Montmorillonite grinding device with purification function

Abstract

The invention discloses a montmorillonite grinding device with a purification function, which comprises a raw material grinding module, a constant temperature stirring module and a centrifugal drying module connected in sequence; wherein, the raw material grinding module is used for grinding and screening montmorillonite raw materials; The constant temperature stirring module is used to mix the montmorillonite raw material and water into the raw slurry, and stir the raw slurry at a constant temperature; the centrifugal drying module is used to centrifuge and dry the upper raw slurry. Compared with the prior art, the purification equipment provided by the present invention realizes intelligent purification of montmorillonite, reduces labor force, and saves cost and time.

Description

technical field [0001] The invention relates to the technical field of montmorillonite purification, in particular to a montmorillonite grinding device with a purification function. Background technique [0002] Montmorillonite is widely used because of its special water absorption, water plasticity, cohesiveness and strong ion exchange, mainly in machinery, chemical industry, health care and other fields. However, natural montmorillonite contains non-clay silicate minerals such as silicon dioxide, opal, feldspar, gypsum, and calcite, and the purity is poor, and the content of montmorillonite is usually 50%-70%. The production process of montmorillonite purification is as follows: raw ore→drying and dehumidification→hand selection of impurities→soaking and hydration→stirring and pounding→fishing and discarding floating matter→self-flowing and sieving to remove impurities→cycling to remove sand→secondary spinning Flow→overflow grading→filtration dehydration→air-drying harden...
