In the sand production line, the crusher can be fed continuously and evenly to avoid the blockage of the crusher's receiving port. The machine uses the rotation of the eccentric mass in the vibrator to generate centrifugal force, so that the movable parts such as the screen box and the vibrator make forced continuous circular or approximate circular motion. The materials follow the screen box for continuous throwing motion on the inclined screen surface, and continuously and uniformly send the materials to the receiving port.

Generally, it is composed of a vibrating frame, a vibrating body, a vibrating motor, a vibration exciter, a spring (the spring is divided into an excitation spring and a support spring), etc. The picture on the right shows the general ZG activated vibration coal feed system used in power plants structure. ZG type activated vibrating coal feeder is a double-mass linear sub-resonant vibration machine. Its system is mainly composed of five parts: resonance body, activation cone, vibration exciter, vibration motor and elastic elements.

1) Resonant body—The resonant body is connected to the exciter through an excitation spring, and the excitation force generated by the exciter is driven to make the approximate simple harmonic motion of the natural frequency. Its quality is an important parameter in the vibration system, and the resonant body must have sufficient rigidity and strength.
2) Activation cone——The activation cone is a wedge-shaped discharge plate with the small head upwards and fixed on the resonance body. Due to the excitation force generated by the exciter, the activation cone and the resonance body are similar in the direction of vibration. Simple harmonic vibration. The upward force is generated by the activation cone to transmit the horizontal vibration to the top material, and the disturbance energy generated by the vibration force loosens the material to make it fall.
3) Elastic elements-elastic elements mainly include excitation springs and support springs (also called vibration isolation springs). The excitation spring is the main accessory that transmits the excitation force. The support spring mainly supports the vibrating machine body, so that the machine body realizes the required vibration and reduces the dynamic load transmitted to the foundation or frame.
4) Vibration exciter-the vibration source of the vibrating coal feeder, which is used to generate periodically changing excitation force to make the resonant body produce continuous vibration. Vibration exciter is a key component of this vibration equipment. The magnitude of the exciting force it generates directly affects the amplitude of the resonant body, and its alternating frequency is the working frequency of the vibrating coal feeder. Commonly used exciters are inertial exciters, elastic link exciters, electromagnetic exciters, hydraulic or pneumatic exciters, and cam exciters. The vibration exciter of this equipment is a cam type vibration exciter. The cam type vibration exciter is composed of a pair of variable force wheels. The excitation force generated by the vibration exciter determines the amplitude of the resonance body, and the discharge of the coal feeder The amount is mainly determined by the amplitude of the resonance body. After the variable force wheel is used, the activated vibrating coal feeder can realize stepless speed regulation.
5) Vibration motor-This equipment is operated by two vibration motors respectively driving the exciting force generated by the exciter. The two vibration motors and a pair of variable force wheels form a two-mass body, which is supported by a spring and a base. Connected and do not vibrate with the vibration of the resonant body.

(2) Avoid frequently starting high-power equipment.

 The vibrating feeder uses the rotation of the eccentric mass in the vibrator to generate centrifugal force, so that the movable parts such as the screen box and the vibrator make forced continuous circular or approximate circular motion. The vibrating feeder is composed of a feeding trough, a vibration exciter, a spring support, and a transmission device. The vibration source of the trough vibrating feed is a vibration exciter, which is composed of two eccentric shafts (active and passive) and a gear pair. The motor drives the active shaft through the V-belt, and the gear on the active shaft meshes with the passive shaft. When rotating, the active and passive shafts rotate in opposite directions at the same time, which makes the tank vibrate, so that the materials flow continuously, and the purpose of conveying materials is achieved.

The vibrating feeder has simple structure, uniform feeding, good continuous performance, adjustable excitation force; changing and controlling the flow at any time, easy to operate; eccentric block is the excitation source, low noise, low power consumption, good adjustment performance, no impact Material phenomenon; if a closed body is used, it can prevent dust pollution, stable vibration, reliable work, and long life; the excitation force can be adjusted, the flow can be changed and controlled at any time, and the adjustment is convenient and stable; the vibration motor is the excitation source, with low noise and consumption The electricity is small, the adjustment performance is good, and there is no punching phenomenon. The vibrating feeder has simple structure, reliable operation, convenient adjustment and installation, light weight, small size, convenient maintenance, and can prevent dust pollution when adopting a closed structure body.
