3N-CF Fully-Airproof Coal feerder is exploited on the base of Scale. It meets the some special needs of weighing and controlling and Positive suppress coal feeding into dynamotor boilers in power plant and boiler in steel plant.
This equipment is suit for varies of boiler coal feeding system. It has such advantage as simply structure, easy maintain and feeding continuum and equality and reliable. In whole running process, not only weighing precisely and also give a lot of information such as flow, accumulative total and control and also adjust coal federate according real feeding situations.
