Change of physico-chemical properties by mechanical activation of zeolites

Abstract

The study (Navbakhor district of Navoi region) consists of the study of the properties of natural (mining) bentonite mineral raw material to its physical and chemical properties through mechanical activation. X-ray phase and X-ray spectral analysis of the composition of the layer montmorillonite was performed. Mechanical and chemical activation of zeolites to change the surface area and particle size was carried out using a high-power mill AGO-3 and a conical vibrating grinder VKMD-6. The dependence of the mechanical activation of layer montmorillonite on time over 20s, 40s, 80s and 160s proved that it increases the surface area. Using the Karman-Kozeni method, optimal regimes were determined by doubling the mechanical activation time and studying the density, sorption properties, and specific surface area of the zeolite.
