Gypsum-site work plan for the technical requirements as gypsum cement retarder is: So3 (sulfur trioxide) content greater than 40%, the content of less than 7.4mg / kg, gypsum pressure ball machine, attached to a water content of less than 5% loss on ignition is less than 2%, in line with the above requirements can be used as cement retarder gypsum, cement setting time to meet the standards, the use of FGD gypsum in the cement industry, the first: high purity calcium sulphate dihydrate content Adjustable, less impurities compared with natural gypsum, high quality; second: microstructure gypsum less water makes it necessary, after the water evaporates to form small holes, gypsum pressure ball machine professional manufacturer, have advantage on mechanics, and corrosive chlorine ions fewer impurities, which can improve the strength and durability. Studies have shown that a certain amount of FGD gypsum calcium carbonate and more water-soluble salts, mixed with gypsum cement normal setting time, mechanical properties and stability of cement has a positive effect. But gypsum is generally 10-17% moisture content, gypsum pressure ball machine manufacturers, adhesive strength, so the handling, lifting, during transportation easily attached to the device, resulting in product material, blockage, if directly used cement production will result in the emergence of the material transport poor, mixed evenly, when the production of 15 tons gypsum pressure ball machine technology, the normal production and other issues. The wet form of gypsum to be processed into a ball to make it happen varying physical properties, reduced adhesion between each material, increase mobility can completely change the gypsum present in the cement production process problems. The gypsum powder extrusion process is to increase the particle size, in this process, the powder particles of the powder by mechanical occlusion pressure to form a ball. 20150622020101 Zhengzhou Hongxin professional Xinjiang gypsum pressure ball machine factory direct. I plant and the success of the implementation of a number of customers signed gypsum pressure ball production line, creating a new situation gypsum pressure the ball, truly a waste recycling plant, turning waste into treasure. The machine can be a variety of slag, metal powders, coal, coke and other materials can be suppressed, so that the molding. Because of the mandatory squeeze rollers, so that the product has a high density, high strength, high hardness of three high characteristics, and use of the machine roll 650mn rigid material with good wear resistance. Effectively improve the roll life. Shanxi produced 15 tons of gypsum ball press machine (certified), gypsum pressure ball machine provided by the Zhengzhou City Hongxin Mines Ltd. when. Zhengzhou City Hongxin Mines Ltd. (www.zzhxkyjx.com) is a leader in Zhengzhou, crushing grinding equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Hongxin leader in mining equipment with the staff warmly welcome all inquiries negotiations to create Hongxin mining equipment better future.
