How to make desulfurization limestone powder? Desulfurization stone powder production and processing equipment

Desulfurization limestone powder is a kind of environmentally friendly and sustainable product, which is widely used in the desulfurization process of coal-fired power plants and other industries. Here's a step-by-step guide on how to make desulfurization limestone powder and the recommended equipment for the production and processing:

1. Crushing: The first step in producing desulfurization limestone powder is to crush the raw limestone into small particles. For this purpose, you can use a jaw crusher , hammer crusher, or impact crusher . The crushing process should be done in several stages to ensure that the particle size of the limestone is suitable for further processing.

2. Grinding: After crushing, the limestone particles need to be further ground into a powder. You can use a ball mill, Raymond mill, or vertical mill for this step. The grinding process should be controlled to ensure that the powder has a uniform particle size and meets the required specifications for desulfurization.

3. Classifying: The ground limestone powder is often classified into different particle sizes to meet the diverse needs of different applications. A particle classifier or air classifier can be used to separate the powder into different size fractions.

4. Calcining: In some cases, the limestone powder may need to be calcined to improve its desulfurization efficiency. Calcining refers to heating the limestone powder to a high temperature (usually between 800-1200°C) to convert it into a more reactive form. Calcination equipment such as rotary kilns or vertical shaft kilns can be used for this process.

5. Mixing and drying: Before being used for desulfurization, the limestone powder should be mixed with other ingredients such as activators and binders to improve its performance. After mixing, the powder mixture needs to be dried to remove any excess moisture. A dryer or rotary kiln can be used for this purpose.

6. Packaging and storage: The final desulfurization limestone powder should be packed in sealed bags or containers to prevent moisture absorption and ensure stability of the product. Store the powder in a dry and ventilated place to prevent moisture and contamination.

Recommended equipment for desulfurization stone powder production and processing:

1. Jaw crusher or hammer crusher for crushing limestone.

2. Ball mill, Raymond mill, or vertical mill for grinding limestone.

3. Particle classifier or air classifier for separating powder into different particle sizes.

4. Rotary kiln or vertical shaft kiln for calcining limestone powder.

5. Dryer or rotary kiln for drying the mixed powder mixture.

6. Sealed bags or containers for packaging and storing the final desulfurization limestone powder.

By following these steps and using the recommended equipment, you can successfully produce high-quality desulfurization limestone powder for use in various industries.
