Grinding Mills Introduction:
Vertical milling machine is widely used in cement chemicals, coal, electricity and other departments mill equipment. Has a small footprint, low energy consumption, low noise, the process is simple, compact layout, centralized pieces, drying, grinding, the powder is one of the advantages of modern cement raw material grinding device of choice. The world's earliest developed vertical mill is the Federal Republic of Germany Loesche (Loesche), the 1925 has a more mature design. After continuous development and improvement, the largest LM63.4 production of 840t / h, the disc diameter of 6.3m, the installed power of 5600kW, 4 grinding rollers.
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.
Grinding Mills 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.
Grinding Mills 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.
Grinding Mills System Process:
1, Single pulse dust collector open circuit system.
The raw materials of the system through the bucket elevator machine into the raw materials warehouse, weighed, fed to the lock Wind feeders, belt conveyor to ensure as much as possible after the removal of iron raw materials into the mill string wind. The products collected a pulse dust collector to reduce the number of units of equipment, to simplify the configuration of the system. Product collected screw feeder bucket elevator into the storage bin. The drying of the wet material into the mill.
2, The whirlwind plus pulse dust collector closed circuit system.
The system with the single difference of the pulse precipitator open system in that the product was collected with a cyclone to complete primer fan part of the gas is introduced into the mill for recycling, can reduce the work load of the system and the amount of gas through the precipitator, and ultimately The dedusting equipment available pulse dust collector.
3, Single pulse dust collector closed circuit system.
The distinction of the system with a single collector system, pneumatic conveying system is that the product is collected with the finished product into a storage bin, induced draft fan at the same time, most of the gas introduced into the mill for recycling.
Grinding Mills in China:
China is a big country, and could produce grinding mills every year, a large number of quality product is produced and sold around the world. The quality of grinding mills produced in China is guaranteed, and the price is relatively cheap. It is the best choice to buy grinding mills in China. But choose to buy grinding mills can not be blindly freeloaders, they should have chosen a large formal grinding mills manufacturer. So to protect the interests of buyers, and can provide the necessary technical support and maintenance services.
