Barite is a kind of important Ba-mineral, with high specific gravity(4.3-4.7) and low hardness(3-3.5). Its chemical property is stable, insoluble in water. It can be used as white paint, as well as industrial sectors such as chemical engineering, paper making, weave padding ,etc. In glass production, it is used as fluxing agent which can increase the radiance of glass. 80% -90% of its application is for oil drilling mud weighting agent.
Technological process of barite production
According to the requirement from the downstream industry, the barite powder size 325mesh and much ultrafine powder is quite popular in the market. This size range process technology also becomes the main technology in barite powder process.
1. Big barite stone will be crushed to smaller size by small jaw crusher or impact crusher, which is suitable to the mill inlet;
2. After crushing, the suitable stone size will be transported to MTW ,MTM or LM grinding mill;
3. Barite powder is grinded in the grinding mill. The qualified powder will be collected after classifying, the unqualified powder will be sent back for regrinding.
4. Packing and storage for finished powder.
For non superfine barite powder, Shibang recommends you use MTW or MTM grinding mill; for ultra-fine powder production line, Shibang SCM series ultrafine mill is the best choice.
This mill is widely applied to the mineral products into powder in different industries, such as metallurgy, building materials, chemical industry, mining, etc.
It has been widely applied in paint, paper making, pigment, rubber, plastic, padding, cosmetic, chemical supplies, etc.
Due to the special nature and low development cost of barite, more and more people pay attention to it gradually. The development of modern industry has much strict requirement on the barite purity, whiteness and fineness. With the development of science and technology and the deeper study, much property of barite has been revealed. People begin the process of grinding barite to powder, beneficiation, and surface modification, etc. These respect has much economic benefits.
