Coal and Anthracite Pulverizer

-- Steady & Reliable Manufacturer --

Introduction

Pulverized coal is the primary fuel for the majority of the world's thermal power plants and is also used in industries like cement and steel. Our coal and anthracite pulverizers are engineered for safety, efficiency, and reliability. They are designed to grind raw coal into a fine powder (known as pulverized fuel or "PF") with a consistent particle size, which is essential for ensuring complete and efficient combustion in the boiler. With integrated drying capabilities and advanced safety features, our mills are the heart of a clean and efficient coal combustion system.

Applications

  • Power Generation: Firing pulverized fuel in thermal power plant boilers to generate steam.
  • Cement Kilns: Used as the primary fuel source for heating cement kilns.
  • Steel Mills: Pulverized Coal Injection (PCI) into blast furnaces to reduce coke consumption.
  • Lime Kilns: Fueling industrial lime production.

Advantages

  • Intrinsic Safety: Our vertical roller mills are designed with safety as a priority, featuring low oxygen operation, integrated inert gas systems (CO₂), and explosion-proof vents to safely handle combustible coal dust.
  • High Drying Efficiency: Can effectively use hot primary air or waste gas to dry high-moisture coal during the grinding process, saving on pre-drying costs.
  • Excellent Fineness Control: The dynamic classifier provides precise control over the particle size, ensuring optimal combustion and minimizing unburnt carbon.
  • High Availability: Designed for continuous operation with features for rapid online maintenance of wear parts.

Payment & Shipping

For critical energy infrastructure projects, we offer structured payment terms, including T/T and Bank Guarantee / L/C. Our logistics team is expert in managing large-scale, multi-modal shipments to remote project sites, ensuring all components arrive securely and according to the project schedule.

Frequently Asked Questions

  • Q: How do you prevent explosions in a coal pulverizer?
  • A: We use a multi-layered safety approach: 1) Temperature and CO monitoring to detect early signs of combustion. 2) Operating under a low-oxygen atmosphere. 3) An inert gas (like CO₂) injection system to extinguish any potential fire. 4) Explosion-proof relief vents to safely direct the pressure from a deflagration.
  • Q: Can your mill handle different types of coal, like bituminous and anthracite?
  • A: Yes. The mill's grinding pressure and classifier speed are adjustable. We can set the optimal parameters based on the coal's Hardgrove Grindability Index (HGI) to efficiently process everything from softer bituminous coal to harder anthracite.
