Desulfurization process of limestone powder production


Can make the products water ≤ 1, to meet the quality requirements. In the winter rainy season, to strengthen the management of raw materials into the plant, while there is a spare fuel stove to prepare for high water use of limestone. In the belt into the grinding machine has a magnetic separator, to prevent the iron into the vertical mill. By high concentrations of air box pulse bag filter to collect down the limestone powder products, the screw conveyor, bucket elevator into a limestone powder storage library, the library has a pulse single filter on top of the dust emission. Reservoir bottom has a bulk machine,[link widoczny dla zalogowanych], the product shipped directly from the factory cars in bulk. To prevent compaction of limestone powder in the library, library facilities with hot air inflatable, inflatable Timing on loose limestone powder. Heat by electric heaters, the process shown in Figure l yoga l set 1 \, l one by one 7 '= a - a small 3.1 11 Chuan principles and characteristics of the West of the program is to granular limestone ball through the impact of the mill , abrasive into a powder, the grinding of materials provided by the bucket elevator into the mill, a q a map 1J_】 efficient separator separator, separating out the meal back to re-grinding mill, fine powder with the flow of qualified by high concentrations of bag filter to collect the finished product. Hefei Cement Research & Design Institute of the DS and the strong research and development of high-efficiency separator functions to meet the requirements of the production of limestone powder. Program is the traditional ball mill grinding process, mature technology, convenient control,[link widoczny dla zalogowanych], and swollen \L ,,,~. _ ~ J-u. . . . . . . _. Sichuan ¨ b l ~ - ~.

Returned by the transportation equipment meal grinding, the process shown in Figure 2. 4 * m a j a http. 'At present, domestic flour mill has been put into the desulfurization limestone is mostly used ball mill grinding equipment,[link widoczny dla zalogowanych], such as Hebei Hengshui Power Plant, Tangshan, Nanjing limestone flour mill, Taicang Port power plants. Few have been put into the vertical mill vertical mill are mostly imported. Expensive imported vertical mill, it is difficult for users to accept. Recent years, with vertical mill to improve manufacturing technology, especially the improvement of wear-resistant materials and control technology to upgrade and improve the reliability of the vertical mill. Its reliability has been prepared cement raw materials, non-metallic mineral industry, grinding powder, pulverized coal power plants and steel mills grinding multiple authentication. Currently,[link widoczny dla zalogowanych], some limestone in the construction of the desulfurization of domestic flour mill vertical mill has begun to use programs such as the Wenzhou Power Plant, Changxing Power Plant, Xuzhou pond plants, Datang Power Douhe power plant desulfurization systems are made of vertical mill using the program. Now the annual output of 150,000 t of limestone powder (325 mesh sieve (10) production line, for example, the two grinding system program is shown in table 1. From the program can be seen comparing Table 1: Ball program is adaptable to the raw materials and reliable operation, the ball mill vertical mill program investment and more than 100 million. But the process is simple vertical mill, grinding, high efficiency, low energy consumption figure 2'f swelling, grinding media consumption is low, the total cost of the long term or cost-effective. domestic vertical roller mill in grinding effect on the limestone powder must be put into operation to show up.
