Desulfurization gypsum emissions and accumulation volume showed a linear upward trend with the expansion of science and technology and production scale, accelerate the recycling of gypsum resources, and promote desulfurization gypsum widely used in more industrial areas has become the goal of many enterprises continue to pursue. In the desulfurization gypsum processing field, the application of desulfurization gypsum vertical mill is very common, now let’s come to know the composition of desulfurization gypsum.
1. Desulfurization gypsum composition
Also called the desulfurization gypsum flue gas, desulfurization gypsum, sulfur gypsum or Desulfurization gypsum and natural gypsum as main component, two water calcium sulfate CaSO4 2H2O, Desulfurization gypsum has the fine granular, the average grain diameter of 40~60m, the particles were short columnar, ratio of diameter to length in 1.5~2.5, the color was yellow, gray; content of calcium sulfate is generally above 90%, with free water in 10%~15%, which also contains impurities in fly ash, organic carbon, calcium carbonate, calcium sulfite and consisting of sodium, potassium and magnesium sulfate or chloride soluble salt etc.. Compared with natural gypsum powder, desulfurization gypsum powder has the characteristics of renewable, small particle size, stable composition, less harmful impurities and high purity.
In fact, desulfurization gypsum usage is still rich, can be used as cement retarder, gypsum can be used as building, can be used as composite cementations materials, along with the science and technology level, believe that the application value of Desulfurization gypsum will be continuously improved, so as to promote the useful material of the national economic development.
2. Characteristics of desulfurization gypsum vertical mill
When it comes to vertical mill, then we have to mention HLM vertical mill which developed by Guilin Hong Cheng, in order to meet the requirements of desulfurization gypsum, slag, cement, non-metallic minerals such as large-scale coal demand, Guilin Hong Cheng market-oriented, in-depth understanding of market development market, accelerate the pace of technological innovation, desulfurization gypsum vertical mill has the performance of drying, grinding, transportation, high grinding efficiency, low energy consumption, a single large production capacity, high degree of automation, long service life, the whole system is small vibration, low noise, negative pressure operation, no dust, using the new limiting device and a sealing device for grinding roller and the explosion suppression is better, sealing more reliable, more excellent performance, is advanced equipment to meet the demand of Desulfurization gypsum powder processing.
