What is the design difference for Great Wall slag wertical mill and coal vertical mill

Great Wall Machinery Company 57 years working on a large kiln and mill equipment manufacturing, has become China's leading grinding equipment integrated services for both Chinese and overseas customers around the building had an annual output of 20-100 tons of slag production, excellent market reputation.

　　At present, the main push of Great Wall vertical mill mainly include: slag vertical mill, cement vertical mill, raw material vertical mill, coal mill and so on , in order to better meet market and customer needs, the Great Wall machinery for coal vertical mill upgrade, today, Xiao Bian take you look at the upgraded coal slag vertical mill with the original mill What are the different?

　　the main push of Great Wall vertical mill.

　　First, the same point

　　Both present the same principle Kwai, material feeding device through fall on the disc, the disc surrounding material movement under the action of centrifugal force, several roller under the force of the material is crushed. Lin after the material powder is from the hot gas through the blowing wind ring, while the coarser material blown back disc re-grinding, on the other hand thousands of suspended materials can be baked, powder by hot air into the separator grading, qualified fines are collected BU to the precipitator, substandard meal back down to the disc .

　　Coal vertical mill and the slag vertical mill substantially the same structure, it is mainly composed of roller, disc, shaking bamboo, splitter, transmission, chassis, roller pressure mounted antelope, roller lubrication equipment Curse on the housing limit bit devices and other components.

　　Second, the synchronization point

　　Now introduce specific coal mill and slag mill differences:

　　1. The form structure of the disc-shaped disc foot and tire-shaped rolls sets.

　　2. The roll sleeve of wear to a certain extent can be used upside down, it helps improve the coal mill production, but also reduce wear and prolong its life.

　　3. The bracket portion is not connected to the bridge, supported mainly by the bellows on the bracket are connected together, and the only one inlet bellows can meet equipment needs.

　　4. The roller mounted curse Saikawa a swap-aligning roller bearings, seal chamber extends to the outer casing, not in contact with dust and gas, so as long as you can make a simple seal roller bearing not into dust, no sealing fan .

　　5. mill transmission parts, does not require auxiliary transmission devices.

　　6. separator section is provided on the upper shell explosion-proof valve to prevent the occurrence of an explosion pulverized coal in the mill, to ensure the safe use of equipment.

　　7. Because coal mill less slagging, so tap outlet with cover, no need to install slagging valve.

　　8. roller pressing part, I loaded the cylinder's seat with the holder is no longer a whole, but by anchor bolts secured directly to the coal vertical mill basis.

　　Review the application of both are extensive, coal vertical mill is mainly used for electric power, metallurgy, building materials, chemical industry, milling system, particularly for burning bituminous coal grinding system.

High-Efficiency Roller Mills's usage in nowadays

1. Traditionally, ball mills are used in cement industry for raw material, fuel and product grinding. Ball mills use an established technology and offer certain advantages. However, they have higher energy demands. By using an appropriate kind of the more efficient roller mill technologies – either as a replacement or in combination with ball mills – considerable energy savings can be achieved without compromising product quality. The following roller mill concepts are applicable to cement manufacturing:

   2. Vertical roller mills: In these mills materials are crushed between a rotating grinding table and 2 to 6 grinding rollers positioned slightly less than 90 degrees from the table surface and pressed hydraulically against it. Main advantages of vertical roller mills include:

relatively low power consumption (less than 10 kWh/t – for medium raw material hardness and medium fineness);

ability to combine grinding, drying (using waste heat from kiln system) and separation;

ability to manage larger variations in mass flow rate (30 to 100% of mill capacity).

Vertical roller mills are available in a wide range of capacities – 5 to 1200 t/h. 

According to National Development Reform Commission of China, VRMs have the following generic power consumption values when used for different purposes in a 6:

for raw material grinding, power consumption may range between 14 ~ 17kWh/t-material;

for coal grinding, power consumption may range between 20 ~ 22kWh/t-coal;

slag grinding, electricity consumption may range between 39 ~ 45kWh/t-slag.

The life-time of the wear resistant material is reported to vary between 8000 to 12000 hours. (NDRC,2008. p.50).

In China, market penetration of VRMs within the building materials sector was expected to reach 50% during the eleventh five-year development period, requiring an investment of around 1.08 billion RMB, and holding a potential to reduce energy consumption by 500 GWh (NDRC, p.51). 

VRMs are installed in new cement plants with dry systems, and also often replace ball mills during plant modernization, where the raw material moisture content is less than 25%. As of 2010, VRMs for raw material preparation had a penetration rate of 45% in Chinese market. During the twelfth five-year period, the market penetration of the technology is expected to reach 80% (MIIT, 2012. p.20)

Horizontal roller mills: Here materials are crushed inside of a rotating mill tube which also contains a grinding roller that is hydraulically pressed against the inside surface of the tube. Horizontal roller mills use 65-70% of the energy used in ball mills.

Roller press (high-pressure grinding rolls): In this technology materials are crushed between two counter-rotating rollers. These rollers are up to 2 m in diameter and 1.4 m long. Roller presses use 50-65% of the energy used in ball mills.

Vertical coal milll application and advantage

Vertical coal mill is typically designed to process materials in medium hardness, like soft coal or bituminous coal, and it is mainly used in positive pressure pulverizing system of soft coal.It is widely used in electricity field, metallurgy sector, building material industry, chemical industry, etc. It is an ideal device that integrates crushing, drying, grinding, and grading conveying all together.

　　Coal pulveriser design

　　In general, coal pulverisers are designed to achieve the maximum rated capacity grinding coal with a grind ability of 55 HGI and 8-12% moisture and achieving a discharge fineness of 70% passing a 200 mesh screen (74 micron) and 99.5% passing a 50 mesh screen. Variation of the coal hardness and moisture content will effect, up or down, the discharge capacity or the discharge fineness.

　　To achieve these design considerations it is essential that the grinding elements are in good condition and they maintain a consistent profile. The loss of the grinding profile results in a loss of grinding efficiency, meaning the pulveriser must work harder to achieve an equal result.

　　Ultimately a point will be reached in which either a loss of capacity or a loss of fineness will result under uniform conditions. Longer lasting, more consistent grinding elements are crucial to pulveriser operation yielding longer operating campaigns, reduced maintenance and a lower overall invested cost.

　　Environmental Friendly

　　With small vibration, low noise, and the overall sealing, the system works under negative pressure, so there is no dust going out. (It meets the requirements of the state environmental protection.)

　　High Drying Ability

　　As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with different humidity.

　　Simple and Reliable Operation

　　Firstly, it is equipped with automatic control systems, so remote control makes it easy to operate. Second, it is equipped with one device, which prevents the roller from contacting with the liner directly, and avoids the destructive impact and severe vibration.
