Coal gangue is an common industrial solid waste in industrial production, with the strengthening of environmental protection power, coal gangue resource utilization has been seriously, to speed up the coal gangue utilization value, is conducive to the ecological environment, enhance the coal gangue market value for the society and make greater contributions to the economic construction. Vertical grinding roller mill widely used as coal gangue powder production line, also progresswith the development of the industry, highlighting the advantages of coal gangue vertical grinding roller mill of high efficiency, excellent quality, to make coal gangue vertical grinding mill according to each selection program, to help customers create huge market profit.
First, the application value of coal gangue
1. Coal gangue can be used for power generation and gas making. Generally, medium carbon to high carbon gangue is used as fuel with calorific value greater than 3768.12J/kg, and to generate through back pressure steam generator is driven by a boiler. There are a number of coal gangue power stations in our country in operation.
2. The production of basic aluminum chloride and sodium silicate, according to research, gangue can be used in the same process to produce basic aluminum chloride (Al2 (OH) nCl6-n) and water glass (Na2SiO3).
3. The preparation of polymer aluminum chloride. It is reported that the technology of producing poly-aluminum chloride from coal gangue as raw material by acid dissolution is mature. Its technological process can be divided into crushing, roasting, continuous acid dissolution, condensation crystallization, boiling decomposition and water distribution polymerization.
4. The cement is made with coal gangue, and the coal gangue has been widely used in the production of cement. The coal gangue content in the cement can reach 30%, and the coal gangue can also be used for the preparation of the quick coagulation cement. Coal gangue, limestone, fluorite, gypsum and iron ore are used as raw materials.
Second. The price and advantage of coal gangue vertical mill
Vertical mill is high quality milling equipment developed by Guilin Hong Cheng according to the actual needs of slag, coal gangue, activated carbon, calcite and other field, it is integration of drying, grinding, classifying, transportation as one, simple process, less equipment system, compact structure, layout area is small, only 50% of the ball mill, can be open layout, low construction cost, directly reduce the investment of enterprise, the whole system is small vibration, low noise, negative pressure operation, no dust spill, is the best powder making equipment often used in coal gangue powder making field, in line with the new energy-saving technology advocated by the state.
