摘要

Method for operating grinding continuous dry an attritor tower, quepresenta - a container vertical milling, closed (1), - a conveyor worm (2) arranged centered container grinding ( 1) with - a drive shaft (4) with a central axis (3) and - at least one flat surface between turns (5) placed on the drive shaft (4), that WILL extends a height (hs) to an upper end (6) covering the delcontenedor cross section of grinding (1) only partially, - a package of grinding bodies (17) with an upper surface (39), - input material to be ground (19) flows over the package grinding bodies (17) in the container mill (1), - a gas inlet (24, 24 ', 24 ") leading into the container mill (1) for alimentaciónde gas, - output ground material (11) discharged from the grinding container (1), having a lower edge (18) and a height (h 13) for discharge of ground material (22) and gas and - a motor (7) for driving the conveyor worm (2) in a direction of rotation (8) , whichthe at least one flat surface between turns (5) carries grinding bodies (17) upward, characterized in - that the surface (39) of the package grinding bodies (17) in the rotary drive deltransportador worm (2 ) is set approximately frustoconical so quecae radially outwardly so that ends radially outside in the area of ​​the lower edge (18) dela output ground material (11), - that the gas is introduced above the parcel of grinding bodies (17) in the demolienda container (1) and - gas and ground material (22) is discharged in the area of ​​the surface (39) of the package cuerposmoledores (17) through the output ground material ( 11) from the grinding container (1).
