According to different uses, the price difference of barite after processing into powder is relatively large, mainly for three major purposes.
1. Paint, zinc bismuth, ordinary glass and rubber filler:
Production of paint (BaSO4: 90 ~ 95%), barite powder filler can increase film thickness, strength and durability. Need less than 325 mesh, requiring high whiteness
Production of zinc antimony white (BaSO4: 95 to 98%) SiO2 <1%, the less the Al2O3, the better. The preparation of zinc-white barite requires a BaSO4 content of greater than 95% and should not contain visible colored debris.
Ordinary glass (BaSO4: >96%) SiO2<1.5%, Al2O3<0.15%
The rubber filler (BaSO4: >98%) is less than 325 mesh and must not contain Mn, Cu or Pb impurities.
2. Chemical barite powder index
Project indicator percentage
BaSO4SiO2Fe2O3Al2O3 water soluble salt
Class I 95<1.5<0.5<1<0.3
Level II 90<2.5<1.5<2<1.0
Level III 85<2.5<1.5<2<1.0
3. Oil drilling grade barite powder index (90% use)
Density, g/cm ≥ 4.2
Fineness, -200 mesh%
Water soluble matter, %≤0.1
Clay effect, Pa.s ≤ 0.125
Barium sulfate content, %≥90
Now subdivided, barite powder is also used in pesticides, steel surface quenching, phosphors, fluorescent lamps, fluxes, grease additives, etc.
Paving materials stress the buried pipelines in the marshes, replacing the lead plates for shielding of nuclear facilities, atomic energy plants, X-ray laboratories, etc., extending the life of the pavement
Barite Powder Grinding Mills
For barite powder making,there are three main kinds of grinding mills for your choice:
Shanghai Clirik Machinery Co., Ltd is one of the most professional mining use machines manufacturers in China. R&D several stone powder grinding mill by ourselves. For more details of barite powder grinding mills welcome to contact us freely. WhatsApp: +8613917147829
For anti-radiation mortar and concrete barite, the content of BaSO4 should be no less than 80%, and the impurities such as gypsum, pyrite, sulfide and sulfate should not exceed 7%.
