Allgaier TTM combined drums are available both in single-shell and double-shell versions. This special drum design is a combined system in which bulk materials are dried and comminuted or deagglomerated in a single unit, making it possible to use only one mount and one drive system.
After being fed into the drum, the coarse, lumpy wet material is first pre-dried and then comminuted or deagglomerated in the grinding track consisting of the outer cylindrical shell and the rolling grinding elements inside of it. During this process, the moisture inside of clumps and filter cakes is exposed so that it can be dried. After this zone, the comminuted bulk material is dried further until it reaches the desired residual moisture content level.
Ideal for: Filter cakes, ceramic raw materials, and pre-dewatered sludges
