    Analysis on the Energy Consumption of the Jaw Crusher

    AUTHOR: admin       DATE: 26 Jul 2012 08:16:20

    Nowadays,along with the mineral resources exploitation, ferrous metallurgy, nonferrous metallurgy, light industry, chemical industry and mineral resources become increasingly depleted, extraction also will be a substantial increase in the amount of materials used in the building materials, bridge, road, dam but also the rapid increase. The first process makes the material processing - crushing operations is particularly important. According to incomplete statistics, the power consumption of the crushing operations accounted for more than half of the total electricity consumption of the concentrator. The national annual electricity consumption in crushing operations is in the 2 × 10 ^ 9kw.above. Therefore, the design and manufacture of energy saving, efficient jaw crusher which can reduce the energy consumption of the jaw crusher material, is of great practical significance.

    Red star heavy industry’ tips:

    First of all, the macroscopic mechanical response is that with the increasing load, a variety of micro-cracks, micro-pore has continuous development, and thus forms a macroscopic crack, and eventually the fracture leads to material broken. Different in the crushing process, the evolution of a large number of micro-defects in materials with a certain degree of randomness and statistical differences in the evolution eventually will lead to the macroscopic mechanical response of materials, such as uneven local deformation, failure mode and undermine the morphological differences, and so on. The material deformation destruction of the complexity of the phenomenon illustrates that the evolution of the material of the internal variety of micro-defects on the macroscopic mechanical response of materials has great influence. The evolution of this micro-defect will inevitably consume some of the energy to form a new surface, resulting in the material deformation and failure process of energy dissipation.

    Materials in the crushing process will produce the acoustic emission, it is essentially a flexible part of the conversion to elastic vibration energy, resulting in the propagation of sound waves in the material stored within the material. This transformation is closely related to the defect evolution in the material, especially accompanied by the generation of new defects will inevitably bring about the release of elastic energy, leading to the emergence of sound waves. Due to damping within the material, what the sound wave is propagation in the material will inevitably occur decay, resulting in some of the energy dissipated by heat or other forms. Thus, although the nature of acoustic emission is an energy conversion, because of the characteristics of the material internal organizational structure, this transformation will also cause the dissipation of energy, which is part of the elastic vibration resistance of the materials consumption dissipated.
