Bentonite preparation process with short sand mixing time
The invention discloses a bentonite preparation process with short sand mixing time. The bentonite preparation process comprises the following steps: step 1, artificial mineral separation; step 2, ultrasonic cleaning; step 3, ore crushing; step 4, airing and drying; step 5, mineral aggregate heating; step 6, extrusion and sodium modification; step 7, grinding for powder forming; step 8, grading and screening; step 9, comprehensive inspection; and step 10, packaging and warehousing. According to the process, heating and heat preservation are conducted on fine ore, tannic acid is added, the extrusion sodium modification efficiency is improved, the sodium modification time is saved, the working efficiency is greatly improved, primary cleaning and ultrasonic cleaning are conducted on the ore raw materials, soil and impurities on the surfaces of the ore raw materials are greatly reduced, and improvement of the product impurity is facilitated. Cyclone classification is carried out on the semi-finished bentonite product, and re-grinding classification is carried out on the semi-finished bentonite product with unqualified fineness, so that the fineness and uniformity of the product are guaranteed, the sand mixing time is shortened, and sand mixing is facilitated.
本发明公开了一种混砂时间短的膨润土制备工艺，包括以下步骤：步骤一，人工选矿；步骤二，超声清洗；步骤三，矿石粉碎；步骤四，晾晒干燥；步骤五，矿料加热；步骤六，挤压钠化；步骤七，研磨成粉；步骤八，分级筛选；步骤九，综合检验；步骤十，包装入库；该发明通过对细小矿石进行加热保温以及单宁酸的加入，有利于提升挤压钠化的效率，节约了钠化的时间，极大的提高了工作效率，通过对矿石原料进行初步清理以及超声清洗，大大减少了矿石原料表面的泥土和杂质，有利于提高产品的纯度，通过膨润土半成品进行旋风分级，细度不合格的重新研磨分级，有利于保证产品的细致均匀，有利于缩短混砂时间，便于混砂。
