Nadu Mining offers its 0.074 – 0.60 mm (74 – 600 microns) raw perlite, a grade engineered to meet the demanding requirements of the construction and industrial sectors. Featuring a wide particle size distribution, this product combines fine particles that provide lightweight properties with medium-to-coarse particles that contribute to structural integrity. This characteristic makes it an indispensable raw material for applications where both strength and insulation are paramount.

When expanded, this raw perlite fraction forms an excellent aggregate structure, making it a reliable choice for a diverse range of fields. Its primary applications include:

• Construction Sector (Primary Application): It is the top choice for manufacturing lightweight building blocks, pre-blended insulating plasters, fireproofing coatings, cement-based screeds, and lightweight concrete. The broad particle distribution ensures both thermal/acoustic insulation and mechanical resistance in the final product.
• Agricultural Applications: Used to produce horticultural-grade perlite, which is ideal for soil conditioning and rooting media. The varied particle sizes achieved after expansion optimize soil drainage and aeration.
• Industrial Insulation: After expansion, it is effectively used to create loose-fill insulation materials for applications in masonry cavities, attics, and other void spaces.
• Metallurgy: This grade is a commonly chosen starting material for producing the expanded perlite used for slag collection and control in foundries.

Our 0.074 – 0.60 mm raw perlite undergoes rigorous quality control processes to provide a solution that is both economical and high-performance for your projects. Trust in the expertise of Nadu Mining to make a tangible difference in your construction and manufacturing endeavors.
