Operation instructions of electromagnetic vibrating feeder
The electromagnetic vibrating feeder produced by ddd not only uses ore grinding, but also can effectively improve the working efficiency of the entire production line. It is your right choice.
1. The electromagnetic vibrating feeder is a supporting equipment for the ball mill. It is used to feed the ball mill evenly. The main features are as follows:
(1) The feeding is uniform, the output is easy to adjust, and it is easy to realize automatic control.
(2) This machine has no rotating parts, simple maintenance, no lubrication, the material in the trough is parabolic before jumping and advancing, almost not sliding on the trough surface, so the trough wear is small, and there is no need for electric and reducer in use. For the above reasons, this machine saves fuel and electricity, and the operation and maintenance costs are low.
(3) It can transport hot materials below 300°C.
(4) Sturdy structure, small size, light weight, easy installation and operation.
2. Before starting the electromagnetic vibrating feeder, adjust the amplitude adjustment knob to a smaller position, turn on the switchboard power supply and control power supply in sequence, and then turn the amplitude adjustment knob to gradually make the amplitude reach 7.5mm, and the current also reaches the rated value; It can also be adjusted to the learned amplitude and current according to the actual situation. In the future use, this machine is allowed to start and stop directly with load under the rated voltage.
3. The following methods can generally be used to adjust the output of the feeder:
(1) Adjust the inclination angle of the feeder tank, but the inclination angle does not exceed -20°.
(2) Adjusting the opening of the silo or hopper gate can adjust the production evenly and continuously.
(3) Changing the conduction angle of the thyristor rectifier can adjust the production uniformly and continuously.
4. During the operation of the feeder, you must pay attention to the stability of the current. If you find that the current fluctuates greatly, you must check it. The reasons for the current fluctuation are generally as follows:
(1) The jacking screw of the spring plate is loose after long-term operation.
(2) The spring plate is broken.
(3) The size of the air gap between the iron core and the armature has changed.
At the same time, you should also pay attention to whether the iron core and the armature collide. If there is a collision sound, you should stop immediately.
5. The power supply voltage must not exceed the rated value, and the current must not exceed the given value in the technical performance table.
