TFY multifunctional centricleaner can control the density of coarse slag by axial washing water, which can control the loss of fiber effectively. With less fiber loss, the required number of centricleaners and stages are reduced correspondingly. The separation efficiency is higher, and the operation density is up to 2%. The ceramic cone is made under isostatic press, and the outer wall is processed by CNC lathe, the size accuracy is high, and the inner surface is very smooth. The reject content in the coarse pulp is high and the fiber loss is smaller. Through the dilution of the coarse and continuous pulp removal in all sections, the blocking phenomenon will not occur during the operation. The main features are reducing fiber loss, improving capacity and reducing the number of stages and centricleaner.
