Coal slime dryer FUYU manufacture

Coal slime dryer

1. Product introduction:

Coal slime dryer adopts unique scattering device, the bond of slime scattered after drying, increased the contact area of the coal slime with hot air and the heat utilization efficiency can be greatly improved, after drying the slurry can be disposable water cut to below 12%, after drying the slurry can be directly used for fuel. The reuse of slime. Also the R & D Department of my company after years of unremitting efforts, the boiler exhaust gas as the slime dryer heating source, the successful launch of the boiler waste gas drying machine. To make heating without investment, with heat without cost. Real energy saving and drying, truly energy-saving environmental protection.

2. Product usage：

Efficient energy-saving coal slime drying machine is in drum dryer based on the development of new drying equipment can be widely used in:

1. Of the coal industry, coal, coal, coal slime flotation clean coal mixed materials drying.

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

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

4. Chemical industry nondrying of thermal sensitive material.

3. Working principle:

The slime itself has high humidity, high adhesion, in the drying process of wet coal slime scattered into the equipment through the conveyor belt, the following work area after massive slime scattered into a fast vacuum dryer: one is the feeding area, wet coal into the area and high negative pressure hot air after being contacted evaporate rapidly a lot of water, slime in the lead angle of the copy board copy move, Form not bonding under the guidance of a work area; the two is to clear the area, this area is wet coal slurry copy board took form the material screen state, material falls to form a bond of the drum wall phenomenon in this area due to equipment design a cleaning device, coal cleaning device can quickly clean out the bonding cylinder wall. In this process, cleaning device for material, pellet agglomerate is broken, thereby increasing the heat exchange area, improve the heat transfer qualitative efficiency, improve drying rate; the third is inclined Yang plate area, this area is low temperature drying area, slime in this area has a low moisture loose state, this area has no binding phenomenon, after the heat exchange finished products meet the required moisture requirements as the campaign entered the final discharge area; the fourth is the material of the drying host drum in this area is not provided with a copy board, material in this area rolling sliding to the discharging mouth, complete the whole drying process。
