How to Control Raymond Mill Feeding System

It is very important to control Raymond mill feeding system, which is related to efficiency and particle size. Our company engineer summarizes the control and automatic feeding tuning method.

Raymond mill feed adopts electrimagnetic vibrating feeding methods. Electric vibrator is a two-particle orientation forced vibration systems. By tank, connecting fork, armature components. Entire electric vibrator feeder should be a free state hanging around there should be a gap of swimming, without touching the material and feeder to avoid noise at work. After installation, the connection should be used to locate the fork and loosen the screws seized when (in the top three of the vibrator part, below one), will loosen and tighten the lock nut.

Open the vibrator back cover, check the core and the armature air gap is within the range of 1.8 ~ 2.1mm, are parallel and clean and check all the screws loose phenomenon, especially with the armature core compression screw and plate spring, everything is normal after the back cover.
Powered no-load test, adjust potentiometer, slowly and gradually increase by a small, adjustable amplitude, observed changes in the amplitude and current amplitude at 1.75-7%, the current in 0.6 ~ 2.5A, continuous watch over 1h current amplitude The stability of each part without loosening the screws.
In all normal circumstances, open the gate for material transport silo observed amplitude again (amplitude allow open hopper drop 0.5mm, such as falling too shall electric vibrating feeder trough manual inspection and adjustment of the elastic ballast system ) and the current is stable, the feeding amount meets the requirements. Such as amplitude and current ratings are in, if the feeding amount yet to meet requirements, lifting the vibrator into a downward inclination, so as to meet the requirements for quantity, but the maximum inclination (angle between the horizontal trough) not more than 20 degrees.
