Introduction

Barite crystal, which belongs to non-renewable mineral, is one kind of important industrial material. It is not only be used as white pigment, but also can be used in chemical, paper, textile packing and some other industries.

There are a series of studies, before starting the production. Firstly you need to analysis the mineral samples, and then engineers should survey the mineral district. When all base data are Identified, production line design will be easy and right design and equipments can greatly improve production efficiency and save lots of costs. In general, barite processing includes several steps. Most barite mining stone are from mountains, they are digged out and fed to barite crushing line. After repeatedly crushed by jaw crusher, impact crusher, cone crusher and other equipments, the size can reach to 0-30mm. Finally, the barite aggregates can be processed by Raymond mill, trapezium mill, vertical mill, super-micro mill and other mills ,and the barite powder size can reach to 350-2500 mesh.The mill is integrant machine in the processing of calcium carbonate and their properties directly decide the production costs. One good mill usually has advantages as follows: stable performance, convenient operation, low energy consumption, adjustable and controllable final size, widely used grinding materials, equipped with special dust collector. And dust emission concentration is lower than the national environmental regulations completely. Take SBM MTW series grinding mill for example. Because of its vertical structure, it covers a little area, by this way, it help investors save lots of foundation and workshop costs. Also, its compact structure, perfect transmission device and excellent sealing system can ensure its reliable performance and long service-life.
