Crude perlite expanded for use as a concrete aggregate ranges from 1 mm (plus 16 mesh) to mm (plus 100 mesh). Ninety percent of the crude perlite ore expanded for horticultural uses is greater than 841 µm (20 mesh). Crude perlite is mined using openpit methods and then is moved to the plant site where it is stockpiled. Read More
This distinguishing feature which sets Perlite apart from other volcanic siliceous rocks is that when heated above 1000°C, it expands up to twenty times its original size. The expansion is due to the presence of a few % combined water in the crude ore. When processed at proper temperatures, the crude ore pops in a manner similar to popcorn.
Crude oil sludges and other relatively heavy hydrocarbon liquid sludges are mixed with diatomaceous earth or perlite to form a friable and flowable solids mixture which is conveyed to a combustion unit, such as rotary kiln, calciner or lift pipe type combustor, wherein combustion of the hydrocarbons is carried out to provide gaseous combustion products and a substantially .

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 ...
