Yushunxin fertilizer production equipment
The vibration screen machine adopts tube type eccentric shaft vibration exciter and partial block to adjust the swing. The material screening flow line is long, various screening size. It has the advantages of reliable structure, strong exciting force, high screening efficiency, small vibration noise, durable, easy maintenance and safety in use. The vibration screen machine is widely used in organic fertilizer, compound fertilizer, mining, building materials, transportation, energy and chemical industry.
It consists of a screening box, a vibrator, a suspension (or support) device and an electric motor.
Working Principle
The vibrating screening mesh is operated by the reciprocating rotary vibration which is generated by the vibrator excitation. The upper rotating heavy hammer of the vibrator causes the screen plane to whirling vibration, while the lower rotating heavy hammer causes the sieve surface to produce a conical rotary vibration, and the combined effect of the rotating heavy hammer causes the screen surface to produce the complex rotary vibration. The vibration trajectory is a complex space curve. The curve is projected into a circle on the horizontal plane, and the projection on the vertical plane is an ellipse. By adjusting the exciting force of the upper and lower heavy hammer, the amplitude can be changed. While adjusting the space phase angle of the upper and lower heavy hammer, the curve shape of the screen surface movement track can be changed, and the movement track of the material on the screen surface can be changed.
