Energy Saving Limestone Vertical Roller Mill

Designed exclusively for power plant FGD systems, our energy-saving limestone vertical roller mill combines drying, grinding, classifying and conveying functions in a compact body. It delivers high-quality 325-mesh (44μm) limestone powder compliant with wet desulfurization standards.

Using this mill instead of traditional ball mills saves 30%-50% energy and 50% floor area, greatly lowering your overall costs. The hourly output ranges from 10 to 320 tons, with adjustable fineness between 80 and 325 mesh (180~44μm). It is an ideal, cost-efficient equipment for power plant desulfurization projects.

Core advantages:

1. Energy Saving

30-50% power cut, lower cost & carbon emission.

2. Integrated 5 Functions

All-in-one process, no extra dryer required.

3. Precision Grinding

Qualified powder for FGD, online fineness adjustment.

4. Easy Maintenance

Fast replacement of wear parts, less downtime.

5. Eco & Safe

Dust-free, low vibration & noise.

6. Stable Operation

PLC automation & remote monitoring available.

Working Principle of Vertical Mill

1. The motor drives the grinding disc to rotate via the reducer. Meanwhile, material falls from the feeding port to the center of the rotating grinding disc, and hot air enters the grinding chamber through the air inlet.

2. Under the action of centrifugal force, the material moves to the edge of the grinding disc. When it passes through the circular groove on the disc, it is crushed by the grinding roller.

3. The crushed material is picked up by the high-speed airflow at the edge of the grinding disc. Large particles directly fall back onto the disc for re-grinding.

4. The material carried by the airflow then passes through the dynamic-static separator. Under the action of the rotating rotor, coarse powder falls back to the grinding disc for re-grinding, while qualified fine powder is carried by the airflow.

5. The qualified fine powder is collected by the collecting device and becomes the final product.

6. For materials containing moisture, they are dried during contact with the hot air, ensuring the final product meets the required moisture content.

Applications

Power Plant Flue Gas Desulfurization (FGD)

Our vertical roller mill produces 325 mesh (44μm) limestone powder with 90% passing rate, the industry standard for wet FGD systems. The high-reactivity limestone powder effectively captures SO₂ from flue gas, ensuring compliance with emission regulations.

Circulating Fluidized Bed (CFB) Boiler Desulfurization

For CFB boilers that require coarser limestone powder (0.1-0.5mm), our mill can easily adjust output fineness to meet your specific requirements.

Other Applications

Metallurgical industry: flux production

Non-metallic mineral processing: calcium carbonate, talc, barite, gypsum

Building materials: cement, slag powder

Chemical industry: filler production

The vertical mill can process various materials including limestone, calcite, marble, dolomite, barite, talc, gypsum, bentonite, quartz, feldspar, bauxite, slag, and more

Case


Project Name: 20t/h Natural Gypsum Vertical Grinding Powder System Processing material type: natural gypsum or dolomite Production capacity: ≥ 20t/h Product fineness: 100 mesh, 90% -95% pass Production time: 2024
