Granulation method of recycled ceramic oxide powder
The invention relates to a granulation method of recycled ceramic oxide powder. The granulation method comprises the following steps: (1) mixing the recycled ceramic oxide powder with pure water, adding the obtained mixture into a ball mill, and then adding a dispersing agent and a defoaming agent; (2) carrying out stirring and ball-milling, then adding a binder, and continuing stirring to obtainslurry; (3) carrying out centrifugal spray drying on the slurry, and then carrying out degreasing and sintering to obtain sintered recycled powder; and (4) screening the sintered recycled powder to obtain the recycled ceramic oxide powder meeting requirements on raw powder. According to the method, undeposited recycled ceramic oxide powder generated in plasma spraying or other thermal spraying processes is recycled and granulated again, so the requirements of the plasma spraying process on particle size distribution, particle morphology, purity, components and the like of composite ceramic oxide powder are met again; and ceramic oxide powder resources are efficiently utilized, and the raw material cost of the plasma spraying process or other thermal spraying processes is effectively reduced.
本发明涉及一种陶瓷氧化物回收粉的造粒方法，所述方法包括以下步骤：(1)将陶瓷氧化物回收粉与纯水混合，加入球磨机中，然后加入分散剂、消泡剂；(2)搅拌球磨，然后加入粘结剂继续搅拌，得到浆料；(3)将浆料进行离心喷雾干燥，然后脱脂烧结，得到烧结后的回收粉；(4)将烧结后的回收粉进行筛分，得到符合原料粉要求的陶瓷氧化物回收粉。本发明将等离子喷涂或其他热喷涂工艺中产生的未沉积陶瓷氧化物回收粉重新回收、造粒，使其再次满足等离子喷涂工艺对复合陶瓷氧化物粉粒度分布、颗粒形貌、纯度、组分等的要求；使陶瓷氧化物粉体资源得到高效利用，有效降低等离子喷涂工艺或其他热喷涂工艺的原料成本。
