JGC weighing full closed Coal Feeder

It is mainly coal equipment in thermal power Plant pulverizing system, in full closed state, it can not only uniformly, continuously coal, but furnace measurement and it is an ideal equipment which can achieve positive balance calculation coal consumption.

It is also used in continuous conveying and metering of bulk materials in other sectors of the field and realize the flow control of open- loop closed- loop and LAN management in factories according to users.


Closed pressure type cylindrical structure prevent effectively from dust spills and protect civilized production site.

The Observation window, Access door and Open-type cover distributed around the body which are convenient for your maintenance operations.

With self-bias, anti-bias structure, it can be made sure that normal conveyor and steady move.

Adopting our company high performance of electronic belt, it can make sure that the accuracy of measurement and long stability.

Weighing display instrument has optional RS232/485 communication interface.

Optional Frequency stepless operates smoothly, it ca not only energy saving, but satisfies requirements with open- loop site different flow closed loop regulation.

Chain scraper cleaning device can clean dust foreign objects inside the machine.

perfect alarm system can find and exclude failures of coal block, off coal,overload, Overtemperature and belt deviation,etc.


Work principle

1.the stoker uses tape drag raw coal operation, after raw coal is dragged by tape and in the tape drive, it moves forward steady by self-weight and friction between tapes, and thus realize continuous, uniform coal.
2.in the bottom of conveyor tape, stoker install weighing roller, weighing bridge, weighing sensor. Equipped with load cell weighing percussion is installed in conveying stringer machines. Weighing bridge supports weighing roller to check materials weight on the belt and produces an electrical signal proportional to belt load, sending to weighing display instrument.
3.Speed sensor connected to the drum, providing a series of pulse and each pulse represents a belt motor unit, and frequency pulses is positively proportional to the belt speed. The weighing display instrument receives two signals of weighing sensor and speed sensor, which displays the cumulative amount of transportation and instantaneous quantity of coal by enlarge, shaping, A / D conversion processing and integral calculation.
