High Efficiency Hot Coal Slime Dryer

Coalslime dryer

1. 1.     Productintroduction:

Coalslime dryer adopts unique scattering device, the bond of slime scattered afterdrying, increased the contact area of the coal slime with hot air and the heatutilization efficiency can be greatly improved, after drying the slurry can bedisposable water cut to below 12%, after drying the slurry can be directly usedfor fuel. The reuse of slime. Also the R & D Department of my company afteryears of unremitting efforts, the boiler exhaust gas as the slime dryer heatingsource, the successful launch of the boiler waste gas drying machine. To makeheating without investment, with heat without cost. Real energy saving anddrying, truly energy-saving environmental protection.

1. 2.     Productusage：

Efficientenergy-saving coal slime drying machine is in drum dryer based on the developmentof new drying equipment can be widely used in:

1. Ofthe coal industry, coal, coal, coal slime flotation clean coal mixed materialsdrying.

2.The construction industry blast furnace slag, clay, limestone, sand, quartzstone and other material drying.

3.Mineral processing industry of various metal concentrate, waste, tailings andother materials of dry.

4.Chemical industry nondrying of thermal sensitive material.

1. 3.     Workingprinciple:

Theslime itself has high humidity, high adhesion, in the drying process of wetcoal slime scattered into the equipment through the conveyor belt, thefollowing work area after massive slime scattered into a fast vacuum dryer: oneis the feeding area, wet coal into the area and high negative pressure hot airafter being contacted evaporate rapidly a lot of water, slime in the lead angleof the copy board copy move, Form not bonding under the guidance of a workarea; the two is to clear the area, this area is wet coal slurry copy boardtook form the material screen state, material falls to form a bond of the drumwall phenomenon in this area due to equipment design a cleaning device, coalcleaning device can quickly clean out the bonding cylinder wall. In thisprocess, cleaning device for material, pellet agglomerate is broken, therebyincreasing the heat exchange area, improve the heat transfer qualitativeefficiency, improve drying rate; the third is inclined Yang plate area, thisarea is low temperature drying area, slime in this area has a low moistureloose state, this area has no binding phenomenon, after the heat exchangefinished products meet the required moisture requirements as the campaignentered the final discharge area; the fourth is the material of the drying hostdrum in this area is not provided with a copy board, material in this arearolling sliding to the discharging mouth, complete the whole drying process。
