Vertical Coal Mill - High Efficiency Grinding for Power Plants & Cement Industry

Product Descripition:

Highlights of vertical coal mill products
1, Efficient and energy-saving
1. Efficient grinding principle: Advanced material layer grinding principle is adopted, and the material forms a material layer between the grinding disc and the grinding roller for rolling and crushing. Compared to traditional ball mills, this method has a higher energy utilization rate and can reduce the power consumption of the grinding system by 20-30%. For example, when dealing with coal powder production tasks of the same scale, if the power consumption of the ball mill is 100 degrees, the vertical coal mill only needs 70-80 degrees, greatly saving electricity costs.
2. Optimization of Grinding Roller Design: The grinding roller adopts a special structural design, and the roller sleeve can be flipped over for use, greatly extending the service life of the grinding roller. In the long-term use process, when one side of the roller sleeve wears out to a certain extent, it can be flipped over by simple operation and continued to be put into use, reducing the cost and downtime of frequent replacement of grinding rollers and improving production efficiency.
3. Efficient transmission system: Equipped with high-performance reducers and motors, the transmission efficiency is high and the power transmission is stable, ensuring that the mill operates efficiently while reducing energy consumption.

2, Strong drying ability
1. Fully utilize hot air: The mill adopts a drying method where hot air directly contacts the material, resulting in high heat exchange efficiency. By adjusting the temperature and flow rate of the hot air reasonably, materials with high moisture content can be effectively dried, and the materials can be dried synchronously during the grinding process. The final product moisture can meet strict requirements. For example, for raw coal with a moisture content of up to 15%, after being processed by a vertical coal mill, the moisture content can be reduced to below 1%, meeting the coal powder usage standards.
2. Wide drying range: Whether it is high-quality coal with low moisture content or lignite with high moisture content, it can be efficiently dried and ground to meet the processing needs of different types of coal, providing users with a wider range of raw material choices.

3, Stable product quality
1. * * Short residence time of materials * *: The residence time of materials in the mill is relatively short, usually only 2-3 minutes. This enables rapid determination and calibration of the chemical composition and fineness of the product. Once deviations occur, process parameters can be adjusted in a timely manner to ensure the stability of product quality.
2. * * Precision grading system * *: Equipped with an efficient separator, it can accurately grade coal powder to ensure uniform particle size of the finished coal powder. By adjusting parameters such as the speed and blade angle of the separator, the fineness of the product can be flexibly controlled to meet the diverse needs of different users for coal powder particle size.

4, Reliable operation, easy operation and maintenance
1. Reliable lubrication system: Equipped with a thin oil lubrication station, the grinding roller bearings adopt concentrated circulation lubrication of thin oil to ensure that the bearings work under low temperature and pure oil conditions, greatly extending the service life of the bearings and ensuring the continuous and reliable operation of the equipment operating system.
2. Advanced Automatic Control: Equipped with advanced automatic control devices, it can achieve remote control. Operators only need to monitor and adjust the real-time operation status of the grinder in the control room, which is simple and convenient to operate, reduces labor intensity, and improves production safety.
3. * * Convenient and fast maintenance * *: The hydraulic station system is equipped with maintenance oil cylinders and flipping arms, which can achieve automatic roller lifting and falling functions. When replacing vulnerable parts such as roller sleeves and lining plates, there is no need for complex disassembly work, greatly reducing maintenance time and minimizing downtime losses.

5, Superior environmental performance
1. * * Low noise * *: During operation, the grinding roller and grinding disc do not come into direct contact, reducing the noise generated by friction. The noise level is 20-25 decibels lower than that of the ball mill, effectively reducing noise pollution to the surrounding environment and providing a more comfortable working environment for operators.
2. * * Less dust * *: The entire system is fully sealed and operates under negative pressure, with no dust spillage. Even on the production site, there is almost no obvious dust flying, effectively reducing the pollution of dust to the environment, complying with strict national environmental standards, and helping enterprises achieve green production.

Working Principle:
The material falls into the center of the grinding disc through the feeding tube, and the grinding disc rotating at a constant speed uses centrifugal force to evenly disperse and flatten the material outward, forming a certain thickness of material bed. Under the drive of the grinding disc, the material is pushed onto the roller conveyor of the grinding device and crushed by the rolling of the grinding roller. Under the action of centrifugal force, the pulverized coal powder overflows from the edge of the grinding disc and is carried by the high-speed upward hot air flow from the nozzle ring (air ring). Large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the upper separator, the coarse powder will return to the grinding disc for grinding under the action of the rotating rotor, and the qualified fine powder will enter the dust collector with the airflow and be collected into products.
