Abstract
A rotary disintegration apparatus comprises a housing with a central material input and a material outlet that is open underneath, an inner rotor fixed to a first shaft and an outer rotor fixed to a second shaft on the same axis that rotates in the opposite direction, and blade rings that follow each other in alternation having blades which are inclined in the direction of rotation, which can be coated with a protective layer, which have front and rear edges of hard wear-resistant material, and which sit on one side on retaining rings and on the other side on assembly rings forming replaceable components of annular assembly ring carriers that are connected to the shafts. The blades are so arranged at a distance from the edges of the assembly and retaining rings of their blade rings that the front edges of the blades of a blade ring and the rear edges of the blades of the following blade ring which rotates in the opposite direction define annular chambers within the disintegration chamber, within which, within the nominal speed range of the rotors, vortex zones of the gas-solids mixture are formed.
