Product Description

second grade brown aluminium oxide grain

Production instruction

Here are the general instructions for producing brown aluminum oxide:

1. Raw material preparation: The main raw material for brown aluminum oxide is high-quality bauxite. The bauxite must be crushed and screened to ensure particle size and uniformity.
2. Mixing: Mix the bauxite with other additives to control color, hardness, and other properties.
3. Smelting: Add the mixture to an electric arc furnace and smelt it at high temperatures. During this process, the bauxite reacts with other additives to form brown aluminum oxide.
4. Cooling: Inject the molten brown aluminum oxide into a cooling pool to cool and solidify it quickly.
5. Grinding and screening: Grind the brown aluminum oxide into the desired particle size and screen it to ensure particle size and uniformity.
6. Packaging and storage: Package the brown aluminum oxide and store it in a dry, ventilated place to prevent moisture absorption and contamination.

These are general instructions for producing brown aluminum oxide, and the actual production process may vary depending on the manufacturer and product requirements.

TYPICAL APPLICATIONS:

Brown aluminum oxide has a variety of applications, here are some common application areas:

1. Grinding and polishing: Brown aluminum oxide is a hard and wear-resistant abrasive, widely used for grinding and polishing of materials such as metal, glass, and ceramics.
2. Surface treatment: The particle size and shape of brown aluminum oxide make it an ideal choice for surface treatment. It can be used for cleaning metal surfaces, removing oxide layers and other dirt, and increasing surface roughness.
3. Grinding wheel manufacturing: Brown aluminum oxide is one of the important raw materials for manufacturing grinding wheels, which can be used for grinding and polishing metals, wood, and other materials.
4. Sandblasting: Brown aluminum oxide can be used for sandblasting treatment, such as cleaning building surfaces, removing old coatings and dirt, etc.
5. Ceramic production: Brown aluminum oxide can be used for the production of ceramics, such as high-temperature ceramics, ceramic pigments, etc.

These are just some common application areas of brown aluminum oxide. In fact, it can also be used in many other fields, such as electronics, textiles, chemicals, etc.
