Coal drying equipment of coal sludge dryer for drying coal slime

coal sludge dryer, also known as lignite coal dryer, coal slime dryer, coal slurry dryer, is a kind of drying machine mainly used for drying  coal. 

coal sludge dryerstructure:

coal sludge dryer is formed by rotary body, lifting blade, driving device, supporting device and bigger gear, smaller gear, motor and reducer.

Working principle of coal sludge dryer:

On the condition of maintaining the quality of the lignite coal, lignite rotary dryer adopts low-temperature four-level drying technology to evaporate the water containing in the lignite coal to below 13%. The first-level drying area removes most water at the high temperature sate with 400℃ of high temperature, making sure that the chemical component of the lignite coal remains the same and that the lignite coal is not easy to burn; the second-level drying area has the indoor temperature of 300℃, it will remove the water through medium-temperature strong induced air to make sure that the lignite coal do not have coking; the third-level drying area has the indoor temperature of 120℃-210℃, and the crushing device inside the roller will repeatedly hit and scatter the materials and dry them with fair current; the fourth-level drying area is high exhaust area, and the indoor temperature is 60℃-80℃, and the water containing in the materials will be removed by the low-temperature hot airflow with negative pressure of the induced air system.

coal sludge dryer application:

coal sludge dryer can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste, and clay stone. They are widely used in building materials, metallurgy, and chemical industry.
