Vertical Roller Mill Introduction:
Vertical roller mill (Vertical Mill) is to solve industrial mill output and low energy consumption and higher technical problems, absorbing advanced technology in Europe and combined with my years of advanced milling machine design and manufacturing concepts and market demand, after years of painstaking design The improved large grinding equipment. Widely used in the pyrophyllite powder, glass fiber industry production of high fineness of grinding; large production of the coal industry, coal gangue powder powder production; a variety of stone raw materials of stone industry production powder production; non-metallic minerals industry low production preparation of large-scale hundreds of medium and high hardness of ore powder; hundreds of kinds of other industries, a variety of materials production powder preparation.
Vertical roller mill set of crushing, drying, grinding, grading conveyor in one system is simple, compact layout, covers an area of approximately 50% of the milling system, and open-air arrangement, a significant reduction in investment costs. Powdered materials can be used to ground into a massive, granular and powdered raw materials required.
Working Principle:
Motor driven disc rotation speed reducer, while hot air from the air inlet into the vertical roller mill, the material falls from the feed opening disc central, under the influence of centrifugal force, the material from the disc central to the disc edge mobile after the disc on the annular groove , by the grinding rollers of the roller compacted crushed, crushed materials continue to move to the disc edge, until the air ring at the air flow away, while the large particulate material falling into the disc to continue to smash. Airflow in the material through the upper part of the separator, the role of the guide vanes, the crude material from the cone bucket fell the millstone on the powder together with the airflow out of grinding, the dust collected, the powder is collected that is, vertical roller mill grind the product. Materials in contact with the shell gas drying, to reach the humidity of the product required. By adjusting the angle of the splitter oriented blades (small vertical mill is not adjustable) and separation of the rotational speed of the rotor, we can achieve the required thickness of the degree of product.
Vertical Roller Mill Applications:
Large production of special steel, thermal power plants, cement plants, coal preparation and coal gangue powder production; dedicated power plant desulfurization limestone milling; the production of hundreds of large-scale ore powder preparation of the hardness of the non-metallic minerals industry; special steel slag and blast furnace slag grinding plant slag and fly ash; special glass fiber industry, quartz, pyrophyllite powder production of high fineness of grinding; special stone industry a variety of stone raw materials production powder production; industrialized preparation of materials production powder over a hundred kinds of industries. At the same time in the pre-grinding of slag powder and cement clinker grinding, also has good prospects for development.
Loesche Vertical Roller Mill:
The vertical roller mill is a common mill, there are many manufacturers can produce and provide quality content verticalCompare roller mill. The more famous is the dawn vertical roller mill and the Loesche content verticalCompare roller mill. Dawn vertical roller mill is by Liming Heavy Industry production, high quality and highly cost and practicality. Loesche vertical roller mill is also another excellent content verticalCompare roller mill. Both of which are widely used around the world.
Liming Vertical Roller Mill:
In contrast, the Mill of Liming Heavy Industry has the following characteristics:
1, low operating costs:
(1) high milling efficiency, vertical mill roller and the bed is rolling ground materials, low energy consumption, milling systems power consumption 40-50% lower than the milling system, but with the humidity of the raw material increases, section electric effect is more significant.
(2) metal loss is small, liner and roller using special materials, long life, reducing operating costs and high utilization.
(3) into the grinding material particle size, up to about 5% of the grinding roller diameter, generally 40 to 100 mm large and medium-sized vertical mill to dispense with two smash.
2, low construction costs:
(1) vertical mill process is simple and milling system covers an area can be reduced by about 50%, reduced by about 70% of construction costs, construction area is small, take up less space.
(2) vertical mill set of crushing, drying, grinding, grading conveyor in one system is simple and compact layout. Open layout, making the construction cost.
3, the operation is easy and reliable:
(1) is equipped with automatic control devices, remote control, easy to operate.
(2) to prevent direct contact with the device of the roller sleeve and disc liner of Quality Supervision, Inspection, and to avoid fragmentation rattling.
4, the drying capacity, vertical mill gas transport of materials, inlet air temperature in the grinding of larger water the material can be controlled, so that products reach the final moisture can be dried in the vertical mill water as high as 12 to 15% materials, even if it is dry milling, only drying water for 3 to 4 percent of the material.
5, the product quality is stable, uniform particle size distribution. Material in the mill residence time is short, easy to detect and control the product particle size and stone composition, product quality and stability.
6, easy maintenance, and repair fuel tank, turn the rotating arm, the roller, lining in a very short time be able to replace.
7, environmental protection, energy conservation; small vibration, low noise, less dust, the operating environment clean, to adapt to environmental requirements.
