2. Obtaining vermiculite small particles . Natural vermiculite flakes are characterized by high values of aspect ratio. In clay science, exfoliation involves a degree of separation of the layers of a host structure where units, either individual layers or stacking of several layers, are dispersed (freely oriented and independent) in a solvent or …
Vermiculite: What Is It and How to Process It? | Fote Machinery
The calcined expanded vermiculite should immediately enter the cooling machine or be cooled naturally. The FTM Machinery cooling machine can cool the clinker coming out of the rotary kiln to below 200°C, maintaining the strength of the vermiculite without embrittlement, while improving the quality and grindability of the clinker.
Understanding The Composition And Uses Of Vermiculite
During the mining process, large machinery and equipment are used to dig and remove the vermiculite ore from the ground. This ore is typically found in deposits that contain other minerals such as mica and feldspar. ... causing it to expand and exfoliate into accordion-like layers. This process is known as exfoliation, and it is what gives ...

On the mechanism of exfoliation of 'Vermiculite'
This mechanism provides a common explanation for the exfoliation of 'Vermiculite' by thermal methods or by treatment with H 2 O 2. Paradoxically, one sample which consists of pure vermiculite, in the mineralogical sense of the term, demonstrates that pure vermiculite does not and should not exhibit the property of exfoliation.
