Product overview
The impurity components of industrial by-product gypsum are diversified, the raw materials of gypsum in different regions are different, and the raw materials in the same region are also different, and the product quality can not meet the quality requirements of the products after the ordinary gypsum powder quality index can not meet the quality needs of modern gypsum building materials; Due to the complex preparation process, low yield and high cost of high strength gypsum powder, it is difficult to be widely used in the market. According to the characteristics of industrial by-product gypsum, by adjusting the production line technology, optimizing the production line equipment and changing the existing technical conditions, the production line of mixed phase high strength gypsum powder and mixed ordinary high strength gypsum powder are optimized.
1, the production line intelligent manufacturing equipment accounted for more than 50%, the production line equipment self-matching rate of more than 85%, 100% of the production line equipment technical change to gypsum building materials special equipment,
2, compared with the traditional high-strength gypsum powder production line to save more than 60% of the construction funds, mixed ordinary high-strength gypsum powder production line construction funds, increased on the basis of the ordinary gypsum powder production line within 30%, the production capacity can reach 1 million tons;
3, with drying, high-strength calcination, energy-saving application, aging homogenization technology, production according to the margin design, a production line can produce more than two categories of different products; The use of personalized customized solutions, the entire production line up to yield, high quality constant;
4, the whole line of negative pressure operation, drying, calcination, waste heat utilization technology can save a lot of money; The dust removal adopts multi-stage high temperature dust removal system, has a unique whole production line corrosion technology, and the exhaust emissions meet the environmental protection standards of various regions;
