Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

Carbothermal Reduction of Barium Sulfate-Rich Sludge from

Nov 01, 2013 The alkali–barium–calcium (ABC) desalination process is basically an integrated lime/limestone neutralisation process combined with a sulfate removal stage using barium carbonate (BaCO3), and a sludge processing stage. The BaSO4/CaCO3 sludge generated during the desalination stage is treated to recover BaS and CaO by dewatering and thermal processes, with the ultimate goal

Barium sulfate Wikipedia

Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications.

Since barium sulphate is highly insoluble in water only by carbothermal reduction of barite (barium sulphate) it changes into water soluble barium sulphide. Use of sodium nitrate as a catalyst to enhance the percentage of reduced barium sulphide is quite encouraging. It is a simple industrial method and affects the economy of the industries.
