The movement equation of nonlinear space double-mass vibrator dryer based on the old linear vibrator dryer was established, a series parameters such as the average vibration resistance of the axises of the two motors, the index number of synchronism and stability and so on were gained. The synchronism of vibration of the space-moved mechanical system could be realized on the condition of vibration amortization which should need for the two-motor's rotating dislocation less than 1.3%, no-symmetric setting dislocation less than 0.3%. Applying it to the project scene, lead to a new equipment——ZHF-3 double-mass nonlinear vibrator dryer. Practical operation effect showed that dryer has the characteristics of low cost, low obstacles, high stabilization, high efficiency and good prospect.
