Product Details Company Profile
Product Details
The vertical coal mill (also known as vertical coal pulverizer or roller coal mill) is a highly efficient equipment specifically designed for coal grinding, which is widely used in the coal powder preparation systems of industries such as power generation, metallurgy, and building materials. The following are its main attributes and characteristics:
Basic Structure
Grinding Table: A horizontally rotating circular plate on which materials are crushed and ground.
Grinding Rollers: Usually 2 to 4, symmetrically arranged, applying pressure to the materials through a hydraulic or spring system.
Separator: A dynamic or static powder selection device that controls the fineness of the finished coal powder.
Transmission Device: The motor and reducer drive the grinding table to rotate.
Shell and Seal: Prevent the leakage of coal powder and ensure the safety of the system (with explosion-proof design).
Core Attributes
Processing Capacity: 5 to 200 tons per hour (depending on the model).
Feed Particle Size: ≤ 50mm (pre-crushing required).
Fineness of the Finished Product: The remaining amount on an 80μm sieve is adjustable (usually R90 = 8% to 20%).
Moisture Adaptability: It can process raw coal with a water content of ≤ 15% (hot air drying is required).
Technical Advantages
High Efficiency and Energy Saving: Adopt layer grinding, resulting in low energy consumption.
Small Floor Space: With a vertical structure, it has a high space utilization rate.
Flexible Adjustment: Adjust the roller pressure, air volume, and powder selection rotation speed online.
Good Environmental Protection: It is a fully enclosed system with less dust leakage.

Re:Raw materials bond index≤13kWh/t


Typical application scenarios
Thermal power plant: preparing coal powder for boiler injection.
Cement plant: Coal powder combustion is used for rotary kilns.
Steel plant: Blast furnace coal injection system.


Precautions
Explosion proof requirements: Explosion proof valves, CO/O ₂ monitoring, and inert gas protection must be equipped.
Wear resistant component lifespan: The lifespan of the grinding roller/disc liner is approximately 8000-12000 hours (depending on the coal quality).
Maintenance focus: Regularly inspect the roller sleeve, seal, and hydraulic system.

If more specific parameters are needed (such as power, size, etc. of a certain model), further requirements or application scenarios can be provided for precise matching.
