Pressure-Rsistant Gravimtrie Coal Feeder GM-BSC22

The coal-fueled thermal power generation will go hand in hand.. with preservation of the nature. Thanks to the technological advances in suppressing emission of gases harmful to the environment, such as NOx, SOx, and CO2, coal has come back into the spotlight as an alternative energy source in thermal power generating facilities around the world. It is said that by the year 2010, the coal-fueled thermal power generation will have contributed by more than half the total energy generated in the world. In addition to electric utilities companies, an increasing number of corporations---- especially...

Pressure-RsistantGravimtrieCoalFeeder GM-BSC22 This is a continuous weighing machine used to weigh and feed specified amount of coal from the coal storage tank directly into the pressurized mill. 1.Dust-proof, explosion-proof load cell A dust-prooft explosion-proof load cell is incorporated as the weighing sensor. 3.A specially designed conveyor belt & clean-out conveyor The conveyor belt is equipped with corrugated lugs (60 mm H) to prevent coal from spilling over the sides of the belt. The design and matehals used in the conveyor belt leave no gaps. The clean-out conveyor underneath collects...

Advantages Load cell The dust-proof, explosion-proof load cell yields a linearity of +/- 0.05%. The load cell supports the weighing carrier rollers directly, retaining highly accurate weight readings. The conveyor belt The conveyor belt is equipped with corrugated lugs which spread when the belt passes over rollers, to prevent coal from spilling over the sides of the belt. Rubber lagging covered head The head roller is covered with rubber lagging, which helps prevent the accumulation of coal on the surface of the roller, and keeps conveyor belt from skidding sideways. External belt cleaner This...

ANDFUNCTIONSOFTHESYSTEM Principleofopration The coal in the coal bunker is fed on the conveyor belt (weigh-ing belt) inside the pressure-rsistant chamber through the coal g驢te and the downspout The chamber inlet chute is cylindncally-shaped to maximize loading efMciency. The load cell installed beneath the conveyor belt measures the amount of coal discharged from the conveyor belt into the mill as a load factor (kg/m) when rt passes over the weighing section. The befl speed (m/min.) is detected by the puise genera-tor attached to the driving unit. Thͨse two signais are multiplied in the control...

We custom-make specially-designed coal feeders if a special inlet mouth size or a special pitch is required between the inlet and outlet mouths. Coal sampling device This device is used to sample the coal inside the chamber. Automatic and manual types are available. Coal gate It is positioned between the coal bunker and the downspout of the coal feeder, to stop the coal flow when you need to perform service, maintenance, etc. Automatic and manual types are available. Miscellaneous ¥Downspout ¥Coal flow monitor ¥Dresser coupling ¥Explosion-proof electric parts ¥Coal chute We also custom-make coal...

THENEEDSARISE We remain ready to meet diverse requirements by manufacturing the following two models which were developed in the 1980s. GM-BSC11 The GM-BSC11 was first developed in 1980. This model was designed to allow the entire weighing conveyor to be removed easily from the chamber, for simplified maintenance. GM-BSC21 This model was designed to allow the weighing belt, the head & tail rollers, and the carrier rollers to be removed Ihrough the Windows built in both sides of the chamber, allowing easier maintenance in a limrted ftoor space. The current model. the GM-BSC22, was based on this...
