Ceramic powder preparation process and system
The invention relates to the technical field of ceramic wet powder preparation, in particular to a ceramic powder preparation process and system. The ceramic powder preparation process comprises the following steps: S1, drying mud to obtain mud blocks with the water content of 12%-14%; s2, rubbing the mud blocks with more than two screens which are sequentially arranged layer by layer, reducing the apertures of screen holes of the screens layer by layer, and reducing the particle sizes of the mud blocks when the mud blocks pass through the screen holes of the screens layer by layer; meanwhile,hot air is introduced below the screen so that the mud blocks are repeatedly heated and dried by the flowing hot air in the friction movement and falling process, and finally powder particles with the particle size being smaller than 1.5 mm and the water content being 9%-10% are obtained; according to the invention, the drying of the mud is decomposed into three processes of preliminary drying, granulation and rounding which are carried out step by step, and the specific surface area of powder particles is rapidly increased in the later two processes so that the rapid volatilization of wateris facilitated, the drying speed is increased, and the energy consumption is reduced.
本发明涉及陶瓷湿法制粉技术领域，特别是一种陶瓷制粉工艺及其系统；陶瓷制粉工艺包括以下步骤：步骤S1、把泥料进行烘干处理，得到含水量为12%～14%的泥块；步骤S2、将泥块逐层摩擦依次设置的2个以上的筛网，筛网的筛孔的孔径逐层变小，泥块在逐层通过各个筛网的筛孔时粒径逐层变小；与此同时，在筛网的下方通入热风，使泥块在摩擦运动和下落过程中被流动的热风反复加热烘干，最终得到粒径小于1.5mm，含水量为9%～10%的粉料颗粒；本发明把对泥料的烘干分解成在初步烘干、造粒和磨圆这三个过程中逐级进行，在后两个工序中由于粉料颗粒的比表面积迅速增大，有利于水分快速挥发，从而提高了烘干速度，减少能量的消耗。
