The invention provides a ceramic material suspension granulation device, including a feeding device and a granulation suspension tower. The upper part of the pelletizing tower is a cylinder, the lower part is a cone structure, and the air guide groove is located at the junction of the cylinder of the pelletizing tower and the cone, along the circular cylinder along the circular cylinder, and the pressure produced by the external high pressure levitation fan. Force wind, through the guide trough to produce upward suspension force, under the action of suspension force, micro particles constantly reunite and adsorb, gradually increase the ball into particles, forming particle powder, when the weight of the particles is greater than the air suspension force, the particle powder that reaches the process requirements outflows from the outlet. The preparation of powder by the invention can overcome the shortage of high energy consumption and high cost of powder preparation by wet powder technology. It also solves the technical problems of unreasonable distribution of powder particles, poor fluidity and too large bulk density of the powder material prepared by the existing dry process technology.

一种陶瓷原料悬浮造粒设备
本专利技术涉及一种陶瓷原料悬浮造粒设备,属于陶瓷行业原料处理设备领域。
技术介绍
目前陶瓷行业进行粉料颗粒制备时,一种是湿法制粉工艺,即先将原料配方料入球磨机加水32~35%细磨成泥浆,将制好的泥浆用泵打入喷雾干燥器,用热风将泥浆烘干到6~8%水分,制成压型颗粒粉料,该粉料粒度分布在18~100目筛的范围,该范围内的颗粒含量达到90%,容重大约0.90g/cm3,所造粉料颗粒规则,流动性好、容重合适,便于后续的压型需要,其缺点是:由于要蒸发大量的水分,需要消耗大量的热量,能耗很高。一种是干法制粉工艺,将原料配方料入干法粉磨机,干法研磨到小于0.063mm(250目筛或更细)的粒度,在经过成球造粒装置制备成粉料,采用的造粒装置有轮碾机,盘式造粒机,挤压式造粒机,辊筒式造粒机。其成球造粒过程为向成球造粒机中加料加水,利用滚压、挤压、强力搅拌的不同原理和方式,进行成球造粒制粉。该过程的加水量为10~12%,然后通过其它干燥方式干燥粉料到6~8%水分,供生产使用。经过干法制备的粉料,颗粒分布不合理,在18~100目筛的范围内分布的颗粒百分含量大约 ...
