South Africa is the world's second largest vermiculite ore producer, only after the United States. South African vermiculite total reserve is about 73 million tons, accounting for 35.9 percent of the world's reserves. In addition, South Africa is the world's largest exporter of vermiculite. South African vermiculite annual export volume accounts for nearly 90% of world trade. In South Africa, among the domestic production of non-metallic minerals, vermiculite is a major foreign exchange mineral. The major producer of vermiculite is Palabora region, accounting for over 90% of vermiculite total reserve in South Africa.
According to different production requirements, product specifications of vermiculite are as follows:8-12MM ,4-8MM ,2-4MM ,1-2MM ,0.3-1MM ,40-60 mesh,60-80 mesh,80-100 mesh, 100 mesh, 150 mesh, 200 mesh, 325 mesh, etc.
With the development of vermiculite’s applications, South African abundant vermiculite resource has been extensively developed. And many vermiculite processing plants are built in recent years. In general, we need jaw crusher, impact crusher and vibrating feeder, vibrating screen as well as belt conveyor. After being transported from the mining site, the raw vermiculite mine needs store and select at first, to ensure the vermiculite continuous and stable quality fed into the follow process. In the primary crushing process, we usually choose jaw crusher to crush vermiculite ore into small size within 8 mm. Use vibrating screen to screen the crushed vermiculite into different sizes, and send suitable particles into the next step, while the other part returned for re-crushing. We recommend impact crusher as secondary crusher to crush vermiculite into small size less than 2 mm. At last, send crushed vermiculite to the mill for grinding.Customers can choose different kinds of grinding mill according to different requirements, such as vertical mill, trapezium mill, ball mill, and so on.
And you can choose the mobile vermiculite crusher, which gathers all the machines above together. Compared with traditional and fixed vermiculite processing line, mobile vermiculite crusher has many unmatchable features. It is designed with more reasonable and compact structure, which greatly reduces the occupying area. And compared with fixed crushing plant, mobile vermiculitecrusher can work without disassembly, transportation and installation, soit can greatly reduce the investment. The crusher can move to vermiculite mining area without any environment limit to reduce transportation cost and foundation building cost. It is more flexible and adaptable. And it is easy for installation and maintenance. Our efficient mobile vermiculite crusher adopts advanced manufacturing technique and high-end materials. So it has higher carrying capacity and more reliability. It is easy to adjust the size of the final products. And the crushed materials are in good particle shape. According to different production requirement, it can match with other equipment easily.
According to a series of processing, vermiculite has a wide application. Its main purpose is still to make building materials. In the U.S. consumption structure, vermiculite accounts for 52% used as mortar and cement mixing materials and lightweight concrete aggregate. In English, 40% of vermiculite is used asconcrete, plastering mud, and cement coagulant.It can also be used as adsorbents, fireproof insulation materials, machinery lubricants, soil improvers, and so on.
