In order to meet the increasingly strict requirements for washing in the production process of ternary material precursors,multi-dimensional washing is a reliable engineering method for solving the high impurity content and large washing wastewater of precursors through the analysis of the washing method and mechanism of the developed multifunctional all-in-one machine.Through optimizing and combining the forward and reverse rotation,speed,lifting and lowering actions during the washing process,a multi-dimensional motion field is formed,which is organically integrated with the characteristics of the precursor to achieve a multi-dimensional washing.After the precursor is washed,the mass fraction of sodium(Na)is 0.015％,the mass fraction of sulfur(S)is 0.140％and the mass fraction of magnetic foreign matter is no more than 5.0x10-6％,which is better than the national standards and reduces wastewater discharge.
