Application and Typical Trait of Lignite Coal Dryer

Lignite coal dryer is usually used in the chemical, building and mineral processing industry. Its specific applicable fields and usage are the following ones:

1. The coal industry, coal, coal slurry flotation plant, mixing plant material such as drying;

2. Building industry blast furnace slag, clay, pang betonies, limestone, sand, quartz material such as drying;

3. Mineral processing industry of various kinds of metal ore concentrate, slag, tailings material such as drying;

4. Chemical industry with not dry and heat-sensitive materials.

The main features of lignite coal dryer in the industrial process:

1. Dryer use downstream dry way, flue gas and wet material from the same side into the drying machine, can use high temperature flue gas get high evaporation intensity, drying machine outlet temperature is low, high thermal efficiency, fuel consumption, dry low cost, resistance to overload ability, large in capacity;

2. New type of feed and discharge device, to eliminate the drum drying machine feeding jams, discontinuous, uneven phenomenon such as return product and reduce the dust removal system load, according to different material property change operation parameters, make the material in the dryer cylinder body form stable all broken fabric curtain, quality heat exchange more fully.

3. New internal structure, strengthen the already scattered material cleaning and heat conduction function, eliminates the cylinder body of wall with sticky phenomenon, to material moisture, viscous adaptability stronger.

4. Dryer use 'self-aligning type jockey pulley device', make supporting roller and roller ring with a linear contact forever, which greatly reduces the wear and power loss, dryer to achieve the 'zero level thrust', greatly reducing the stop supporting roller wear, barrel stable running and reliable.

Besides, it can control product size and water content according to customer request.
