JGC-30型給煤機是一種稱重式全封閉膠帶給煤機，是火力發電制粉系統中的主要給煤設備。同時還可以用于其它工業鍋爐行業連續供煤，它把原煤均勻（連續無級調整速度）地送八制粉球磨機、中速磨煤和尾扇磨煤中，并可實現單爐計量。

　　該給煤機在封閉箱中利用皮帶傳動進行原煤輸送、系統布置靈活，結構簡單、安裝方便、系統中設置計量裝置可實現變速稱重，調速范圍廣，維修量小、運轉平穩、壽命長、節能降耗輸送量大、電機功率小、效率高。

　　本機裝有能與高溫分離的閘門，為安全維修提供方便。本設備在給煤機頭部、尾部及中部計暈段部位裝有觀察口，內裝有照明裝置，便于隨時觀察機器運行情況，底部設置有漏煤清掃保險裝置，如遇故障能自動停止清掃系統運行。

　　Model JGC-30 Full-Sealed Coal Weighing Feeder Is a kind of  belt weighing feeding coal device, and it is the main coal feeding device in the milling system of the power plantand also it can be used for continous feeding coal for other boiler appliction, it may equally feeding the coal into the ball crusher.medium speed crusher and tail crusher. and it could achleve single boiler weighing The coal feeder use the belt driven in the closed-box to achieve the raw coal transport A flexible system layout.simple structure. easy to install Owing to being set up the measuring device in this system. it can achieve the various speed weighing. and it has a large adjustment speed range, low maintainence. smooth operation.good stability. lower power. larger transportation capacity.high efficiency This machine is equipped with high-temperature separation of the gate, in order to fadhtate the maintenance of securlty Of this equipment in the coal feeder in the head. tail section and central parts of measurement I have observed. there are builtin lighting fixtures, at any time convenient to observe the machine running,The coal cleaning device is also set up at the bottom of the system. it may be stop the automatic cleaning system in the case of failure
