JGC-30型给煤机是一种称重式全封闭胶带给煤机，是火力发电制粉系统中的主要给煤设备。同时还可以用于其它工业锅炉行业连续供煤，它把原煤均匀（连续无级调整速度）地送八制粉球磨机、中速磨煤和尾扇磨煤中，并可实现单炉计量。

　　该给煤机在封闭箱中利用皮带传动进行原煤输送、系统布置灵活，结构简单、安装方便、系统中设置计量装置可实现变速称重，调速范围广，维修量小、运转平稳、寿命长、节能降耗输送量大、电机功率小、效率高。

　　本机装有能与高温分离的闸门，为安全维修提供方便。本设备在给煤机头部、尾部及中部计晕段部位装有观察口，内装有照明装置，便于随时观察机器运行情况，底部设置有漏煤清扫保险装置，如遇故障能自动停止清扫系统运行。

　　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
