The main function of vibrating screen
Light fine vibrating screen can be divided into rotating vibrating screen, straight line sieve, straight row sieve, ultrasonic vibrating screen, filter screen, etc., can be referred to vibrating screen series.Experimental vibrating screen: impact screen, top impact sieve shaker, standard test screen, electric vibrating screen machine, please refer to the experimental equipment.According to the running track of the vibrating screen, the material can be divided into two parts:According to the linear motion track: linear vibrating screen (material on the screen surface to move forward in a straight line)According to the circular trajectory: circular vibrating screen (material on the screen surface for circular motion) structure and advantagesAccording to the reciprocating motion trajectory: fine screen (material in the sun surface reciprocating movement)Vibrating screen is mainly divided into linear vibrating screen, round vibrating screen and high frequency vibrating screen. Vibrating screen according to the type of vibrator, vibration can be screened as a single axis vibration sieve and biaxial vibrating screen. The single axle vibration screen is used to make the sieve box vibrate by the single unbalanced and exciting vibration, the screen surface is inclined, and the moving track of the sieve case is generally round or oval. The double axle vibrating screen is a double unbalanced heavy exciting vibration with synchronous different direction rotating, the screen surface is horizontal or slowly inclined, and the movement path of the sieve case is straight. Vibrating screen has inertial vibrating screen, eccentric vibrating screen, self centering vibrating screen and electromagnetic vibrating screen and so on.
Vibration screening equipment according to weight, use can be divided into: Mining vibrating screen, light fine vibrating screen, experimental sieve machineMine vibrating screen can be divided into high efficiency heavy duty sieve, self centering vibrating screen, elliptical ellipse vibrating screen, dewatering sieve, round vibrating screen, vibrating screen (4 pieces), banana sieve, linear vibrating screen, etc..
The vibrating screen is operated by the complex rotary vibration generated by the vibration of the vibrator. The upper rotating heavy hammer of the vibrator causes the screen surface to produce a plane whirling vibration, while the lower rotating heavy hammer causes the screen surface to have a conical rotary vibration, and the combined action of the rotating heavy hammer causes the screen surface to generate a complex rotary vibration. The vibration trajectory is a complex space curve. The curve is projected on the horizontal surface into a circle, and the projection on the vertical surface is an ellipse. Adjusting the exciting force of the upper and lower rotating weights can change the amplitude. While adjusting the spatial phase angle of the upper and lower heavy weights, 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.
