Mineral Wool Rock Wool Blanket Production

Mineral wool, also known as rock wool, is a type of insulation material made from natural minerals such as basalt or diabase. 

The production process of mineral wool rock wool blankets involves several steps:

1. Raw Material Preparation: Basalt or diabase rocks are crushed into small pieces and then heated to a high temperature in a furnace.

2. Melting: The heated rocks are melted at a temperature of around 1500°C to form molten lava.

3. Fiber Formation: The molten lava is then spun into fibers using a spinning wheel or a centrifugal spinning process. The fibers are blown with a stream of air to create a wool-like material.

4. Binding: A small amount of binder is added to the fibers to improve their cohesion and strength.

5. Curing: The fibers are cured in an oven to harden the binder and ensure the stability of the material.

6. Cutting and Shaping: The cured mineral wool is cut into desired sizes and shapes, such as blankets, rolls, or boards.

7. Packaging: The finished mineral wool rock wool blankets are packaged and prepared for distribution.

It’s important to note that the production process may vary slightly depending on the specific manufacturer and the desired properties of the final product.
