk with shiploader SHP2 and conveyors BC1/BC2 working at 600 T/h each (total 1.200 T/h)
- Discharge on vessel’s bulk with shiploader SHP1 and SHP2, conveyors BC1/BC2 working at 1.200 T/h each (total 2.400 T/h)
- Otherwise the operator can select a “special cycle” and, depending on the line selected (i.e. working with a single or both shiploaders), manually input the corresponding speed of conveyors BC1-BC2 by means of inverters. Selection of the four (4) operating cycles above mentioned can be made by push button placed on the main operator panel.
