What Factors Influence the Speed of Vibrating Feeder

Vibrating feeder is one key machine used for conveying the raw material whose size is the cube to the feed inlet with the smooth speed.Feeder machine applied in the sand production line and stone production line can feed the raw material for the crushing machine and sand maker, which can be widely applied in the industries such as the sandstone producing, ore dressing, building material and the chemical industry. During the actual production, during the influence of friction and resistance, the actual cast start angle of materials in a vibrating feeder tends to lag behind the theory start angle, which means that the actual average velocity of material is less than the theoretical average velocity.

The properties of materials, friction lag angle and the actual average velocity are closely related. However, due to the lack of experimental data accurately, so that the material properties of different vibrating feeder and the actual average velocity influence coefficient so far are not an accurate figure. Therefore, the influence coefficient should be 0.8~0.9 cm; the shape of granule material 0.9~1.0cm; while for powder materials is 0.6~0.7cm. When the vibrating feeder conveys granular coal, it should be 0.9~1.0cm.

When calculate average transport velocity of material in the sliding motion and throwing motion state, we only need to consider the thin material layer, without considering the influence of the average velocity. In fact, if the material layer is thicker, the actual average speed of vibrating feeder is smaller than the theoretical average velocity. We also found that for the massive and granular materials, the actual average velocity is affected by the thickness of material layer, which is relatively small. The powdery material is affected by the relatively large impact, however, some powder material is on the contrary, when the material layer thickness increases to a certain degree, the average speed of its actual delivery will increase rapidly, and this phenomenon is mainly due to the increase of material layers so as to form the flow of material layer.

At the present, Fote Heavy Machinery has set up three state level machinery research institutes, and we also produce various kinds of vibration feeder, swing feeder and free service for assembling various kinds of production line.
