Pulverized coal bale breaker, storage and feeding measuring system
author：EBICO 2019-10-24
Work flow and principle: after being unpacked by the bale breaker, the ton bag pulverized coal becomes bulk coal and is stored temporarily. The temporarily stored bulk coal is conveyed to the pneumatic conveyor by the rated feeder. The mixed gas of air and coal is conveyed to the burner by the pneumatic conveyor and is burnt sufficiently under secondary air, certain temperature and pressure environment, so as to provide the drying drum with controllable heat continuously for heating materials.

Structure features:
(1) the whole system can be operated automatically by one operator with one button.
(2) Dust is removed by negative pressure induced air while unpacking; the conveying procedure is fully sealed; no floating dust will be generated during operation of the whole equipment.
(3) The level monitor of temporarily stored pulverized coal makes sure that the level of pulverized coal during work is always at the ideal and stable level.
(4) The pulverized coal temporary storage bin is equipped with a pneumatic arch-breaking device which ensures continuous and stable supply of pulverized coal.
(5) The rated supply of pulverized coal ensures the supply amount of fuel is under control; it works with the material temperature control system of the blender and controls the supply amount of fuel according to the requirements on material temperature, so as to ensure stable material temperature.
