Brief introduction for coal loading belt conveyor in some port China

Belt conveyors play an important role in the transportation of bulk materials in ports. There are two ways of loading and unloading transportation system : one is to unload coal from a truck then load it via a belt conveyor system; the other is to unload coal from a truck and It is stored in the yard by stacking conveyor, and then the coal is taken from the yard by the reclaimer and loaded by the belt conveyor.

There are three ways to unload coal trucks. The materials unloaded in the three ways are directly or reproduced through a main belt conveyor with a bandwidth of 1800mm and  capacity of 3600t / h. The coal is piled into the coal yard by a stacker with a rotation radius of 30m.

When loading the ship, coal is picked up by four bucket wheel reclaimers with a capacity of 3000t / h and a rotation radius of 45m. It is transported through two belt conveyors with a bandwidth of 2200mm with belt speed of 4.3m / s and capacity of 6000t / h. Ship loaders with a line capacity of 6000 t / h and a rotation radius of 33.5 to 49.5 m load coal into 100,000-ton or 25,000-ton coal hatches.

The entire system consists of 25 belt conveyors. The conveyors are equipped with metal detectors and iron removers. Electronic scale is used to measure the instantaneous and cumulative conveying amount of materials on the conveyor belt. The electronic scale at the discharge end can send out sampling signals.

The loading and unloading equipment is provided with a central control room, which uses centralized and automatic control to control and manage the entire system. The micro-controller is responsible for the control of the entire system. The console has manual control switches, automatic operation switches, on-site conversion operation switches, and the process is responsible for the entire system control. The console has manual control switches, automatic operation switches, on-site conversion operation switches, and process selection. Switches, various operation button indicator lights, alarm displays, etc. There are also synchronous display screens, industrial televisions, which can see the operation of the entire system loading and unloading equipment.

Controls include: process control, degree control, synchronous multi-process control, stop and emergency stop control, collision protection control of movable equipment; sample preparation device, metal detection device, measurement device, start of dust removal device, etc. Control room display.
