To ensure the uniformity of perlite rock in terms of density, a device of the simplest design has been developed, based on the Archimedes law, which allows determining the mass and volume of perlite rock right at the field and determining the average rock density from the obtained nomogram. The main physical and mechanical properties, closely correlated with the average density of the rock, are determined by calculation using the formulas obtained. The research carried out makes it possible to introduce the concept of grade and to stack the mined rock by density right on the quarry.
