|Title||Ultrafine mill technology and the advantages of this technique|
The technology is the use of Raymond Mill for grinding materials, impact, shear, etc., will be below the material crushing to 1 o ~ 15 bm fine grain, make the material with large specific surface area, high surface activity, fast chemical reactions. The application of ultrafine grinding technique in the difficult treatment of gold mine is mainly through its powerful fine grinding ability to expose the microfines in the mineral and facilitate the subsequent cyanide leaching. Among them, ultrafine grinding technology has the advantages of low sulphide oxidation degree, no neutralization precipitation, good stability of arsenic in slag and environmental protection economy, and has broad development space.

Ultrafine grinding common equipment and industrial application foreground
At present, the Ore Milling Equipment at home and abroad mainly includes high-speed mechanical impact mill, airflow mill, ultra-fine mixing mill, vibration mill, etc. Ultrafine mill is grinding media use high strength mixing plant to make sports, forming many compressed the rotation of the dielectric layer, the medium layer can produce pressure and torque, so as to realize the high efficiency crushing of materials. Therefore, over the past 20 years, the superfine grinder has developed rapidly and has been widely used in various fields such as metallurgy, mining, non-metallic mineral materials and so on. At present, the research and application of ultrafine mill in China mainly around the non-metallic mineral powder manufacturing, such as difficult to deal with gold metallic ore stone mill powder production, lack of system research, industrial application are rare. With the development of ultrafine mill technology and the large scale of ultrafine mill equipment, ultrafine mill has a broad application prospect in metal ores.
Bentonite is a kind of Ultrafine Mill silica aluminate which is mainly composed of montmorillonite. The content of montmorillonite is 85-90%, so the function of bentonite is mainly determined by montmorillonite. With its excellent ion exchange, bentonite is widely used in industrial and agricultural production, covering 24 fields, including more than 100 departments, so it is commonly known as "soil". What are the specific USES of bentonite? Outlining below: low iron content bentonite, can very good act as good oil refining catalyst, bentonite, bentonite than ordinary plastic clay with the performance of the exchangeable ions, so can more faster to absorb moisture. Bentonite is easier to absorb the separated water, so the bentonite has more surface area compared with other clay, so it is widely used to remove the toxins and waste water treatment of edible oil. The expansion properties of bentonite are obvious, and they are well used in drilling mud and other professional fields. The adhesion force is very strong, and it can be used as a substitute for starch in the yarn sizing in the textile industry. In addition, it has good water resistance and can be used as filler in paper industry. Bentonite is the raw material for buildings, Bridges, roads and railways as well as concrete. However, the shape and size of natural bentonite are different, which limits the promotion of bentonite.
