Nadu Mining provides its precision-classified raw perlite products for applications that demand a high degree of engineering. Our product in the 0.30 – 0.60 mm (300 – 600 microns) range features a narrow and homogeneous particle distribution, achieved by completely screening out all fine particles. This highly classified structure yields a raw material that is essentially dust-free, exhibits excellent flowability, and has extremely consistent expansion characteristics.

This perlite fraction is specifically engineered for technical applications where absolute homogeneity and predictable performance in the final product are critical. Its primary applications include:

• High-Performance Construction Materials: When expanded, it forms an ideal aggregate for sound-absorbing acoustic panels, decorative textured plasters, and lightweight concrete panels requiring uniform density. The consistent particle size ensures an aesthetic and homogeneous surface finish.
• Foundry and Metallurgy: It is the primary choice for producing materials used in risering and ladle topping compounds, which form a homogeneous insulating layer on molten metal. Its consistent expansion helps to precisely control the metal’s cooling rate.
• Filtration Systems: After expansion, it is used to create a highly permeable filter bed for high-flow-rate industrial processes, such as filtering viscous liquids or dewatering sludge.
• Chemical Carrier: The uniform pore structure of its expanded form makes it an ideal carrier for active chemicals like pesticides and herbicides, enabling their controlled release.

Our 0.30 – 0.60 mm raw perlite is a specialized solution from Nadu Mining for projects where technical specifications and reliability are the highest priorities.
