Granulation powder for continuous dry pressing of flaky ceramic biscuit and preparation method of granulation powder
The invention relates to granulation powder for continuous dry pressing of a flaky ceramic biscuit and a preparation method of the granulation powder. The preparation method comprises the following steps: dissolving ceramic powder, a sintering aid, a dispersing agent and a binding agent, and carrying out ball milling and mixing to obtain ceramic slurry with the solid content of 50-55wt%; performing granulation on the ceramic slurry by using spray granulation equipment to obtain the granulated powder; the process parameters of the spray granulation equipment are as follows: the inlet temperature is 170-175 DEG C, preferably 172-175 DEG C; the outlet temperature is 70-74 DEG C, preferably 72-74 DEG C; the rotating speed of the atomizer is 7000 to 9000 rpm (revolutions per minute), preferably 8400 to 8800 rpm; the cyclone pressure difference ranges from 0.8 kPa to 1.2 kPa, and preferably ranges from 0.95 kPa to 1.05 kPa; the feeding speed ranges from 0.4 L/min to 0.6 L/min, and preferably ranges from 0.45 L/min to 0.55 L/min.
本发明涉及一种片状陶瓷素坯连续干压成型用造粒粉体及其制备方法。所述制备方法包括：将陶瓷粉体、烧结助剂、分散剂、粘结剂溶解并进行球磨混合，得到固含量为50～55wt%的陶瓷浆料；将所述陶瓷浆料利用喷雾造粒设备进行造粒，得到所述造粒粉体；所述喷雾造粒设备的工艺参数为：进口温度170～175℃，优选为172～175℃；出口温度70～74℃，优选为72～74℃；雾化器转速7000～9000 rpm，优选为8400～8800 rpm；旋风压差0.8～1.2 kPa，优选为0.95～1.05 kPa；进料速度0.4～0.6 L/min，优选为0.45～0.55 L/min。
