Energy Saving Environmentally Friendly Vertical Mill Coal Mill Roller Mill Lime Vertical Mill
Product Introduction:
Vertical mill, also known as roller mill, is widely used in large-scale material grinding and ultra-fine powder processing in industries such as cement chemical, coal, and power. It is an ideal equipment in the grinding industry that integrates crushing, drying, grinding, grading, and conveying. When used for coal powder preparation, it can make the product fineness meet industry standards.

Highlighting advantages
*High grinding efficiency and low power consumption
*Simple and reliable operation, stable product quality
*The process flow is simple, and the functions of grinding, drying, and powder selection are completed simultaneously
*Small footprint, compact layout, and low investment in civil construction

Operational principle
In the process of coal powder production, the main motor drives the grinding disc to rotate through the reducer, while hot air enters the vertical mill body from the air inlet. The raw coal falls to the center of the grinding disc through the feeding pipe, and the constant speed rotating grinding disc disperses and flattens the raw coal outward with the help of centrifugal force, forming a certain thickness of material bed. The raw coal is simultaneously crushed by multiple grinding rollers on the grinding disc. Under the continuous drive of centrifugal force, the raw coal continuously moves towards the outer edge of the grinding plate. When the powder leaving the grinding plate meets the hot gas entering the mill through the wind ring and rises, it enters the separator through the middle shell of the mill. During this process, the coal powder and the hot gas have sufficient heat exchange, and the water is quickly evaporated. The powder selection machine controls the particle size of the finished product at the outlet of the roller mill. Particles larger than the specified size are separated and fall back to the grinding disc. Coal powder that meets the fineness requirements enters the dust collector through the powder selection machine, and the collected finished product is sent to the finished product warehouse.

Advantages of coal vertical mill

1. High energy efficiency

Due to the reasonable fluidization structure, good material fluidization state, and significantly lower gas consumption compared to similar products, our company has made multiple improvements to the fluidization structure after years of production and research, greatly improving production efficiency and reducing energy consumption.

2. High material to gas ratio

Good fluidization effect, low gas consumption, and higher material to gas ratio. Through laboratory testing, the equivalent distance is within 500 meters, and the material to gas ratio reaches over 30Kg (ash)/Kg (gas).

3. Low material flow rate

Due to low air consumption and high material to gas ratio, the material moves in a partial flow in the pipeline, achieving dynamic and static pressure transportation. Therefore, the flow rate during material transportation is low, the wear of equipment valves and pipelines is small, and the service life of vulnerable parts is long.

4. Strong adjustment function

Equipped with various adjustment methods such as primary and secondary air intake regulation, the system can operate under the optimal air consumption ratio and excellent fluidization state.

5. Unique blockage removal method

Our company adopts a reverse suction blockage removal method, which is simple, easy to operate, and operates reasonably. We only need to introduce the material and gas mixture to the silo or flue inlet through the blockage removal valve and pipeline.

6. Easy to solve supporting facilities

Due to its low gas consumption and low speed, the material and gas separation and filtration equipment in the silo can be smaller than those equipped with general silo pumps, resulting in less air pollution.

7. Low energy consumption coefficient

The energy consumption coefficient of our warehouse pump conveying system is below 65KW. h/t. m.

8. High degree of automation

The programmable logic controller (PLC) control system is adopted, and the entire working process can be fully automated. The system can be set to automatic or manual operation mode. The main control cabinet is installed in the system control room.
