The invention provides ceramic bentonite, which is prepared by the following steps: screening bentonite raw materials mined from bentonite ore, and removing impurities to obtain bentonite raw materials; crushing the obtained bentonite raw material, and adding a diluent into the crushed bentonite for dispersion; adding a sodium modifying agent into the dispersed bentonite to carry out sodium modification; purifying the bentonite subjected to sodium modification, and then covering the purified bentonite with ammonium salt; rinsing the bentonite covered with the ammonium salt, dehydrating the bentonite, adding a sodium modifying agent into the dehydrated bentonite again for sodium modification, and adding a water reducing grinding aid for crushing and milling after sodium modification is completed; and carrying out secondary dehydration on the crushed and ground bentonite, heating and drying the final bentonite, and packaging the bentonite product.
本发明提供一种陶瓷膨润土，所述制备工艺如下：将膨润土矿中开采出来的膨润土原料进行筛选，除去杂质，得到膨润土原料；将得到的膨润土原料进行粉碎，对粉碎完成的膨润土中加入稀释剂来进行分散；将分散后的膨润土中加入钠化剂来进行钠化；将钠化完成后的膨润土进行提纯，再将铵盐覆盖在提纯后的膨润土上；将铵盐覆盖后的膨润土进行漂洗，漂洗完成后进行脱水，脱水后的膨润土中再次加入钠化剂来进行钠化，完成后加入减水助磨剂进行粉碎磨粉；将粉碎磨粉后的膨润土进行二次脱水并加热烘干，进而得到最后的膨润土并包装。
