The feature of expanded perlite as the best natural sorbent, to absorb, for a long time keep and slowly issue ions of feeding elements to the environment, can be used for putting it with mineral and organic manure to soil.
More DetailsThe 37BPRL is a super coarse perlite. Perlite is a volcanic mineral that is capable of greatly expanding from four to twenty times from its original size when heated at around 1600° F. Upon expanding, the perlite becomes lighter in weight and capable of absorbing exterior moisture from a particle. Due to its low density following processing, this product is suitable for horticultural purposes ...
More DetailsIn the furnace, the perlite ore reaches a temperature of 760 to 980 E C (1400 to 1800 E F), at which point it begins to soften to a plastic state where the entrapped combined water is released as steam.
More DetailsPerlite is a naturally occurring amorphous volcanic glass formed by the rapid cooling and solidification of volcanic lava, which traps crystalline water into its mass. The process of exfoliating perlite is based on the presence of 2-6% combined water in raw perlite rock.
More DetailsThe physical character of expanded perlite lends itself to a variety of special purposes –including use in insulating cryogenic and low temperature storage tanks, in shipping containers, cold boxes, test chambers, and in food processing.
More DetailsPerlite is one of nature''s most versatile and efficient minerals. It is formed by molten (magma-tic) rock, also known as volcanic glass. Over time, and during formation and cooling, water is absorbed into the raw perlite ore matrix, giving perlite its unique ability to expand when heated.

More DetailsPearlite is a two-phased, lamellar (or layered) structure composed of alternating layers of ferrite (87.5 wt%) and cementite (12.5 wt%) that occurs in some steels and cast irons. During slow cooling of an iron-carbon alloy, pearlite forms by a eutectoid reaction as austenite cools below 723 °C (1,333 °F) (the eutectoid temperature). Pearlite ...
More Details· 3.2. Perlite melt thermophysical properties Perlite ore particles obtained from the Trachilas and Tsigrado mines (Milos island, Greece) are considered in this modeling study, consisting of amorphous silica (73% wt. SiO 2), aluminium oxide (12.7% Al 2 O 3), other metal oxide amounts (K 2 O, Na 2 O, Fe 2 O 3, CaO) and 3.32% LOI (Lost On Ignition) matter.
More DetailsReusing perlite without processing to grow successive crops is potentially risky because of media compaction, salt buildup, and pest contamination (Hanna and Smith, 2002). Replacing used perlite with new media to raise successive crops is costly, and recovering the expense by selling the product at a higher price may not work well in a competitive market.

More DetailsIn its natural state perlite is brown or black in color, as it''s typically formed during the cooling process of lava that produces obsidian. During processing, raw perlite is superheated very rapidly to temperatures of 1560°F to 1650°F, which causes the material to soften and the moisture inside the glass to …
More DetailsPerlite, as required for the light weight aggregate industry, must be closely graded and the amount of minus 100 and minus 200 mesh perlite must be closely controlled. Perlite, being very brittle and friable, demands precautions throughout the flowsheet to eliminate excessive fines. Perlite Process Flowsheet The flowsheet illustrated is applicable for various tonnages from 50 to 400 tons per 8 ...

More DetailsOver time, and during formation and cooling, water is absorbed into the raw perlite ore matrix, giving perlite its unique ability to expand when heated. When perlite ore is heated rapidly in industrial furnaces, the volcanic glass softens, causing the entrapped water molecules to turn to steam and expand the perlite particles—much like popcorn.

More DetailsPerlite is most needed in the soil mix of plants grown in containers. Plants that naturally grow in dry areas will benefit most from the addition of perlite to their potting mix. Perlite is safe for organic gardens, as it is chemically inert. It will help to hold air in the soil, keeping the plants from suffocating.
