Limestone Grinding Mill for Desulfurization

The current series of environmental protection policies is ongoing, focusing on the intensive implementation of policies to restrict production.
The relevant departments are expected to enhance their efforts to address prevailing environmental issues such as dust from desulfurization processes, which have led to severe pollution of the atmosphere, rivers, and other ecological environments.
The power plant enterprises will also face considerable pressure. With the escalation of environmental protection efforts, how will the power plant desulfurization industry develop?

For power plants, steel mills, and cement plants, the performance requirements for the desulfurization of limestone powder are crucial.
Introducing a high-performance desulfurization mill specifically designed for limestone - the new Raymond mill.
It incorporates several advanced technologies, boasts advanced production capacity, is easy to maintain, and can meet the desulfurization needs for processing limestone powder at 250 mesh, and 325 mesh.
Moreover, the equipment is equipped with an advanced dust collector, achieving a dust removal efficiency of over 99.99%, enabling virtually dust-free operation.




Desulfurization limestone powder production process:

1. Large limestone is crushed by the jaw crusher to the required size, and then sent to the storage hopper via the elevator.

2. Subsequently, the vibrating feeder uniformly, quantitatively, and continuously feeds the limestone into the grinding mill's chamber for processing.

3. The ground limestone powder is carried by the wind and classified through the powder separator.

4. The limestone powder that meets the required fineness enters the cyclone collector with the airflow through the pipe and gets separated and collected.

5. The collected limestone powder finished product is sent to the stone powder bin through the discharge port and conveyed for desulfurization.

6. Unqualified particles, once separated by the powder selector, are thrown against the cylinder wall, fall along it, and then return to the mill for further grinding.

7. The entire system operates under negative pressure, preventing dust from overflowing and ensuring the cleanliness of the site.



Limestone-gypsum wet desulfurization process first requires the production of a desulfurization agent. The desulfurization agent is typically composed of limestone powder, with the quality and fineness of the limestone powder (250 mesh or 325 mesh limestone powder is ideal for desulfurization) and particle distribution being key factors that affect the desulfurization effectiveness.

Therefore, the selection of the appropriate limestone powder preparation process and equipment is crucial for the entire desulfurization process.
Under the pressure of environmental protection policies, eco-friendly mills are primarily utilized in the desulfurization processes of large power plants and steel mills.
This aligns with the principles of environmentally friendly production and presents promising market prospects.
