Cement Clinker Grinding Unit
Cement Clinker Grinding Unit Introduction:
Vertical milling machine set crushing, drying, grinding, grading conveyor in one grinding roller compacted materials directly in the disc of its grinding, hydraulics equipment stable and efficient work.
Cement Clinker Grinding Unit Working Principle:
Motor through reducer drive disc rotation, the hot air from the inlet into the vertical mill, the material falls from the feed opening disc central centrifugal force, its material the millstones edge from the millstone central to moving on after disc annular groovewhen subjected to the grinding rollers of the roller compacted and crushed, the crushed material to continue to move to the refiner disk edge, until it is taken away by the air ring at the gas stream, while the large particulate material falling to the disk on continued pulverization. The flow of material through the upper part of the separator, the effect of the guide vanes, the coarse material from the cone bucket falls millstone, powder together with the airflow in the grinding, and collected by the dust collector system, a powder was collected i.e. mill to grind the product for the legislature. The material in contact with the gas in the housing during the drying, to achieve the desired dry product humidity. By adjusting the separator-oriented point of view of the fan blade (small vertical mill is not adjustable) and the rotational speed of the rotor of the separator, the products required thickness can be achieved.
Cement Clinker Grinding Unit Features:
Vertical milling machine compared with other grinding equipment, has the following characteristics:
1, high grinding efficiency, using the the material bed squeezed crushed principle, by the RCC, shear, impact the role of material in the mill. Mill airflow finely ground materials in a timely manner to bring out, to avoid excessive grinding, the material stays in the mill time is generally 2-4rain, for 165% of the ball mill grinding efficiency, power consumption can be reduced by about 30%.
2, high drying efficiency, the hot air from the annular slit spray people, high wind speed, large ventilation cross-section mill, small resistance, using the preheater exhaust gas can be dried to moisture content of 8% of the material, if hot stove can be drying aqueous 15% to 20% of the materials.
3, people grinding materials a large size, generally up to 5% of the diameter of the grinding rollers, the large mill feed size of up to 150 ~~ 200mm, equipment and technology superior performance, single output, high rate of operation of equipment, metal wear than ball mill.
4, grinding material adaptable, can be used for grinding a variety of raw materials and fuels, such as limestone, sandstone (Si02> 90%), coal, cement clinker, blast furnace slag, etc.. Regardless of their grindability, abrasiveness how, through internal restructuring of the mill and reasonable operation, can produce different fineness, different than the surface area of qualified products.
5, the process is simple, compact layout, low cost of routine maintenance, can be open-air setting, infrastructure investment is about 70% of the ball mill.
6, the overall tightness small dust, low noise, and superior environment.
7, finished product quality control is fast, flexible adjustment of product, easy operation intelligent, automated.
8, shortcomings of vertical mill is not suitable for the grinding of hard and abrasive materials, wear parts expensive than ball mill, ball mill, hoist it replaced, the powder equipment compared to the total amount of maintenance is still seems simple maintenance, easy and workload.
Cement Clinker Grinding Unit Applications:
Vertical milling machine applications: large production of special steel plants, thermal power plants, cement plants, coal preparation and coal gangue powder production; dedicated power plant desulfurization limestone milling; hardness number of non-metallic minerals industryone hundred kinds of large-scale ore powder production preparation; special steel mill slag and blast furnace slag grinding plant slag and fly ash; the dedicated glass fiber industry quartz, pyrophyllite powder yield high fineness grinding; dedicatedproduction powder production of a variety of stone raw materials for the stone industry; hundred kinds of industries of various materials production powder the industrialization preparation. At the same time in the grinding of slag powder and cement clinker pre-grinding, also has good prospects for development.
