Energy-Saving Vertical Coal Mill with Coal Grinding Mill Advanced Technology

High Efficiency and Energy Saving Vertical Coal Mill: Vertical Mill Drastically Cut Energy Costs

Product Descripition:
Vertical coal mill, also known as coal mill or coal vertical mill, is an energy-saving coal powder production equipment suitable for grinding medium hardness materials such as raw coal and bituminous coal. It can be widely used in powder production systems in industries such as power, metallurgy, building materials, and chemical engineering.

【 Application Fields 】
Industries such as building materials, chemicals, metallurgy, electricity, and coal powder preparation.
[Applicable Materials]
Bituminous coal, smokeless coal, lignite, etc.

Coal Pulverizer 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.

Parameter Table of Vertical Coal Pulverizer

Physical Property
Compact structure: The overall structure is relatively compact, occupying a relatively small area, which can effectively save installation space and facilitate layout in different sites.
Durable Material: Usually made of wear-resistant and corrosion-resistant metal materials, key components such as grinding rollers and grinding discs are often made of special alloy steel to withstand high pressure and friction, extending their service life.
Performance attributes
High grinding efficiency: By utilizing the relative motion between the grinding roller and the grinding disc to compact and grind the material, block shaped materials can be quickly ground into fine powder, which can effectively improve production efficiency compared to traditional grinding equipment.
Strong drying ability

It can introduce hot air to dry materials and can handle materials with high moisture content. Generally, it can reduce the moisture content of materials to about 1% -2%, meeting the requirements of different production processes for material moisture.
High product accuracy

Equipped with an efficient powder selection device, it can accurately control the particle size distribution of the product, making the finished product particle size uniform, and can produce products with different fineness requirements, such as controlling the coal powder fineness within the R90 sieve residue range of 3% -12%.
Run Properties
Low energy consumption

By using the material bed grinding principle, compared to traditional grinding equipment such as ball mills, the energy consumption can be reduced by about 30% -50% when grinding the same amount of material, which has significant energy-saving advantages.
Low noise

The noise generated during operation is relatively low, generally below 85 decibels, which is beneficial for improving the working environment and reducing noise pollution.
Easy maintenance

The structure is relatively simple, and components such as grinding rollers and grinding discs are easy to disassemble and replace. Daily maintenance and repair work is relatively convenient, which can effectively reduce maintenance costs and downtime.
