With the rapid development of the economy, China's coal development is gradually realizing the automation of machinery, and the amount of coal and pulverized coal directly produced is also increasing year by year. The final product of the coal production line is also a by-product of coal slime. In the past, the place where the slime was produced was generally nothing more than piled up or sold at low prices to ordinary people.

Slime is characterized by fine grain size, high moisture content, high ash content, and high clay content. Due to many shortcomings, the use of slime has caused great inconvenience. The powerful drying capacity of the slime dryer enables the slime to achieve its due value. At present, the world's coal resources are very scarce, so the use of slime has become more and more important.

The professional equipment adopts the method of drying and crushing coal slime, and has good control over the moisture and composition of the slime. The slime that has not been viewed by people has also achieved economic value. To extend the service life for the shortage of coal resources. This shows that the development prospects of the slime dryer are very broad.
