Nadu Mining offers a wide product range to meet the needs of various industrial sectors. One of the most versatile products in this range is our 0.074 – 0.50 mm (74 – 500 microns) raw perlite, characterized by its unique blend of fine and medium-sized particles. This balanced particle size distribution allows for both controlled expansion and versatile application, making it an ideal raw material for numerous processes.

This fraction is in high demand because it enables the production of expanded perlite with diverse densities and pore structures. Its primary applications include:

• Construction Sector: It is a key component in the production of lightweight plasters, screeds, insulating concrete, and joint compound mortars. The broad particle range contributes to both excellent workability and a robust structure in the final product.
• Filtration: An excellent choice for filtration processes requiring medium to high flow rates. It provides effective clarity and an efficient filtering speed for the primary filtration of liquids such as beer, wine, oils, and chemical solutions.
• Cryogenic Applications: Ideal for producing the expanded perlite used to insulate double-walled cryogenic tanks that store liquefied industrial gases, such as LNG (Liquefied Natural Gas).
• Foundry Industry: It is preferred for manufacturing the expanded perlite used as a topping agent in metallurgy to cover molten metal, insulating it and preventing heat loss.

Our 0.074 – 0.50 mm raw perlite is engineered to enhance the efficiency of your production processes through its consistent quality and reliable performance. With the quality assurance of Nadu Mining, you can obtain the optimal solution for your most versatile projects.
