The Description of Mining drying machine

The mining roasting machine is a kind of high-efficiency ,energy-saving drying  machine manufactured by our company after many years study ,on the basis of the sucessful experience of the similar products at home and abroad .Among a wide rang of these drying  machine ,this one is one of our flagship product.

we are on the leading side both in design and manufacture of roasting equipment .It is mainly used to dry the the mineral materials ,such as iron ore ,quartz ore etc.Furthermore ,the rotary dryer have well adaptability,generally applied to granular and massive ore ,and can also roast the cream materals with comparative high humidity and the mineral wast residue .

The Miing dryer is of many advangtages of large capacity ,high flexibility, operational convenience and so on .

The Working principle of Mining drying machine

1.The mineral waste residue are conveyed to silo by belt conveyor or bucket elevator ,and transport to the feed end by the feeder of silo .(The inclination of the feeding pipeline should be exceed the natural inclination of materials ,so that to facilite ore to flow into drier smoothly) .The rotating cylinder of the machine is slighly inclined to the horizon .

2.To feed the material from the higher end and the heat carrier enter from the lower end ,such produce adverse contactbetween them .sometimes,they can be fed to the cylinder together .As the cylinder running,ores carried to the lower side by the gravity.

3.In the process of moving fruward ,the wet raw material being roasted by the heat directly or indirectly .

4.The finished items turn out via belt conveyor or spiral conveyor.

There is shoveling plate installed in the tank with function of shoveling the materials up and down,to enlarge the contact area between airflow and materials and to enhance the efficiency .

After drying  ,It need cyclone dust collector to catch the items in the airflow.in addition ,we should use bag tyoe or wet-type dust collector and afterward discharge the waste gas,if you intend to further reduce the dust load of the exhaust .

The mining roasting machine adopted new combined device system on the basis of technological inonovation ,and conquered the shortcomings of the traditional one .therefore thermal efficiency is lifted ,consequently ,the comsuption of coal decreased by 20%.It can be applied to various combustion furnace,for instance ,high-temperature fluidezed furnace ,grinding coal powder spraying furnace and mannual operated furnace .The traditional cast still gear is replaced by the pin colume changeable one,which would economize the cost investment ,greatly decrease the expense and time in maintenance.
