About Production of High-Quality Cubiform Crushed Stone
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 growingboth 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 forcrushed 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 theirbasis 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 atResearch and Engineering Corporation “Mekhanobrtekhnika”. The scientific basis of vibration crushing technique is revealed. Examples of the successful operation of the cone inertialcrushers and vibrating screens at the enterprises of Kazakhstan, where two-stage and one-stage crushing schemes were realized, are presented.
