Overview

General Introduction:

Lignite dryer is also called brown coal dryer machine or lignitic coal drying machine. Lignite dryer adopts the new technology of crushing lignite first and thermal drying. It makes the drying process achieve continuous, industrialization and automation. After being dried, the water content of the lignite brown coal drops from 25%~30% to less than 13%.

Fote Machinery is a famous lignite dryer manufacturer. The products all have cheap price and great quality. You can get in touch with us to get more detailed information. We will always at your service.

Structure:

Lignite dryer's main components are: crushers, conveyors, feeders, heat source equipment, Rotary dryers, feeders, air systems, dust control equipment, electrical systems and other, temperature control device and so on.

Applied Fields:

1. The coal industry, coal, coal slime flotation, mixing materials

2. Blast-furnace slag in construction industry, clay, clay, limestone, sand, quartz and other materials dry;

3. Processing industry of metal concentrate tailings, waste;

4. Non-heat-sensitive materials in the chemical industry is dry

Features

Lignite dryer

1. High overload resistance, large capacity, low fuel consumption, low cost of drying;

2. Adopt downstream drying flue gas enters the dryer with the wet material from the sameside. You can take advantage of high temperature flue gas evaporation, low temperature of dryer outlet, high thermal efficiency;

3. According to the different material properties to change operating parameters make the item in the dryer cylinder capable of forming stable full-face cascade, mass and heat exchange more fully;

4. New feeding and discharge devices, put an end to the dryer drum feed inhomogeneous congestion, discontinuous, and phenomena such as returns, reduces the dust load of the system;

5. The new internal structure, intensify cleaning of disperse materials and thermal conduction, eliminates the adhesion phenomenon of the cylinder wall, material moisture, stickiness of more flexibility;

6. Lignite dryer achieves a 'zero lift', greatly reducing wear retaining rollers, cylinder stable, reliable operation;

7. Lignite dryer adopts 'aligning roller device' so that wheel and tyre fit is a linear exposure, thereby greatly reducing wear and power loss;

8. According to user requirements of granularity and moisture, drying coal mud water up to less than 8% and the following granularity can be controlled in 8mm.
