PAXAA provide full range perlite processing plant covering ore size reduction & classifying and perlite expansion plant to produce light weight open cell expanded perlite. Perlite is a glassy volcanic rock with a pearl-like luster. It usually exhibits numerous concentric cracks that cause it to resemble an onion skin.
Perlite Expansion Furnace Plant 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.
The expert testimony developed that the Gladney patent teaches a two step process for the expansion of pumicite, another volcanic glass, that the patent purports to relate to cellular stones, that perlite is a cellular stone, "that the preheating of both perlite and pumicite is done for the same reason, to prevent shattering in the second step."
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 2-8 minutes at a temperature of 650-800 °C, the water content will reach the expansion requirement.
Perlite Preheating Furnace. Perlite Preheating Furnace is used to produce high-quality perlite vitrified microbeads, perlite ore for preheating drying.
Government awarded the perlite mining rights to our factory in 2004, at that time we only sell raw perlite sand. In the year of 2008 we have perlite slag remover factory, we built two set perlite preheating furnace to produce perlite slag remover.
perlite crushing crusher - rajpmscoin Perlite Expanded Processing Plant Expanded perlite is what we often see a perlite, which is acidic volcanic eruption rock product The production process can be divided into expanded perlite crusher crushing, screening, preheating, rapid heating (1260), cooling and other processes, foremost of which is ...
Perlite is a natural volcanic glass containing combined water. This includes obsidian, perlite, Pitch stone and pumicite. The Perlite was first identified in early 1800 AD. The production was started from 1946 in Superior, Arizona and New Mexico with a trade organisation "The Perlite Institute", in 1949.
Abstract of the Disclosure A process is described for the preparation of perlite ore fines for expansion. The ore fines are treated with an agglomerating agent which has a viscous liquid phase at a temperature above ambient temperature but below the critical dehydration temperature of the perlite ore fines. Suitable agglomerating agents mentioned are the boron acids, particularly orthoboric ...

The expansion process normally takes place at when the perlite ore is rapidly heated to approximately 800-850˚C. For an ideal process, a combined water in raw perlite of 2.77-3.25% would be targeted. The resultant popped or expanded perlite, which is like a glass bubble, has extremely good insulating properties and is light weight.

A thermally efficient process for the expansion of perlite ore is described. The inlet port and burner of a perlite expansion chamber (preferably a vertical expander) are enclosed such that no ambient air can enter the chamber. Air and fuel are metered to the burner with the amount of air being controlled such that the fuel/air premix contains at least enough air to start and maintain minimum ...
Rapidly heating perlite ore to temperatures of about 900°C (1,700°F) softens the volcanic glass causing entrapped water molecules in the rock to turn to steam and expand the particles like popcorn.
Pearlescent sand (expanded perlite for ultra-low temperature super-power engineering) is a product obtained by powder selection of small particles by ore in a vertical shaft kiln using natural gas as a heat source and heating and expanding. The reinforced product is sprayed with silicone on the surface of expanded perlite.
Perlite Preheating Furnace is used to produce high-quality perlite vitrified microbeads, perlite ore for preheating drying. Perlite preheating furnace has been built and put into production all over the world, including the United States, the United Kingdom, Holland, Australia, Russia, India, Thailand and other related industries listed ...

Like its predecessors, the Incon H-22 is a vertical perlite furnace designed within a single, monolithic, self-supporting outer tube with unique systems to preheat both the perlite ore and the combustion air. These systems do not consume additional energy and do not require additional supports and floor space.
Expanded perlite is the perlite ore preheating and instantaneous high temperature baking expansion is made of an internal honeycomb structure of white granular materials.. The principle is: Perlite ore by crushing formed a certain size of ore, the preheating and baking, rapid heating (above 1000 DEG C) and sand moisture vaporizing and in softening containing glassy sand internal expansion, the ...
The principle is: Perlite ore by crushing formed a certain size of ore, the preheating and baking, rapid heating (above 1000 DEG C) and sand moisture vaporizing and in softening containing glassy sand internal expansion, the formation of porous structure. was established in 2008 as a professional Manufacturer&Exporter to provide various mineral
