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, dealed with the rapid heating (1000℃ above). ...

It is then placed inside furnace where at a temperature of 1400-1800 degrees, the water trapped inside escapes after becoming steam. Packaging of Perlite ore foundries is done in 50kg bags. The chemical composition of Perlite ore supplied by KARNATAKA SILICATES is as follows. SiO2 (Silicon Dioxide-70-75%)

The perlite expansion furnace is also called Perlite Expander Kiln, it is specially used to expanding perlite ore. Perlite expansion furnace work process: What is perlite ore ? Perlite ore is an amorphous volcanic glass, typically formed by the perlite, obsidian, pitchstone. It can be greatly expanding when heated sufficiently.

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 ...

The desirable perlite feeding rate is achieved by a rotary air-lock feeder, through a 0.08 m diameter central hole. The rotary air-lock feeder prevents hot air upward drafts but also the escape of ...

The Benefits of Perlite as Insulation. When perlite ore is expanded by exposure to rapid, controlled heating, it grows up to 20 times its original volume and takes on a -like cellular internal structure — essentially …

Perfect to resist heat conduction! With further help from the Arizona Department of Mineral Resources, he discovered why—perlite contains a small percentage of trapped water in the raw ore. They also worked to …

Perlite is a naturally occurring siliceous volcanic rock containing two to six per cent combined water. When the crude rock is crushed and heated above 1600° F ( 871° C), the combined water vaporizes and the perlite expands four to twenty times its original volume. This expansion process creates countless cells in the glassy particles, which ...
