A drier for bulk materials in which heat generator is placed in the lower part of the drier, and in the drying chamber on vertical axles active executive devices are installed, those are formed with profile curled in the form of cylindrical screw line, the active executive devices are installed in such a way that the inter-axial distance between two neighboring active executive devices is smaller compared to diameter of the active executive device. The turns of screw lines of all the active executive devices are unidirectional, and active executive devices are installed with possibility of rotation with respect to the axis with same angular velocities in direction that provides lift of the turns of the screw line. |
