Analysis for the force exerting to crushing welt is carried out based on the situation of force exerting to welt during the material crushing process.
In
addition, the situation of exerting material of different cavity
crushing to material is analyzed based on the operating status of
material crushing process.
The optimal design of structure of crushing plate is carried out based on the crushing requirement, material characteristics and wear characteristics of welt.
And then the optimal design of cone crusher cavity——the classic cavity of plate is carried out.
The cavity of plate roller crusher is established.
The design of cavity adopts plane design.
And the target of design is the equal head and underneath of cavity, the unobstructed discharge of the cavity and the approximation of unobstructed cavity.
The virtual model of plate roller crusher is established by 3D Software, Pro/E, based on the design requirement of crushing machinery.
The crushing force of material in different motion parameter is
simulated and analyzed.
The crushing force curve of roller vibration in different frequency is analyzed.
Under impulse load, the frequency of motion of roller is changed, without changing the vibration amplitude.
The comparative analysis of crushing force exerting to material in 0Hz, 20Hz, 50Hz and 80Hz is made.
And the relation of crushing force to frequency is analyzed.
The analysis is helpful to the further study of material vibratory crushing mechanism and cavity.
It is also helpful to the through study in crushing theory and the design improvement of plate roller crusher.
It is helpful to the improvement of crushing performance and crushing production capacity, too.
Finally, in terms of crushing dolomite, hammer crusher and impact crusher are the crushing equipments without any doubt.
The crushing efficiency could be very high when we use hammer crusher, even higher than customers’ expectation.
Besides, the product granularity is quite small, which totally meets the standard requirements of production.
