“…Именно циклический характер сочетания удара с истиранием измельчаемого материала о поверхность, изготовленную из бадделеито-корунда дает хорошие показатели его эксплуатационного применения для пальца в конструкции дезинтегратора [19]. 117 На основании выражения (3) и в соответствии с графиком, показанным на рисунке 4, видно, что применение в дезинтеграторе конструктивно-защищенных пальцев способствует увеличению срока их службы (по сравнению со стальными пальцами, изготовленными из закаленной стали) в 1,4 раза.…”

A method for assessing the wear resistance of round impact elements of a disintegrator is considered using the example of grinding highly abrasive mica-crystalline materials (expanded vermiculite and its concentrate) in a disintegrator. A constructive method for protecting the working surfaces of impact elements from abrasive wear when dispersing similar materials in a disintegrator of a developed design is presented. Using mathematical expressions to estimate the wear parameters of the impact elements of the mill, experimental values of the wear of the impact elements were obtained depending on the linear speed of the impact element, the reduced productivity of the disintegrator, the weighted average size of the crushed particles, the strength of the crushed raw materials and the hardness of the material from which the impact elements are made. The differentiated influence of variable factors on the process of abrasive wear of the surfaces of the impact elements of the disintegrator has been determined. Using a graphical interpretation of the results of experimental studies of the process of abrasive wear of the impact elements of the disintegrator, it was established that the wear of the impact elements mainly depends on the productivity of the unit (mill throughput). As the productivity of the disintegrator increases, the specific wear of the working elements decreases due to a decrease in the flow density of the moving material inside the mill, regardless of its high absolute speed inside the grinding chamber. In order to reduce the surface abrasive wear of the impact elements of the disintegrator, the effectiveness of using special protective bushings made of baddeleyite-corundum materials, resistant to abrasive wear by silicate mica-crystalline rocks, was proposed and experimentally confirmed. A comparison was made of the proposed design solution for protecting the working surfaces of impact elements with previously used impact elements made of grade 45 steel hardened to HRC 50.

The article is aimed at increasing the durability of the working bodies of rotary-vortex mills, which are widely used in the production of dry building mixes. The description of the device of a rotary-vortex mill is given. The article proposes a new method developed by scientists of the V.G. Shukhov BSTU to increase the durability of the mill's working bodies by applying cells with dimensions on their surfaces that allow particles of the crushed material to be pressed into them, and thereby protect the surface from rapid wear. As a result of an analytical study of the force interaction of the crushed material with the surface of the beale cell, an equation was obtained to determine the geometric dimensions of the cell, allowing due to friction forces to keep the volume of particles of the pressed material from falling out of it. It is established that the dimensions of the cell are interconnected and are determined in such a way that the resulting pushing force is equal to or less than the holding force (friction force). It is proved that the pressing of particles of the crushed material, in rectangular cells of the deposited mesh on the working surface of the bat, is largely determined by the geometric dimensions of the cell, and also depends on the physical and mechanical characteristics of the crushed materials. The design of the bill is proposed, which allows to increase its durability by reducing the contact area of the crushed material with the working surface of the bill.
