Method for recycling zirconia ceramic waste
The invention discloses a method for recycling zirconia ceramic waste. The method comprises the following steps: cleaning the zirconia ceramic waste; crushing the cleaned zirconia ceramic waste by using a double-roller machine to obtain a crushed material; crushing the crushed material by using a jet mill to obtain a crushed material; mixing the crushed material with water to obtain mixed slurry with the solid content of 15-30%, grinding the mixed slurry by using a grinding machine, conducting standing after grinding, and separating clear liquid to obtain slurry with the solid content of 30-45%; carrying out spray drying on the slurry to obtain zirconia ceramic recovery powder; and pressing and sintering the zirconium oxide ceramic recovery powder to obtain a regenerated zirconium oxide ceramic device. According to the method, the zirconium oxide ceramic waste is recycled through a pure physical method, the recycled powder with uniform particle size distribution is obtained, the zirconium oxide ceramic device with excellent performance is prepared through pressing and sintering molding, the recycling process is low in energy consumption, low in cost, short in technological process, easy to implement and high in efficiency, and regeneration and recycling of zirconium oxide are achieved.
本发明公开了一种氧化锆陶瓷废料再生利用的方法，包括：对氧化锆陶瓷废料进行清洗；用对辊机将清洗后的氧化锆陶瓷废料进行破碎，得到破碎料；用气流粉碎机对破碎料进行粉碎，得到粉碎料；将粉碎料与水混合，得到固含量为15％～30％的混浆，用研磨机对混浆进行研磨，研磨完成后静置，分离清液，得到固含量为30％～45％的浆料；对浆料进行喷雾干燥，得到氧化锆陶瓷回收粉；对氧化锆陶瓷回收粉进行压制，烧结成型，得到再生的氧化锆陶瓷器件。本发明通过纯物理法对氧化锆陶瓷废料进行回收，得到粒度分布均匀的回收粉，并通过压制和烧结成型制备成性能优异的氧化锆陶瓷器件，回收过程能耗小，成本低，工艺流程短，容易实施，效率高，实现了氧化锆的再生循环利用。
