ENIVO Perlite Expansion Plants are designed to expand raw perlite through a controlled heat process, transforming it into a lightweight, low-density, and high-performance product. By precisely managing temperature, residence time, and material flow throughout the process, consistent product quality can be achieved for building materials, insulation products, agricultural applications, and industrial uses.
Perlite expansion is not simply a heating process. The density, particle structure, volumetric yield, and suitability of the final product for its intended use depend on the correct matching of raw material characteristics with process parameters. For this reason, ENIVO approaches each project individually, based on raw material properties, target product characteristics, and capacity requirements.





Raw perlite is fed into the expansion unit in a controlled manner and rapidly increases in volume as the bound water within the material vaporizes under high temperature.
Through this expansion, the material reaches a lightweight, porous, and high-volume structure. In order to operate the process efficiently, temperature level, residence time inside the furnace, and airflow must be managed in a balanced manner.
The particle size distribution, density, and physical structure of the final product depend not only on furnace performance, but also on the feeding system, separation systems, and the downstream conveying, storage, or filling stages.
ENIVO approaches perlite expansion plants not as a single machine, but as a fully integrated process line in which all components work in harmony.





Depending on project requirements, ENIVO Perlite Expansion Plants can be configured to include the following process stages:
This integrated approach contributes not only to the expansion process itself, but also to the more stable, efficient, and controlled operation of the entire line.
In perlite production, the correct process design must be determined according to the structure of the raw perlite and the characteristics of the desired final product. Different perlite sources may vary in terms of particle structure, moisture behavior, expansion potential, and bulk density results. Likewise, the required perlite properties may vary depending on the intended application, such as construction chemicals, lightweight plasters, insulation products, agriculture, or industrial uses. For this reason, ENIVO adopts an engineering approach focused not only on capacity, but also on the end product itself. The aim is to ensure that each plant can produce product characteristics suitable for its target market and application.
ENIVO approaches perlite expansion plants not merely as furnace systems, but as integrated production solutions extending from raw material to final product. This approach enables:
ENIVO Perlite Expansion Plants provide long-lasting, efficient, and reliable production solutions through the right process approach, proper equipment selection, and integrated plant engineering.
