More Information
Summary:The invention relates to a method for removing water from a particulate material selected from the (oxy) hydroxides and carbonates comprising at least one nickel or cobalt and at least one metal other than nickel, the process comprises the steps of introducing at least one particulate material having a moisture content of 1-30 wt.% relative to the particulate material into a rotary kiln having external heating elements and moving it through the rotary kiln together with a gas stream wherein the residual moisture of the resulting product is 50 ppm to 1.5 wt.%. 本发明涉及从选自包含至少一种镍或钴和至少一种除镍以外的金属的(氧)氢氧化物和碳酸盐的颗粒材料中除去水的方法，所述方法包括将至少一种相对于所述颗粒材料具有1-30重量％的含水量的颗粒材料引入具有外部加热元件的回转窑中，并使其与气流一起移动通过回转窑的步骤，其中所得产物的残余水分为50ppm至1.5重量％。
