Gypsum as cement retarder requirements So3 (sulfur trioxide) content greater than 35%, adhesion water content of less than 5%, the ignition loss of less than 2%, in line with the above requirements can be used gypsum cement retarder, setting time of cement to meet the requirements in the standard, with the gypsum in the cement industry. First: high purity calcium sulphate dihydrate content can be adjusted, less impurities compared with natural gypsum, high quality. Second: the microstructure of gypsum makes it require less water, the water evaporates after the formation of small holes, have an advantage on the mechanics, and less corrosive chlorine ions and other impurities, which can improve the strength and durability of gypsum pressure ball machine introduced Gypsum pressure ball gypsum powder will function, without the need to add any binder lump-pressed into a ball, and into a ball rate of 95% out of the ball pressure hardness strong, transportation and handling should not be broken, then supply to replace natural gypsum cement solidifying agent, the ball finished gypsum purity guaranteed, direct forming, high strength into a ball, for a variety of transportation, improve product transport capacity; compact gypsum pressure ball machine structure, easy maintenance, simple operation, short process, low energy consumption, low failure rate, the main part of the roll 2 9 chromium molybdenum vanadium steel casting, greatly improving the wear resistance and voltage capability of the machine with a longer service life. Pressure the ball machine gypsum powder machine has the ability, without the need to add any binder, the one-time pressed into a ball, high yield gypsum pressure ball machine manufacturers, hardness, has been in the country more power plants and cement plants put into use, with good results. In terms of raw gypsum itself, or from the results analysis of the product, the application of flue gas desulfurization gypsum in the building materials industry are very extensive. However, because gypsum-containing water large, in terms of pressure the ball into blocks has been a problem. Technology determined to begin technical research, I plant in recent months after the experiment 20t / h Gypsum pressure ball machine manufacturers, finally mastered the gypsum pressure ball humidity and water power needed 30t / h Gypsum pressure ball machine manufacturers , development and production of gypsum dedicated pressure ball machine, the device is capable of gypsum powder, without the need to add any binder lump-pressed into a ball, and as the ball was above 95%, the hardness of the pressure out of the ball is Strong, transportation and handling should not be broken, supplied to the cement plant instead of natural gypsum used to make cement retarder. Along with the breakthrough technical difficulties, our success with many customers signing yield 30 tons gypsum pressure ball machine manufacturers implementing the gypsum pressure ball production line, creating a new situation gypsum pressure the ball, the real recycling of waste residue turning waste into treasure. I plant with simple production line to provide our users personally own raw materials to the factory site test machine, for further information, may be the production site field trips. 30t / h Gypsum pressure ball machine manufacturers _ Hongxin mining gypsum pressure ball machine manufacturers provided by the Zhengzhou City Hongxin Mining Equipment Co.
