Abstract

The invention discloses a processing method of hard bentonite, which belongs to the technical field of bentonite manufacturing, and comprises the following steps: alkalization of a storage yard: adding an aqueous solution of sodium hydroxide or sodium carbonate into a calcium bentonite storage yard to convert calcium bentonite into sodium bentonite; and drying: drying the bentonite to be processed by microwave drying equipment. According to the invention, the bentonite is dried by utilizing a microwave heating drying technology, the microwave drying speed is high, the drying time is short, and different from the conventional heating method which needs a long time to reach the required temperature, the required temperature can be rapidly reached by microwave heating, and the power, temperature and the like of microwave heating can be adjusted within a certain range; the device is simple in structure and high in automation degree, microwaves can heat and dry the interiors and the surfaces of bentonite blocks at the same time, and the problem that the bentonite blocks are not dried thoroughly, and the quality of finished bentonite products is affected is solved.

Description

technical field [0001] The invention relates to the technical field of bentonite manufacture, in particular to a processing method of hard bentonite. Background technique [0002] Bentonite is a kind of clay rock, also known as montmorillonite clay rock, often containing a small amount of illite, kaolinite, halloysite, chlorite, zeolite, quartz, feldspar, calcite, etc.; generally white, light yellow, Due to the change of iron content, it is light gray, light green, pink, brown red, brick red, gray black, etc.; it has waxy, earthy or greasy luster; some bentonites are loose like soil, and some are dense and hard. The main chemical components are silicon dioxide, aluminum oxide and water, and also contain iron, magnesium, calcium, sodium, potassium and other elements. The content of Na2O and CaO has a great influence on the physical and chemical properties and technological performance of bentonite. [0003] However, in the prior art, the hot air flow or heat conduction dryin...
