Steps For Ericsson of Coal Mill
steps for ericsson of coal mill
Mill Machine:
The mill is widely used in metallurgy, building materials, chemicals, mining minerals in areas such as grinding materials processing. According to the fineness of the grinding of materials and discharging materials fineness, milling machines can be divided into Raymond Mill, vertical pendulum mill, high pressure hanging roller mill, high pressure micro powder mill, Straight Centrifugal Grinder machine, super pressure trapezium mill, three-ring medium speed mill six mill type.
Coal Mill:
Mill, vertical mill, high pressure hanging roller mill, medium-speed micro-grinding, super pressure trapezium mill, Raymond and other models, Coal is the coal crusher and ground into a pulverized coal machinery, it is pulverized coal boiler auxiliary equipment. The process of grinding coal coal is broken and its surface area is not coal pulverizer.
The increasing process. To increase the surface area, must overcome the binding force between the solid molecules, therefore, requires the energy consumption. Coal in the mill, mill made of pulverized coal, mainly through the crush, crushed, and crushed in three ways. Which crushed the process of the energy consumed most province. Pulverization process is the most expensive energy. A variety of coal mill in the milling process, both the above-mentioned two or three ways, but what mainly depends on the type of coal pulverizer. Type a lot to the pulverizers, the speed of the coal grinding parts can be divided into three types, namely low-speed coal mill, medium speed mill and high-speed coal mill.
Coal Mill Applications:
1, Special steel plants, thermal power plants, cement plants coal preparation and coal gangue yield powder production;
2, Dedicated power plant desulfurization limestone milling;
3, Non-metallic minerals industry a variety of hardness hundreds of large-scale ore powder production preparation;
4, Special steel slag and blast furnace slag, power plants, slag and fly ash grinding;
5, Special glass fiber industry, quartz, pyrophyllite powder production of high fineness of grinding;
6, Special stone industry a variety of stone raw materials production powder production;
7, Industrialization of the large yield of powder preparation of hundreds of kinds of industry, a variety of materials;
8, Pre-grinding mill slag powder and cement clinker, but also has good prospects for development.
Steps for Ericsson of Coal Mill:
Coal mill maintenance: maintenance work must be done every day, so as not to big problems later, after the maintenance work should adhere to often, and each stop, to check the mechanical ministries loose bolts, loose shall be strong, the amount of lubricating oil check, as the host before and after the bearing chamber, and on time meeting note, bearing chamber to inject lithium based lubricants Note axial end cap oil Tsui.
Coal mill maintenance: Equipment maintenance, do as the following:
1, check the host before and after the bearing chamber bearing lubrication conditions, such as grease fouling to clean is clean, you want to update the grease, to see the status of the bearing wear, and see whether it needs to be replaced;
2, Check the external bolts and sturdy;
3, Open the computer, check hit coal hammer wear situation, if a serious need to be updated;
4, Check the crushed parts of the ministries liner and the body mounting bolts loose, loose to be sturdy, liner wear serious replaced with new parts;
5, Check the fan blades connecting bolts loose, the leaves are badly worn, if any looseness should be solid or replace;
6, Check the burner internal clearance fouling repair the lining.
