Vibratory screen machine use the vibration motor as a power source. Vibration motor vibration body on different installation combinations, can produce different vibration running track, so as to effectively complete a variety of jobs.
Linear Vibration: vibrating screen uses dual vibration motors, when the two vibration motors to synchronize and reverse rotation, the eccentric force generated by the exciting cancel each other in a direction parallel to the axis of the motor, the motor shaft perpendicular to the the direction of the stack is a force, and therefore the trajectory of the screening machine is a straight line. Its two-motor axis relative to the screen surface with a dip in the excitation force and material from under the joint effect of gravity, the material being thrown at the screen surface leap forward in a straight line, so as to achieve the purpose of screening and classification of materials.
Circular or elliptical vibration: the trajectory of the vibrating body in a vibration level of the projection surface is a straight line, and in the vertical plane of projection of a circle or an ellipse, its form is called circular or elliptical vibration of vibration. Such shaker to be known round or circular vibrating sieve shaker. Usually a vibration motor is mounted on the vibration machine body, can produce this movement. Round or oval vibration and the vibration in the plane perpendicular to the motor shaft, then look at the form of the relative position of the vibration motor and the whole center of gravity.
Composite Vibration: vibration body is produced by two excitation system, the vibration form is called a composite vibration. Generally have dual-band and dual-width composite complex forms. Some special properties of vibration screening equipment, using two different models of different speed vibrating motor, packed in by the feed end and the discharge end of the screening equipment, so that by the feed-side rendering large amplitude low-frequency vibration, while the feed-side rendering vibration screening equipment small amplitude high-frequency vibration in the middle of two overlapping, so screening equipment to play the role of a more effective screening.
Rotary vibration,is also known as three-dimensional vibration: vibration trajectory vibrating body in the horizontal plane of projection is a circle or ellipse, the vibration form is called spin vibration. Such shaker to be known vibration sieve. Vibration can be divided into flat spin spin vibration, vibration and complex spin vortex-type three forms of vibration. When the vibration locus of the projection of the vibrating body to a vertical plane by a horizontal line, the vibration form is called flat rotating vibration; when the trajectory of the vibrating body in the vertical plane of projection of a straight line are inclined, the vibration form is called the scroll-type vibration; track when the vibrating body vibration in the vertical plane for the projection of a circle or ellipse, its vibration form called complex spin vibration. Usually consists of vertical vibration motor vibration equipment generates spin excitation vibration, the vibration in the form of both ends of the look angle vertical vibration motor excitation block may be. Also be two foot-mounted vibration motor vibration sides packing equipment, it was a set of shaft angle, the vibration will also produce spin vibration.
