Introduction of Expanded Vermiculite

Vermiculite is a hydrate, which is massive and flaky. The volume of interlayer water molecule increased 6-15 times after being burned at high temperature. Rich in nitrogen, phosphorus, potassium, aluminum, iron, magnesium, silicate and other components. Vermiculite has higher layer charge number, so it has higher cation exchange capacity and stronger cation exchange adsorption capacity. Characteristic: light weight, good water and fertilizer adsorption performance, non-decay, can be used for 3-5 years.

The raw vermiculite ore is roasted at high temperature and becomes expanded vermiculite. The conventional size specifications of expanded vermiculite are 0.5-1 mm, 1-3 mm, 2-4 mm, 3-6 mm, 1-6 mm, etc. In addition, other granularity models can also be produced according to customers'production needs. Vermiculite powder is made from raw vermiculite ore by high temperature roasting, screening and grinding. The main models are 20-40 mesh, 40-60 mesh, 60-80 mesh, 200 mesh and 325 mesh.
