The influence of the frequency variation of the cone crusher motorized cone

All three curves show that in the case of exciter static torque constant , increasing the frequency of the moving cone crusher processing capacity gradually decreased . But this decline is nonlinear, because according to Equation 12-5 , ω increases, so that the crushing force F is increased by the square relationship , thus weakening the ω decline in the processing capacity .It can be seen from FIG YIFAN-056 , the frequency is increased, resulting in the material crushing ratio increases, a weighted average diameter of the product reduces .

Figure 12-2c shows that , within a small range , to increase the frequency , can improve the crushed product in the 28 % -45% of the less than 1.25mm fractionated products .

FIG YIFAN-056  

Figure YIFAN-056 represents the processing power and frequency relationship of the moving cone .

Crushing force of the material unit of 2MPa the case , the frequency increases greater impact on the three parameters , because , under these conditions , the centrifugal force of the moving cone growth high ( unit breaking force of 4MPa), so that a relatively higher density .

Therefore, the results show that the change in frequency of the moving cone is a very effective way to control the crushing ratio hours centrifugal force values ??of the exciter , this method is more reasonable . In this case , it is guaranteed to improve the reliability of the sliding bearing and away from resonance , i.e. the natural frequency, the amplitude of the lower housing away from the rubber buffer .
