Analyze the Design and Features of Vibrating Grizzly Feeder

Vibrating feeder is also named Vibratory feeder or vibrating grizzly feeder. Vibrating feeder is used to transfer the large size materials and granular materials from hopper to receiving device uniformly, periodically and continuously, also to screen the materials in the sandstone production line. It is widely used to match the crushing and sieving equipments in many industries including metallurgy, coal mine, mineral dressing, building material, chemical, grinding, etc.

Vibration grizzly feeder mainly adopts a pair of motors as the vibration source, which has the completely same performance and parameters. When these two vibration motors rotate reversely at the same angular speed, the inertia forces produced by their eccentric blocks will overlap or counteract each other at a special phase. Thus, a huge resultant vibration exciting force will be generated so that the machine body will be forced to vibrate on the bearing spring. This vibration is used as the power to make the material slide on the material chute and drop so that the material moves forward continuously. As a result, material feeding purpose is realized. When the material passes the screen bars of the chute body, smaller pieces of material will drop from the gaps between the screen bars and not enter the next breaking procedure. In this way, material screening result is achieved.

Features of Vibrating Grizzly Feeder:

1. Change and control material flow at anytime, easy to operate; Eccentric block is vibration source, low noise, low power consumption, regular performance,without material clash phenomenon.

2. Eccentric block rotates to generate the centrifugal force, makes the screening compartment and the vibrator continuous circular or approximately circular movement.

3. Simple structure, stable vibration, uniform feeding, continuous good performance, adjustable excitation force.

4. Materials are thrown continuously along the screen and are sent to the discharging port.
