Vibrating feeder is also known as vibratory feeder. In the production process, the vibrating feeder can feed the massive and granular materials from storage hopper to the primary crusher or secondary crusher evenly, timely and continuously. In some production line, vibratory feeder or feeder machine, vibration feeder can evenly and timely feed raw materials for the crushing machines and do coarse screening of materials by grizzly bar, which is widely used in metallurgical, coal mine, ore dressing, building materials, chemical and other industries.
Working Principle of vibrating feeder:
The vibrating feeder is composed of a feeding trough, a vibration exciter, a spring support, and a transmission device. The vibration source of the vibrating feeding of the trough body is a vibration exciter or a motor. The vibration exciter is composed of two eccentric shafts (main and passive) and a gear pair. The motor drives the driving shaft through the V-belt, and then the gear on the driving shaft meshes The eccentric shaft rotates, and the main and eccentric shafts rotate in opposite directions at the same time, which makes the trough body vibrate, so that the material flows continuously and achieves the purpose of feeding the material.
- 1.Stable work performance, using vibrating motor or double eccentric shaft as the excitation source, the amplitude is stable, the continuity is good, the excitation force is adjustable;
- 2.Cost-effective, reduce the pressure of the back-end crushing and screening procedure, simple structure, strong and durable;
- 3.Easily to be controlled, frequency conversion motor as options, by adjusting the frequency, so as to change the capacity, easy to control the amount of feeding, no need to start the motor frequently.
