The invention provides a production process of a ceramic tile, which comprises the following steps: by taking 2% of black mud, 3% of dolomite and 94% of bauxite sand as main materials and sodium metasilicate pentahydrate, barium carbonate and PVA as auxiliary materials, grinding and screening, deironing and sieving, spraying and granulating, mixing and stirring, feeding into a powder bin, pressing and forming, firing, inspecting and warehousing, and the like. The preparation method comprises the following steps of: effectively grinding by using a wet-type ball-milling processing mode, enabling the fineness of slurry to be more than 600 meshes (medium aluminum) or d90 to be 10mu m (medium-high aluminum) according to the specified time, simultaneously screening the raw materials for multiple times, increasing the plasticity of ceramic tiles or ceramic balls by using PVA (Polyvinyl Alcohol), and finally forming green body powder subjected to spray granulation by using a required mold in an isostatic pressing mode.
本发明提供了一种瓷砖的生产工艺，以黑泥2％份、白云石3％、铝矾土砂料94％为主材，以5水偏硅酸钠、碳酸钡、PVA为辅料，经过研磨筛选、除铁过筛、喷雾造粒、混合搅拌、入粉料仓、压制成型、烧制检验入库等一系列工艺步骤，将主辅料配合后，用湿式球磨加工方式，有效研磨并按规定时间，把浆料细度达，600目以上（中铝）或d90达10um(中高铝)，同时对原料进行多次筛选，利用PVA增加瓷砖或瓷球的可塑性，最后把喷雾造粒的坯体粉料，用所需模具、以等静压的方式成型。
