1. The electromagnetic vibration feeder is a device that is matched with the ball mill and used to evenly feed the ball mill. It mainly has the following characteristics:

(1) Uniform feeding, easy to adjust yield, and easy to achieve automatic control.

(2) This machine does not have rotating parts, is easy to maintain, does not require lubrication, and the material jumps forward in a parabolic shape in the trough, almost not sliding on the surface of the trough. Therefore, the wear of the trough is minimal, and no electric or reducer is needed during use. Due to the above reasons, this machine is fuel-efficient and has low maintenance costs.

(3) Can transport hot materials below 300 ° C.

(4) Sturdy structure, small size, light weight, easy installation and operation.

2. Before starting the electromagnetic vibration feeder, adjust the amplitude adjustment knob to the minimum position, sequentially connect the main power supply and control power supply, and then rotate the amplitude adjustment knob to gradually increase the amplitude to 7.5mm, at which point the current also reaches the rated value; It can also be adjusted to the learned amplitude and current according to the actual situation. In future use, this machine is allowed to start and stop directly with load at rated voltage.

3. The adjustment of the production volume of the feeder can generally be achieved through the following methods:

(1) Adjust the inclination angle of the feeder tank, but the maximum inclination angle should not exceed -20 °.

(2) Adjusting the opening of the silo or funnel gate can uniformly and continuously regulate the production volume.

(3) Changing the conduction angle of the thyristor rectifier can uniformly and continuously adjust the production volume.

4. During the operation of the feeder, attention should be paid to observing the stability of the current. If significant changes in the current are found, inspection must be carried out. The reasons for the current changes are generally as follows:

(1) The top screw of the spring plate has become loose after long-term operation.

(2) The spring plate has fractured.

(3) The size of the air gap between the iron core and the armature has changed.

At the same time, attention should be paid to whether there is a collision between the iron core and the armature. If there is indeed a collision sound, the vehicle should be stopped immediately.

5. The power supply voltage shall not exceed the rated value, and the current shall not exceed the given value in the technical performance table.
