A kind of bentonite processing method

Abstract

The invention discloses a bentonite processing method, comprising: a, ore dressing; b, raw material testing; c, artificial ore dressing; d, ore crushing: bentonite raw ore after artificial ore dressing needs to be crushed by a crusher or a vibrating screen; e, Drying: the bentonite raw ore obtained by manual screening is dried in a natural sunlight environment to keep its moisture content at 20-30%, and then stored in a pile with a forklift, waiting for the next step of grinding; f, grinding: the bentonite Put it into the grinding machine, grind the bentonite into the required particle size; g, fineness sampling inspection; h, comprehensive inspection: if the fineness inspection is qualified, a comprehensive inspection should be carried out, and the montmorillonite content, particle size, and heavy metal content of the product should be checked. , Whether there are harmful substances, water content, etc. are tested, and the qualified montmorillonite products are packaged and stored, and the unqualified ones are returned to the principle storage area to wait for reprocessing; i. Packaging and storage.

Description

technical field [0001] The invention belongs to the technical field of bentonite processing, and in particular relates to a bentonite processing method. Background technique [0002] Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. The montmorillonite structure is a 2:1 crystal structure composed of two silicon-oxygen tetrahedra sandwiching a layer of aluminum-oxygen octahedron. Due to the formation of montmorillonite unit cells There are some cations in the layered structure, such as Cu, Mg, Na, K, etc., and the interaction between these cations and the montmorillonite unit cell is very unstable, and they are easily exchanged by other cations, so they have good ion exchange properties. It has been used in more than 100 departments in 24 fields of industrial and agricultural production in foreign countries, and there are more than 300 products, so people call it "universal soil". [0003] When bentonite is processed, it is necessary to...

Problems solved by technology

[0003] When bentonite is processed, it is necessary to grind the bentonite. After grinding, there is usually a lot of dust adhered to the inner wall of the grinder. Since the dust is squeezed on the inner wall of the grinder, the dust adhered to the inner wall of the grinder is inconvenient to clean. At the same time, due to the relatively compact internal structure of the grinder, it is more inconvenient to clean the grinder, which affects the grinding effect of the grinder
