    摘要： The present invention relates to a round and spherical titanium dioxide scouring media and a method for producing the media. The scouring media is effective in removing titanium dioxide buildup on the walls of a titanium dioxide reaction vessel. The method consists of forming green titanium dioxide pellets in a high intensity mixer by mixing commercially available titanium dioxide dust and water. The high intensity mixer produces substantially round and spherical green pellets which are subsequently sized and sintered in a kiln to form round and spherical titanium dioxide sintered pellets that are suitable as a scouring media. The high intensity mixer allows the operator to closely control the size and shape of the pellets during the forming process to produce substantially round and spherical green pellets. Because the sintered titanium dioxide pellets are substantially round and spherical in shape, they are much less abrasive to the walls of the reaction vessel. Furthermore, as the pellets themselves abrade away, they do not contaminate the titanium dioxide product, and they can even be reprocessed into round and spherical scouring media.

    摘要翻译： 本发明涉及圆形和球形二氧化钛冲洗介质及其制备方法。 精练介质有效地在二氧化钛反应容器的壁上除去二氧化钛。 该方法包括通过混合市售的二氧化钛粉尘和水在高强度混合器中形成绿色二氧化钛颗粒。 高强度混合机产生基本上圆形和球形的生球团矿，其随后在窑炉中定尺寸和烧结，以形成适合作为冲刷介质的圆形和球形二氧化钛烧结颗粒。 高强度混合器允许操作者在成型过程中紧密地控制颗粒的尺寸和形状，以生产基本圆形和球形的绿色颗粒。 因为烧结的二氧化钛颗粒的形状基本上是圆形和球形的，所以它们对反应容器壁的磨损要小得多。 此外，当颗粒本身磨损时，它们不会污染二氧化钛产品，并且它们甚至可以再加工成圆形和球形冲洗介质。
