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.

Processing technology

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.

Equipment needed

MTW Series Trapezium Mill

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.

Application field

1Weighting agent of drilling mud

Under the condition of underground pressure is higher, added to the mud barite powder is an effective measure to increase the mud weight.

2Lithopone pigments

Barite's requirements of producing lithopone BaSO4 content is greater than 95%, and should contain no visible color clutter.

3All kinds of barium compounds

The raw material can be manufactured as barite, barium oxide, barium carbonate and other chemicals.

4Packing industry

In the paint industry, barite powder filler can increase the film thickness, strength and durability.

5Cement industry mineralizing agent

Barite and fluorite compound mineralizer is incorporated in cement production ,which has a significant effect on promoting C3S formation and activation of C3S.

6Anti-ray cement, mortar and concrete

Replace the metal grids and build research nuclear reactor shielding, hospital X-ray.

7Road construction

Rubber and asphalt mixture containing about 10% barite has been successfully used for parking, is a durable paving material.

8Other

Barite and oil applied to the cloth manufacture linoleum reconcile; barite powder for refined kerosene and so on.
