Sodium Bicarbonate Powder Grinding
Daswell sodium bicarbonate grinding line provides ultrafine powder preparation for dry FGD and DSI systems. It features precise particle size control, high reactivity, stable operation, and direct integration with flue gas treatment processes.
Sodium bicarbonate (NaHCO₃) is also known as bicarbonate of soda. It is an important alkaline material, which is widely used in sodium bicarbonate dry sorbent injection (SDS) systems and dry flue gas desulfurization (Dry FGD) applications. It is one of the most effective dry sorbents for industrial flue gas treatment. You can use it for removing acidic pollutants such as sulfur dioxide (SO₂), hydrogen chloride (HCl), hydrogen fluoride (HF), and sulfur trioxide (SO₃).
For improving the reaction efficiency with acidic gases, the sodium bicarbonate needs to be processed into fine powder with controlled particle size, high specific surface area, and excellent reactivity. Finer particles provide a much larger reaction surface, enabling faster neutralization of acidic gases while reducing sorbent consumption.
Daswell Powder sodium bicarbonate powder grinding line is designed for industrial air pollution control. This grinding line utilizes advanced ultrafine grinding technology. It mainly adopts a horizontal ultrafine grinding mill, which integrates grinding and air classification in one compact system. It is applicable for you to adjust the classifier wheel speed and get your required particle size precisely. With our sodium bicarbonate powder grinding line, you can get uniform powders with high grinding efficiency in less space.
Sodium Bicarbonate Powder Grinding Process
For sodium bicarbonate powder preparation, Daswell Powder adopts a horizontal air classifying mill as the core equipment of the sodium bicarbonate grinding system. The whole grinding line includes feeding, grinding, and air classification, and direct pneumatic conveying to the flue gas injection system. With this set of grinding line, you can produce sodium bicarbonate powder with the required particle size and high reactivity for your efficient acid gas removal.
Raw Material Feeding
There is a controlled feeding system for feeding sodium bicarbonate raw materials into the horizontal grinding mill evenly. The stable feeding ensure the consistency of final powder quality.
Powder Grinding and Air Classification
When the sodium bicarbonate material enters the grinding chamber, sodium bicarbonate particles are rapidly reduced by high-speed impact and shear forces. The ground fine powders are separated by the built-in classifier wheel. The coarse particles are automatically returned to the grinding zone for further grinding. You can adjust the rotation speed of the classifier wheel to control particle size. This integrated grinding and classification design helps achieve a narrow particle size distribution and stable product quality.

Direct Pneumatic Conveying
The qualified sodium bicarbonate powder is pneumatically conveyed directly to the injection lances of the DSI systems. The ultrafine powder is injected into the flue gas duct. Then the sodium bicarbonate is thermally activated in the high-temperature flue gas and quickly reacts with acidic pollutants such as SO₂, HCl, HF, and SO₃, achieving highly efficient flue gas purification while minimizing sorbent consumption.
This sodium bicarbonate grinding system features low dust emission, high automation, and stable operation. It provides a reliable supply of fine sodium bicarbonate powder for direct integration with DSI systems and efficient industrial flue gas treatment. If you are planning to establish your own sodium bicarbonate powder grinding line for your plant, send an inquiry to us. We can design for you.
