Golden Expanded Vermiculite for Agriculture and Horticulture Rotary kiln
Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and commercial furnaces can routinely produce this effect. Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite.
Vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance. It is found in various parts of the world, vermiculite is basically a hydrated phlogopite mica which has the remarkable ability to expand to many times its original volume when heated at 850 -1100°C.

Crude vermiculite consists of golden and silver vermiculite which are carefully classified into many sizes ,includes0.3-1mm1.5-2.5mm0.5-1.41mm1-2mm2-4mm3-6mm4-8mm.
The exfoliation process is carried out commercially by passing crude vermiculite through a furnace chamber in a controlled manner. The crude vermiculite then expands at right angles to the cleavage planes, producing concertina-shaped particles many times their original volume.Exfoliated vermiculite size ,includes 0.3-1mm1-3mm1-2mm2-4mm2-3mm 3-5mm3-6mm4-8mm6-8mm,special size can be done as per customer's demands.
