DH series of dry roll granulator is the use of dry roll technology, ≤5% moisture content of the powder material is compressed into tablets or block, and then granulated by crushing, screening process, so that chip block material into line with the requirements of granular materials. Dry roll granulator mainly by way of external pressure, so that the material is forced through two opposing rotating roller gap, compressed into tablets forced massive, pulverized coal in the process of rolling granulator to roll granulator, the material actual density can be increased 1.5 to 3 times the granulator, so as to achieve - given particle strength requirement. Gypsum is an industrial byproduct granulated gypsum flue gas containing sulfur fuels (coal, oil) after combustion desulfurization purification obtained. From the beginning of the 1990s gradually in thermal power plants using limestone - gypsum wet flue gas desulfurization purification, followed by a yearly discharge a large amount of solid by-product of a gypsum, if it is not effectively utilized, the not only occupy a lot of land, it will cause secondary pollution to the environment. Although the physical and chemical characteristics of gypsum and natural gypsum same theory can replace natural gypsum as a raw material, in order to reduce the excessive consumption of natural resources, especially China, as the largest producer of cement, as cement retarder and mineralizing agent, fully able to realization of gypsum in the cement industry all consumed dry granulation machine manufacturers, but at present most of the gypsum stack storage is still mainly based, by the majority of cement producers failed to scale the use of reason fertilizer granulator mainly gypsum powder was wet, the moisture content is high, and has a high viscosity, which easily adhered to the transport equipment in the logistics process. Therefore, the company starting from gypsum production process, according to the thermal power plant thermal test data, after many experiments, the development of the use of gypsum instead of natural gypsum, gypsum formation of the efficient use and recycling, the establishment of cement retarder, gypsum flour, gypsum products, comprehensive utilization of industrial chain. Pulverized coal granulation machine roll granulator, Ding Zhuo dried (certified), granulating machine supplied by Changzhou Drying Equipment Co., Ltd. Ding Zhuo.
