Coal drying machine of lignite coal dryer manufacturer in China
Lignite coal dryer, also known as lignite dryer, is a drying machine mainly used for drying lignite coal.
Working principle of lignite coal dryer:
Lignite coal are sent to hopper of rotary dryer by belt conveyor or bucket elevator. The barrel is installed with slope to horizontal line. Materials enter the barrel from the higher side, and hot air enters the barrel from the lower side, materials and hot air mix together. Materials go to the lower side by gravity when the barrel rotates. Lifters on the inner side of barrel lift materials up and down to make materials and hot air mix completely. So drying efficiency is improved.
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.
