What is a vibrating feeder?

The vibrating feeder is a kind of equipment that can uniformly, regularly, and continuously feed block and granular materials from the storage bin to the receiving device.

In the sand and gravel production line, the crushing machinery can be continuously and evenly fed, and the materials can be coarsely screened.

3 differences between an electromagnetic and motor vibrating feeder

There are essential differences between electromagnetic feeders and electric feeders. Do you know what the differences are?

Amplitude and frequency

Electromagnetic vibrating feeder

The motor vibrating feeder is a kind of inertial vibrating feed. The vibrating motor is used as the excitation source to drive the hopper to work. Amplitude: 2-5mm, frequency: 700-3000 times/min. The material is coarsely screened to improve the quality of the finished material.

Motor vibrating feeder

The electromagnetic vibrating feeder uses an electromagnetic vibrator as the vibration source to drive the hopper to work. It is characterized by a small amplitude of 1.5-3mm, high vibration frequency, up to 96~1450 times per minute, and mechanical and electrical integration. It is used for block, particle Quantitative, or continuous supply of granular or powdery materials.

Electromagnetic vibrating feeder

The electromagnetic vibrating feeder is a feeding device with an electromagnetic head as the vibration source. The vibration frequency is high, the amplitude is small, and the feeding amount is large, but it is not easy to maintain. If there is a problem with the electromagnetic head, the feeder may be disabled.

Motor vibrating feeder

The motor vibrating feeder is a feeding device with a vibrating motor as the vibration source. The vibration frequency is slightly lower than that of the electromagnetic vibrating feeder, but the amplitude is larger and the feeding amount is larger. The later maintenance is relatively simple. If there is a problem, it can be replaced directly Vibration motor will do!

The electromagnetic vibrating feeder uses an electromagnetic exciter to drive the tank body to vibrate back and forth under a certain inclination angle so that the material moves along the tank body. The material is placed on the feeding tank body supported by the main vibration spring, the armature is connected with the main vibration spring of the tank body, and the coil is wound on the iron core. The half-wave rectified unidirectional pulsating current flows through the coil, so the electromagnet generates a corresponding pulsed electromagnetic force. In the positive half cycle of the alternating current, the pulsating current flows through the coil, which generates a pulsating electromagnetic attraction between the iron core and the armature, which makes the slot body move backward, and the mainspring of the exciter is deformed to store potential energy; in the negative half cycle, the coil When there is no current passing through it, the electromagnetic force disappears, and the armature is separated from the electromagnet under the action of the spring force so that the trough moves forward so that the trough continuously reciprocates at the frequency of the AC power supply.

Motor vibrating feeder

The motor vibrating feeder is realized by using a vibrating motor or two motors to drive the exciter to drive the feeding trough to vibrate periodically in a straight line along the inclined direction. When the vertical component of the vibration acceleration of the feeding trough is greater than the acceleration of gravity, the material in the trough is Throwing up, and jumping forward according to the trajectory of the parabola, the throwing and falling are completed in an instant, due to the continuous excitation of the excitation source, the feeding trough vibrates continuously, and the coal in the trough continuously jumps forward to achieve the feeding effect. Purpose.

The above is the difference between the electromagnetic vibrating feeder and the motor vibrating feeder. I hope it can help you better distinguish the vibrating feeder and choose the vibrating feeder.
