FIELD: mining engineering.
SUBSTANCE: in the process of ore crushing using a plate running in a stable mode, operate the crushing device in the form of plates mounted in front of a hopper consisting of the constituent elements, for example steel blocks (cubes, or short rods) embedded into the steel base of the cells, and the mass metal construction commensurate magnitude of impact loads (drop height and ore size pieces), and operating in the dynamic mode. To stabilise the operation of the crushing device, it is placed in a vessel like a box of blocks, on the bottom of which a material of the sand type is poured, which ensures the deformation of the crushing device in the form of a plate, in a vertical plane (vertically), and the metal box is mounted on a reinforced concrete or rock foundation made with a slope of 5-6° toward the array to exclude bias towards the hopper, and link them with strings and anchors with a side array for stability. The box does not have the freedom of displacement in the horizontal plane also because of the pancake-shaped design. In the process of work, the dismountable design allows replacing the decommissioned ones due to the use of steel cubes or rods, collecting the crushed material is produced in a hopper whose slope from the vertical varies depending on the energy loads and the height of the falling pieces and is 45-50° for deep rudispours.
EFFECT: increasing the efficiency of bypass works, increasing the degree of crushing ore.
