Slag drier

详情

Slag dryer is mainly used for drying iron ore, titanium, quartz sand and other material, which has certain humidity or granularity. Especially in the drying slag, mine dryer has the advantages of large capacity, wide range of application, less flow resistance, larger fluctuation range during work and easy operation. 

Slag dryer main applicable area:

1. The coal industry coal, coal with flotation, drying mixed coal and other materials drying;2, the construction industry blast furnace slag, clay, limestone, sand, quartz and other materials drying;3, processing industry, metal concentrates, slag, tailings and other materials drying;

Working principle 

Slag was transported to the hopper by the belt conveyor or bucket elevator, and then enter into the feed end through the feeding tube by the hopper feeder. Slope of the feeding pipe must be greater than the natural inclination of material so that the materials can flow into the mine dryer. Dryer cylinder forms a slightly tilted with the horizontal. Material was added from the higher to form reflux with the heat carrier entered from low-end. Sometimes, heat carrier flows into the cylinder together with the material. With the rotating of drum, material run to the lower end by gravity. In the moving process, wet materials obtain the heat of heat carrier directly and indirectly to be dried, then, the finished materials are sent out by belt conveyor or screw conveyor.

The wall plate of cylinder body can lifting the materials up and down, increasing the contact area of material and air flow to improve the drying rate and promote the progression of materials, the heat carrier is generally classified into the hot air flue, gas flue, etc. dust cyclone need to capture down the materials carried by gas, if the dust content of off gas needs to be reduced in further, bag filter or wet dust also should be used.
