2021-09-24

Bentonite is a non-metallic mineral with montmorillonite as its main mineral component and its content is 85-90%. The mosh hardness of bentonite is 1-2. The density is 2-3g/cm³. It has different colors, like white, light yellow, light grey, light green, pink, brown red, brick red, grey black and so on because of the change of iron content.CJmUltrafine Grinder, Ultrafine Mill For Sale
