A coal dryer for lignite should include explosion venting, a water deluge system and possibly an inert gas or a recirculated selfinerted process gas. Conversely, anthracite coal exhibits a high ignition temperature, rendering explosion vents or a deluge system in the coal dryer unnecessary.
Introduction to Lignite Dryer. Lignite dryer machine is a kind of rotary equipment for dewatering lignite coal. Lignite dryer is also called brown coal dryer and wood coal drying machine, which can realize continuous, industrial and automatic operation. It is designed specially targeted at lignite characteristics.
Lignite coal dryer is widely used for the drying of materials in cement mining building materials chemical food fertilizer production industry etc as a professional rotary kiln dryer manufacturer we are capable of offering kiln dryers which have the character of being easy to operate and durable in use.
offers 1,047 brown coal drying equipment products. About 0% of these are Spray Drying Equipment, 9% are Rotary Drying Equipment, and 13% are Drum Drying Equipment. A wide variety of brown coal drying equipment options are available to you, such as key selling points, local service location, and applicable industries.
Brown Coal Dryer Dryer Machine Lignite Drying Machine . And its output can reach tons hour online chat,Lignite rotary dryer accessories china ftm lignite rotary dryer price manufacturer fote lignite dryer is a professional largescale dryer to improve the quality of lignite, which can adjust the moisture of coking coal our company adopts advanced largescale fluidized bed dryer.
Wet coal slime/coal slurry/lignite are evenly sent to rotary drum dryer by feeding conveying system. After entrance into rotary dryer, wet materials will be led to oblique lifting area. Under the function of internal lifting plate, raw materials will fully exchange heat with hot air and evaporate partial moisture.

Fig 1 Drying curve for lignite coals. Drying of lignite coal is usually the first and essential step in most processes and technologies which are based on the use of such coal. However, there is no single universal method of drying of the lignite coal. There are very large number of patents of coal dryers and drying processes all over the world.

Lignite coal predrying technology Features of high temperature flue gas fluidized bed dryer Inlet flue gas temperature can be as high as 950C; Small equipment dimension, low capital investment and low energy consumption due to higher inlet flue gas temperature; Larger capacity: up to 500t/h water evaporation per unit; Coarse coal (up to 50mm) can be dried; Drying and deashing
Brown coal dryer Brown coal dryer. Brief Introduction of Brown coal dryer:. Zhengzhou TAIDA is the first study to dry brown coal drying professional equipment manufacturers, lignite is an important energy and chemical raw materials, but because of high moisture lignite (20% 40%), low calorific value (2700 kcal or so), spontaneous combustion etc. characteristics, resulting in lower selling
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed is considered the lowest rank of coal due to its relatively low heat has a carbon content around 25 to 35 percent. It is mined all around the world and is used almost exclusively as a fuel for steamelectric power generation.
Lignite dryer is known as lignite coal dryer, lignite drying machine, coal ash dryer, coal slag dryer and coal powder dryer because it can be used to dry materials like raw coal, coal slime or slurry, coking coal, coal ash, coal powder and coal slag. After being dried, the

Lignite is thus an important domestic energy resource. As a result of its capillary structure, lignite has a significantly higher water content than black coal, which generally has less than 10% water. The amount of physically and chemically bound water in the capillaries and
Lignite is the lowest rank of coal and has the lowest energy content. Lignite is crumbly and has high moisture content. Lignite accounted for about 8% of coal production in 2019. Subbituminous coal has a higher heating value than lignite. Subbituminous coal typically contains 35%45% carbon, compared with 25%35% for lignite.
