The milltype dryers are suitable in the cases in which the grinding and drying operations take place together. The mills vary significantly in terms of fundamental properties, shape, and operation depending on the fuel that is going to be dried. Therefore lignite milling differs fundamentally from milling bituminous and hard coals.

Lignite is a type of coal that is formed from the remains of ancient plants and is highly combustible. It is the lowest grade of coal and is typically left in the ground unless it is in an area that requires extraction. In recent years, the extraction and processing of lignite has become more popular due to its ability to generate more energy than other sources such as oil and gas.
