Finely ground limestone
Very finely ground limestone VMV 1
VMV 1 ground limestone is produced by grinding natural limestone to a very fine grain size.
Area Of Use
Due to its high chemical purity and fineness of grinding, it is particularly suitable for use in the construction industry for the production of building materials, as well as in the glass, chemical and rubber industries.
