For many mill scale fines owners, traders, or users, if you have many tons of mill scale fines but don't know how to create additional values to them, please read this article. It may provide you some inspiration.

1. Definition:

Mill scale fines: Mill scale fines?are iron ore powder produced by high temperature oxidation reaction during steel production. These powders are generally small iron oxide particles, mainly composed of iron oxide, and are commonly found in the rolling and cooling process of steel mills.

Mill scale briquettes: Mill scale briquettes?are iron scale powders that have been processed into larger particle agglomerates through pressing or other processes. In this way, the morphology of the powder is changed, making it suitable for further smelting or other industrial applications.

2. Features:

Mill scale fines:

- Small particle size, easy to pile up, resulting in transportation and storage difficulties.

- Contains a large amount of unused iron components, with potential high added value.

- Has a high iron oxide content, suitable for recycling or other chemical reactions.

Mill scale briquettes:

- After agglomeration, the volume is larger, which is convenient for handling and transportation.

- Agglomeration increases the density of the powder, making it more stable in blast furnace smelting.

- It can reduce dust pollution and improve the uniformity of the charge.

3. Application:

Mill scale fines:

- As an auxiliary material in the steel smelting process, it provides an efficient iron source.

- Used to produce recycled iron and other ferroalloys.

- Can be used to make iron oxide pigments in the construction, chemical and other industries.

Mill scale briquettes:

- Can be used as a raw material directly used in the smelting process to improve the utilization efficiency of iron ore.

- In steel plants, it is used as a substitute raw material for blast furnace or electric furnace smelting.

- Suitable for industrial use in other metal extraction and refining.

4. Advantages:

Mill scale fines:

- Can be used directly in blast furnace smelting to provide an efficient iron source.

- Due to the small particle size, it can be better mixed with other raw materials to promote the uniformity of the smelting process.

- Compared with untreated iron oxide scale, it has a higher iron content and higher utilization efficiency.

?

Mill scale briquettes:

- The agglomeration process reduces the volatility of Mill scale fines?and reduces dust pollution.

- Enhances the operability of iron oxide scale, making it easier to store, transport and use.

- The density and firmness of the agglomerates make them more stable during the smelting process and can effectively improve the utilization rate of the charge.

5. Preparation:

The following equipment and steps are usually required to manufacture scale agglomerates:

- Powder processing: First, the scale fine powder needs to be screened, cleaned and other pre-processed.

Binder selection: It is necessary to select a suitable binder to ensure that the scale powder does not disperse during the pressing process. Commonly used binders include natural clay, starch or chemical binders.

Pressing equipment: The fine powder is pressed into agglomerates using cold or hot pressing equipment. Common equipment includes double-roll briquetting machines, vertical presses, etc.

Drying: After the agglomerates are manufactured, they need to be dried by drying equipment to improve the strength and durability of the agglomerates.

6. Who will need?the mill scale?briquettes?

Steel mills: Mill scale briquettes?are needed as alternative raw materials for smelting, especially in blast furnaces and electric furnaces.

Metal refineries: Mill scale fines?needs to be processed and converted into metal raw materials that can be directly used.

Environmental treatment industry: Mill scale briquettes?reduce dust during the treatment process and can effectively reduce environmental pollution.

7. How should I start this business?

1. Market research: understand the demand for Mill scale briquettes?in your area and identify potential customers.

2. Site selection and equipment investment: select a suitable site and purchase relevant equipment such as pressing and drying according to the annual output demand.

3. Raw material procurement: Ensure a stable source of Mill scale fines?and suitable binders.

4. Determination of production process: Establish a production line that meets production standards to ensure the stable quality of briquettes.

5. Operation and management: Establish an effective supply chain management and quality control system to ensure a stable supply of products.

8. Why do I write this article?

As a manufacturer of Binder for the production of mill scale?briquettes, we hope to provide the industry with relevant information about Mill scale fines?and briquettes to help customers understand how to improve the value and utilization efficiency of mill scale fines?through agglomeration. At the same time, as a manufacturer, we also hope to demonstrate our expertise in the field of binder production to help more companies improve production efficiency and reduce environmental pollution.
