Coal feeder is the key mechanical equipment in the automatic loading system of coal preparation plant. Its main function is to control the quantity of coal according to the In traditional vertical coal bunker systems, a coal-feeder chamber (CFC) must bear the whole weight of the bunker. However, maintenance of CFCs within soft, Large-Deformation Failure Mechanism of Coal-Feeder

Abstract. Failure Modeand Effects Analysis (FMEA) technique is used to identify potential failure modes for a product or process before the problem occur, to initialization process, it is ready to start the coal feeder. If the coal feeder equipment is normal, start the coal feeder, if the equipment is abnormal, give an alarm and give a fault prompt. After the coal feeder starts and runs smoothly, the key parameters of the coal feeder are measured. If speed regulation is needed, the speed isImproved Coal Feeding Control System of Thermal

In traditional vertical coal bunker systems, a coal-feeder chamber (CFC) must bear the whole weight of the bunker. However, maintenance of CFCs within soft, swelling floor rock is a challenge faced in underground coal mines. Floor-heave control is a complex problem and is still not well-solved. Moreover, there is no report on the This paper introduces the mechanism-based fault diagnosis model of the main equipment of the milling system, and adopts the trend state detection and failure mode recognition methods according toCoal feeder fault control strategy Download Scientific

The invention provides a low voltage ride-through method for a coal feeder. The low voltage ride-through method for the coal feeder is characterized in that when the coal feeder normally operates, a main power source supplies power; when a low voltage breakdown of the main power source appears, the main power source is switched to a standby power COAL FEEDER UNTUK MEMINIMALISI SIX BIG LOSSES (Studi Kasus: PT.

Abstract The interaction of chambers leads to serious failure of surrounding rock, especially in complex stress environment of deep coal mines. In this paper, the mechanical model for single chamber under dynamic and static combined loading is constructed, and the instability criterion of surrounding rock is obtained. According to PURPOSE: A device for controlling a stoker is provided to apply flexible integrated logic through a program and to provide stable compatibility considering continuity with the menu of an existing stoker control device. CONSTITUTION: A device for controlling a stoker comprises a first motor(600), a second motor(800), a central controlling unit(100), an KR101119690B1 Coal feeder control system Google Patents
