It is shown that the volume of crushed stone consumption as a main component for road construction and production of building structures made of concrete are constantly growing both in Russia and the whole world. At that, requirements for the quality of products, cost efficiency and sustainability of the production are increased. One of the new requirements for crushed stone is a minimal content of platelet-shaped and needle-shaped grains. A comparative analysis of technical characteristics of various crushing units and techniques on their basis for producing the cubiform crushed stone is presented. It is shown that the most efficient units for producing the cubiform crushed stone are cone inertial crushers developed at Research and Engineering Corporation “Mekhanobrtekhnika”. The scientific basis of vibration crushing technique is revealed. Examples of the successful operation of the cone inertial crushers and vibrating screens at the enterprises of Kazakhstan, where two-stage and one-stage crushing schemes were realized, are presented.
