Barite is a sulfate mineral whose main component is barium sulfate. Barite is mainly used in petroleum, chemical, paint, filler and other industrial sectors, of which 80%-90% is used as a mud weighting agent in oil drilling. Of course, with the rapid development of my country’s industry, the application field of barite is still It is constantly expanding.
Barite is a relatively common non-metallic mineral, and most of its uses are also widely known. Barite products in my country have different specifications and quality requirements according to their uses.
Barite powder and pharmaceutical grade barite products used as fillers for paints, coatings, plastics, rubber, etc. , not only need to have high purity, but also have a fine particle size. There are certain requirements for its whiteness, and the minimum should be greater than 85%; Barite powder is used to replace titanium dioxide and precipitated barium sulfate, and its whiteness should be above 92%.
Barite has low Mohs hardness, high density, good brittleness, and is easy to crush. Therefore, the ultra-fine crushing of barite mostly uses a dry process. Air jet mill can crush barite to 5μm, D97, but there are some problems in industrial production that need attention: jet mill has very high energy consumption in production, but its output is very low, which is fundamentally low. Can not meet the production needs of industrial enterprises; the jet mill is suitable for crushing products that require extremely high fineness, material hardness, and low output requirements. For products that require large-scale production in industrial production, such as barite powder , the use of jet mills obviously does not meet the requirements.
The LUM large-scale ultra-fine grinding machine launched by Shanghai Shibang Group can fully meet the requirements of barite ultra-fine grinding in product fineness , and the output is large, the energy consumption is relatively small, and the product fineness can be based on demand Free adjustment, complete set of equipment dust collection and dust removal system is quite complete, it is the best equipment for processing barite ultrafine powder in industrial production.
