Usage advanced technological methods for the recovery of cone crusher equipment

Abstract

Cone crushers of various sizes and modifications are used widely for rock processing now. The most widespread are crushers of the KDM and KMDT types. Depending on the types and modifications, crushers are used in various industries: crushing abrasive, extra strong rocks and building materials, in the production of cement and other materials in the construction industry; for crushing rocks in the mining industry.

Substantiation of the main parameters of a hammer crusher for grinding municipal solid waste

“…The crushing of MSW components is in demand for a number of reasons: firstly, the efficiency of subsequent operations increases; secondly, due to the crushing of waste, the number of vehicles involved will be reduced by approximately 25-30 percent; thirdly, the negative impact of waste on the environment will be significantly reduced; fourthly, shredded waste can serve as a secondary raw material for agriculture. In addition, it is important to note that by reducing the volume of waste disposal, the life of landfills increases, as well as saving land resources used when filling waste, which in turn affects the cost of their disposal [2,3].…”

The analytical dependence of the resistance force to digging with a bulldozer blade on the main influencing factors

“…Physical modeling can be used to find a solution to a problem when the phenomenon under study is so complicated that it is not possible to compile a satisfactory mathematical model for it, or the solution to the formulated problem fails to compile a satisfactory mathematical model for it, or the solution to the formulated problem encounters insurmountable mathematical difficulties. On the other hand, this method can significantly reduce the cost of experiments, including those aimed at testing analytical solutions [5][6][7].…”

Modeling of segmental excavator working tool for soil compaction

“…The choice of rational design parameters and modes of operation of the SWT and the evaluation of its effectiveness were conducted using PM methods, which can significantly reduce the complexity and cost of research [13][14][15][16][17][18]. The use of largescale PMs for the compaction of the most representative soils (in particular, loamy soils) allows the simplest way to establish the productivity of the process of soil compaction to a state of standard density and rational energy costs corresponding to this productivity.…”

“…On the contrary, the scheme of interaction of a rigid wheel with a deformable base is characterized by an excess of the length of the contact zone of the wheel with soil in the radial plane compared to the axial size of this zone. The fundamental significance of these distinctive features is explained by the fact that the minimum length of the contact zone of a cylindrical or another surface with the compacted soil determines the depth of formation of a compacted core and, thus, the depth of soil compaction to a given density value [18]. Therefore, for a rigid wheel, the width of which, as a rule, is less than the radius, the effect of soil compaction and its viscous-plastic flow, i.e., the passing ability of the wheel mover, is determined mainly by the width of the wheel, and for a smooth wheel roller or a cylindrical compacting segment, this effect is mainly determined by the radius of curvature of the cylindrical generatrix of the surface.…”
