To overcome these established drawbacks, a new perlite expansion process has been designed on the basis of a vertical electrically heated expansion furnace. The novel furnace enables precise control of experimental conditions, in order to allow for efficient adjustment of particle residence time and internal temperature.
Because of their vertical integration, all aspects of production are controlled, from mining to expansion, enabling a greater degree of quality control while offering a more consistent perlite product and cost savings to the customer. Supplier. Choosing a perlite supplier is a major decision for any grower, commercial or small scale.
Grace expands one size of perlite ore, for horticultural uses, in its Perlite Corporation Model VS-450 vertical expansion furnace. During emission testing, Grefco NA 79 ore was processed. The pre-sized perlite concentrate is fed into the 0.7-m (28-in.) -diameter stainless steel furnace through a surge preheater at a rate of about 0.91 mg/h (1 ...

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.
A short video describing the mining and processing of Perlite ore for horticultural, construction, and industrial applications.
Perlite Expansion Furnace are specially used to manufacture closed pearlites, hollow pearlite vitrification microsphere. Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently.
perlite expansion technology Raw perlite ore is delivered with big bags and directly blown through a fill pipe into the crude perlite storage tank. Via the dosing weigher crude ore enteres a distributor and from there is fed via two inlets into the blowing furnace.
The expansion of the vertical raft is 25-35m3 per hour, and the daily output of expanded perlite is 300 cubic meters, which fully meets the sales needs. Compared with the old-fashioned expansion equipment, the output is increased by nearly 20%.
Perlite filter aid is a powdered chemical product with a certain particle size obtained by selective expansion of selected small-sized ore sands, heated by purified gas, in a vertical shaft kiln, expansion, and grinding and purification.
Expanded perlite constitutes one of the most competitive insulating materials that is widely used in construction and manufacturing industry due to its unique properties combination; it is white, natural, lightweight, chemically inert, and exhibits superior insulating properties (thermal and acoustic) and fire resistance. Conventionally, perlite expansion is performed in vertical gas …
