Vitrified micro production process:

The ore mined from the mine is processed into ore with particle size gradation through mechanical crushing and vibrating screening, and the expansion plant is purchased according to different uses. The water content of perlite raw ore is generally 4-6%, due to the high water content, after high temperature heating, the rapid volatilization of water will cause the explosion of perlite. Therefore, the ineffective water content of perlite should be removed before expansion first, so that it retains the water required for normal expansion (i.e., effective water).

After a large number of experiments in laboratories and production plants at home and abroad, it is concluded that when the effective water content of expanded perlite is in between, the effect after expansion is good, and the expansion multiple is large (i.e., the loose density is small). Therefore, the production process of expanded perlite should include two key processes: preheating and expansion.

1. Preheating: According to the different origins and particle sizes, after preheating the perlite ore at a temperature of 250-400 for 2-8 minutes, the moisture content of preheating and dedrying will meet the expansion requirements.

2. Expansion: After preheating, the ore will be evenly sprinkled to the flame with a temperature of 900-1200 to keep the temperature at 900-1200 high temperature by the feeding device, and the ore will be heated sharply and rapidly expanded to 10-30 times the original volume, and the expanded perlite particles are white or light gray, containing a honeycomb structure inside, and the loose density is generally 40-80kg m3.

3. The expanded perlite enters the aggregate bin with the high-temperature gas through the cyclone separator.
