Cutting Edge Technology

Silbrico Perlite expanding systems are accepted as the standard by most major perlite producers in the world. We’ve been producing these systems in our facility since 1964 and are constantly innovating to provide the best possible products. Because we are experts at manufacturing perlite, we know how to design to your specific needs. From expanders to conveying equipment to lab testing equipment, Silbrico has you covered.

Plant Perlite Expanders

Silbrico Perlite Expanding Systems produce high-quality perlite, require low maintenance, and are highly versatile. They have been developed to meet Silbrico’s own demanding perlite manufacturing needs. Silbrico customers, both manufacturers and end-users, use these expanders to produce diversified aggregates for use in plaster, concrete, acoustic tiles, refractories, soil-conditioners, filter aid, and more.

Portable Perlite Expanders

This system is specially designed for producing light-density cryogenic perlite insulation. A modular system that is quickly assembled and disassembled, it is stored in a 40-foot, open-top container. It includes all components necessary to expand properly sized perlite ore, separate the expanded perlite from the exhaust gasses, and convey the perlite into the vessel to be insulated. The exhaust gasses are bag filtered to meet all environmental regulations.

Laboratory Perlite Expanders

Whether you’re purchasing, mining, or manufacturing, knowing the quality of the ore is crucial. These expanders allow for the expansion of small quantities of perlite ore in a controlled environment, so that you can test for many properties of perlite ore, including expansion coefficient, loose density, compact density, post-expansion chemical composition, and more!

Conveying Equipment

We develop this equipment for our own perlite conveying needs and they have consistently proven to gently and efficiently convey perlite without breaking down the particles. Whether you need conveying equipment to unload rail cars of raw ore or gently convey fragile expanded materials, Silbrico can custom design to fit virtually any production need. We offer Perlite Weight Transporters, Twin Transfer Chambers, Twin 10” Conveying Pumps, and more.

Laboratory Testing Equipment

This equipment assists in the production of perlite filter-aid by creating an “as-used” environment, allowing you to test your products as they are being produced as a means of quality control. Silbrico’s Pressure Flow-Rate Tester is used to determine flow rates of filter-aids, simulating pressure filter application. Silbrico’s CRC II Tester is used to determine flow rate and wet density of filter-aids, in accordance with Perlite Institute PI 501-83 test method.
