Main feature of the present utility model is exciting force, amplitude, the parameter variation ranges such as frequency, oscillation intensity that shake are big, can control effectively to its size, action time by frequency converter.
During vibrating mill work running, the medium-high frequency impact that mill is situated between and strong abrasive action are levigate with material, and this process causes particle to crack mainly due to grinding the repeated stock that is situated between with abrasive material in the cylindrical shell. When solid deformed, new surface just grew up as the basis gradually take these crackles, after the unloading, under the effect of molecular force, they are " healing " again, and when just underwent mutation in the place of defective maximum in the weakest indivedual places, solid will produce the destruction of macroscopic view. And mill is situated between to the percussion of abrasive material in the vibromill, making these microfissues have little time " healing " is just continuously impacted, the fast expanding microscopic checks, the continuous expansion of crackle is effective so that pulverize so vibrate, collide, impact the fine grinding of carrying out solid material with this.
Because physical dimension of the present utility model is big, output is high, work is continuous, and there is the impact of random maxima load, so the noise that produces is bigger, if do not take suitable vibration isolation measure, will very big dynamic loading pass to the basis, make ground and building produce harmful vibration, not only produce the noise pollution environment, in the serious situation, can make machine breakdown and stop production, and long-continued operation, not only this machine life-span shortens greatly, also can exert an influence to peripheral equipment and building.
Mirror be designed to the double-mass vibrating grinding machine in this present invention, the main mode of shaking is not only arranged, and vibration isolation mode is arranged. The main mode of shaking adopts the medium or low and medium frequency of suitable size, to satisfy system's need of work under the Near resonance oscillating state, make machinery produce the required driving force of vibration, reduce away from the vibrating mill of working under the resonance state, to realize energy saving of system, reach the purpose of the big driving of small-power.
The vibration isolation model frequency is little far beyond the main mode of shaking, shock-absorbing spring 25 can adopt the elastomeric material spring, has nonlinear characteristic, can reduce the Dynamic Coupling on exciting source and basis and exciting force, oscillation intensity to the transmission on basis, play effectively absorbing effect, reduce the dynamic loading of passing to the basis, the noise that system is produced reduces greatly; Adopt on the one hand the blimp 16 with good soundproof effect that whole working machine is covered, reach further effectively noise reduction, play simultaneously the raising mill efficiency, improve the purpose of working environment.
