Ningshu has a process line for expanded vermiculite. Vermiculite, a mineral, hydrated magnesium aluminium silicate with a highly variable and complicated chemical compound. It crystallises in a monoclinic crystal system, in most of cases in a form of plate clutches. Yellowish, brown, olive colour. It is a product of mica (phlogopite or biotite) erosion. It is mainly mined in the USA, Africa (South Africa and Madagascar), Australia, Asia (China). In Poland, it is found at Lower Silesia, but in volumes not suitable for mining.
A specific property of vermiculite is volume increase (even 30 times) during high temperature treatment, and in this process, expanded vermiculite is produced. Vermiculite in exfoliated (expanded/expanded) form is light, inflammable, compressive, highly absorbable, inert and may have high positive ions exchange ability.
Expanded vermiculite is a good sound and heat insulator (inflammable) suitable for temperatures from below -200° C to +1200° C.

- In the industry - wherever insulation of high- or low-temperature manufacturing processes is required, as a filler, etc.
- In gardening (as an additive to multi-compound substrates, improving water and air relations, a carrier of positive ions)
- In animal husbandry, as an additive to forage (a carrier of vitamins and minerals) as well as a padding for animals.
