Product Description
Product profile 

The expanded perlite is one kind of white granule with Honeycomb structure inside and it is produced when Perlite ore Preheated and Instantaneous high temperature roasted. The Principle is that expanded perlite is crushed by the ore, dealed with the rapid heating (***0ºC above). After the moisture vaporization ores and minerals in the particles soften internal expansion, the formation of porous structure, expansion to the original ****0 times.It is divided into two types according to expansion technology and usage and they are open cell and closed cell.

The closed surfase perlite produced by the perlite expansion furnace , also know as glassy microsphere, is the precise control of the temperature and the time of the raw material in the expansion furnace . The product surface is melted , the air hole is closed , the spherical body is fine particles , the internal porous cavity structure , the surface is closed ,the gloss is smooth , the physical and chemical properties are stable , and the quality is high .Light ,thermal insulation ,thermal insulation , fire protection , high and low temperature resistance, anti-aging , small water absorption and other excellent characteristics , is an environmentally friendly high-performance inorganic light thermal insulation material. 



Working Principle
China expansion perlite furnace supplier with CE/ISO/SGS certificates
The production process of expanded perlite includes two key processes of preheating and expansion.

(1) Preheating: According to the difference of origin and grain size, after the pearlite ore is preheated for **8 minutes at a temperature of ******0 °C, the water content will reach the expansion requirement.

(2) Expansion: The pre-heated ore is evenly sprinkled onto the flame at a temperature of ********0 °C through the feeding device. The ore will be heated rapidly and rapidly expand to ****0 times the original volume. The expanded perlite The particles are white or light gray and contain a honeycomb structure inside.

(3) The expanded perlite enters the collection bin with the high-temperature gas separated by the cyclone separator, and the high-temperature gas containing a small amount of fine dust is discharged to the atmosphere by the bag dust removal device.
