PROCESS FOR SIFTING A MIXTURE OF A MILLED MATERIAL AND A FLUID, AND MILL SIFTER

摘要

The invention relates to a method for sifting a mixture of milled material and a fluid and to a mill sifter, in particular for carrying out the process according to the invention. To improve the milling-sifting process and the subsequent dust separation and, in particular, to optimize the energy balance of a milling installation, it is envisaged according to the invention not only to reduce or eliminate the swirling of the stream of fine material and fluid emerging with an angular momentum from the dynamic part of the sifter but also to make it more uniform and deflect it into a virtually linear flow with the aid of a distributor and a displacer in a sifter outlet housing. The fixed distributor, arranged coaxially in relation to the axis of the sifter in the sifter outlet housing, and the displacer may be formed as one unit and the directing elements of the distributor may be arranged on the displacer, reaching almost as far as the inner wall of the sifter outlet housing.
