Mixed vermiculite

The main types of mixed vermiculite produced in our factory are: 1-3mm, 2-4mm, 10-20 mesh, 20-40 mesh, 40-60 mesh, 80-120 mesh, etc.
The properties and structure of mixed vermiculite
Mixed vermiculite is a layered structure of magnesium containing silicate secondary metamorphic mineral, the original ore is like mica. It is usually formed by the hydrothermal alteration or weathering of the black (gold) mica. Because of its heat loss and dilation, it is flexure like a leech in form, so it is called vermiculite.
The chemical formula of mixed vermiculite is (Mg, Ca) 0.7 (Mg, Fe, Al) 6.0[(Al, Si) 8.0] (OH4.8H2O).
The volume of the mixed vermiculite raw ore can be expanded 8-20 times by high temperature roasting, and the specific gravity after expansion is 130-180kg/m3.
