Vertical Coal Mill 20 T/H 200 Mesh 100% Passing Rate Coal Mill Used In Power Plants ,Steel Plants
Product Introduction:
HVM series vertical coal mill
The HVM series vertical coal mill is a new type of grinding equipment that has undergone multiple improvements and optimizations, reaching international standards and providing users with reliable coal powder preparation solutions.
Integrated process for coal powder preparation
The uniqueness of the HVM series vertical coal mill lies in its dual operation of drying and powder making. This means that while grinding coal, the coal powder can also be dried. The innovation of this process not only improves production efficiency, but also reduces energy consumption, bringing significant energy-saving and environmental benefits to users.

Technical Specifications
The HVM series vertical coal mill is suitable for users with high requirements for coal powder production, and its preparation range for coal powder processing is 5-100T/H. This means that it can meet the needs of power plants of different scales and industrial production, providing users with greater flexibility and choice space.

System security and stability
The system design of HVM series vertical coal mills emphasizes safety and stability. Its operation is safe and reliable, with low noise, providing better comfort for the working environment, while reducing the cost of equipment maintenance and repair. The stability of the system ensures long-term efficient operation.

Parameter Table of Coal Vertical Mill

Technical advantages and characteristics
(1) High grinding efficiency
Grinding efficiency is high, energy consumption is low, and compared to ball milling, energy consumption is 40-50% lower. It has a large single machine production capacity and can utilize low valley electricity.
(2) High degree of automation
Adopting a PLC fully automatic control system and capable of remote control, it is easy to operate, easy to maintain, and reduces labor costs.
(3) Stable product quality
The material stays in the grinding machine for a short time, reducing repeated grinding. The product has a uniform particle shape, narrow particle size distribution, good fluidity, strong adaptability, and a very low iron content, high whiteness and purity.
(4) Low operation and maintenance costs
The grinding roller can be flipped out of the machine using a hydraulic device, making maintenance operations convenient. The grinding roller sleeve can be flipped over for use, extending the service life of wear-resistant materials with low wear. The lining plates of the grinding roller and grinding disc are made of special materials, which have a long service life.
(5) Low noise environmental protection
The entire system has low vibration and low noise. It adopts an overall sealed negative pressure operation system, an air box pulse dust removal system, and no dust overflow, basically achieving a dust-free workshop.
(6) Strong drying ability
Directly blowing hot air, the hot air comes into direct contact with the material inside the mill, with strong drying ability. The maximum moisture content of the feed can reach 15%, without the need for an additional dryer, saving equipment investment and energy consumption costs.
(7) High reliability
Adopting a grinding roller limiting device to avoid severe vibration caused by material breakage in the mill, a new type of grinding roller sealing device is adopted, which is reliable and does not require a sealing fan, further reducing the oxygen content in the mill and achieving excellent explosion suppression performance.
(8) Low comprehensive investment cost
Integrating crushing, drying, grinding, grading, and conveying, the process flow is simple, the structural layout is compact, and the land area is small, only 50% of that of ball milling. It can be arranged outdoors, with low construction costs, directly reducing investment costs.
