GF Vibrating Feeder is the grizzly feeder driven by the vibrating motor. As an efficient primary feeder, it is specially designed for mobile crushing stations (also known as mobile crushers), semi-fixed crushing lines and small stock ground (Usually, the capacity is below 250TPH and the available volume of material silo is below 30m.) It is suitable to feed materials into jaw crushers, primary impact crushers and hammer crushers, etc.. Sometimes, it functions as a primary conveyor.

G-force is a key index testifying the performance of vibrating machines. The bigger the vibration strength is, the higher the capacity would be. GF Vibrating Feeder adopts advanced design theories and manufacturing technologies. Its biggest vibration strength reaches 4.0G and its capacity is 20% higher than traditional TSW Feeder.

GF Vibrating Feeder adopts a drop structure composed of two layers of grizzly bars, which can effectively screen out fine materials whose size is smaller than that of CSS (or tight-edge discharge port) because of double screenings. The removal rate of fine materials can be as high as 90%, greatly reducing the burden of primary crushers.

GF Vibrating Feeder takes vibrating motor as the vibration source. Users can control vibration force by adjusting the vibrating motor according to actual needs. The operation is quite easy, convenient and stable.

Compared with traditional metal spring, the rubber spring GF Vibrating Feeder adopts owns higher holding capacity and longer service life. Besides, the whole operation is characterized by high stability, low noise and little shock to the foundation.

GF Vibrating Feeder is mainly driven by vibrating motor, which can force materials to move slowly towards the discharge end under the action of vibration. During which, because of the gap between grizzly bars, various sizes of materials will be separated primarily so that the granularity can be more balanced. Generally, there is a bar grizzly at the discharge end of the feeder which can screen out materials finer than the gap between bars and send large materials into the crusher. The feeder is installed on the support which is equipped with the rubber spring to hold vibration of the feeder. Feeding refers to convey materials as required. By regulating exciting force of the vibrating motor, the feeding volume can be controlled. The lower layer of grizzly bars under the feeder can screen materials once more.

Iron ore dressing, according to the type and nature of ore, can have a variety of different processes. Concentrator generally used coarse crushing, middle crushing and fine crushing three stage. In the iron ore crushing production line, in order to improve the production efficiency of iron ore crusher, reduce production costs, often need to break iron ore as much fine as possible, the iron ore should crush to the small particle size, in order to achieve more crushing less grinding. After the practical experience of iron ore processing and user feedback, the industry believes that iron ore crushing with the cone crusher. Iron ore crushing production line specific process: iron ore by the vibrating feeder evenly sent to the iron ore crusher jaw crusher for coarse crushing, after the material from the tape conveyor into the cone crusher for further crushing, The crushed material is conveyed to the vibrating screen for sieving. The material required to reach the finished product size is conveyed to the finished product pile through the tape conveyor. The material that does not meet the required granularity of the finished product is returned from the vibrating screen to the crushing or crushing of the crater to form a closed loop The Iron ore crusher finished product size can be combined and graded according to the needs of users.

Our company mainly manufactures equipment for stone production line, such as XHP multi-cylinder hydraulic cone crusher, jaw crusher, impact crusher, Symons cone crusher, spring cone crusher, sand making machine, vibrating feeder, vibrating screen etc., which have been exported to more than 30 countries.

Symons Cone Crusher, the rotating forces of movable cone and eccentric shaft are at different sides of machine central line, while in Multi-Cylinder Hydraulic Cone Crusher, the forces are at same side. In this way, the rotating speed increases about 50% than the same specification Symons Cone Crusher. This is a milestone innovation, especially because the rotating speed of eccentric shaft increase, and the movable cone rotate speed also increase, thus the times of stone being crushed in cavity increase, which makes it possible to get laminate crushing. Percentage of fine material becomes more and the grade is more even, and more cubic aggregate.

vibrating feeder

Vibratory feeders are used in gravimetric feeding systems to handle solids with particles that are loo large to be handled by screw, rotary-vane, or vertical-gate feeders, or in operations where the physical characteristics of the solid particles would be adversely affected by passage through these volumetric feeding devices. The discharge flow pattern of a vibrating feeder is extremely smooth and thus is ideal for continuous weighing in solids flow metering applications.

The vibratory feeder consists of a feed chute (which may be an open pan or closed tube) that is moved back and forth by the oscillating armature of an electromagnetic driver. The flow rate of the solids can be controlled by adjusting the current input into the electromagnetic driver of the feeder.

The vibratory feed chute can be jacketed for heating or cooling, and the tubular chutes can be made dust-tight by flexible connections at both ends. The vibratory feeders can resist flooding (liquid-like flow) and are available for capacity ranges from ounces to tons per hour.

The Electric Vibratory Feeder is a vibratorthat provides an extremely efficient, simple and economical solution to the problem of making the most stubborn material flow freely. No longer need there be a sticking together of wet ore in the ore bin, or the arching over and hanging up of materials in hoppers and chutes with resulting lowered operating efficiency.

The powerful vibration of the simple, electro-magnetic vibrator is controlled by a separate, wall-mounted Controller, which is furnished with each vibrator. The dial rheostat in the controller varies the power of vibration. By merely turning the manual dial rheostat the power of vibration can be turned down to provide the most effective vibration required for the purpose. The controller is in a separate, dust-proof housing, arranged for wall-mounting at any desirable distance away from the vibrating mechanism attached to the bin, hopper, or chute.

These vibrators are furnished in many different sizes. Units are available that range from those equipped to handle large tonnages in ore bins down to the small noiseless model best suited to be attached to a dry reagent feeder. Reagent feeder applications are numerous, but a well-known use is where the vibrator is utilized to keep moist lime or soda-ash stirred up and flowing evenly.

In an ore bin with a flat bottom and a center discharge, the material, especially when wet, will build up in the corners and form a dead storage space just inside the walls of the bin. One or two vibrators mounted on the outside of the ore bin (opposite to each other, when two are used), will eliminate the work that otherwise frequently has to be done by hand with a pick and shovel. Another, and possibly more important aspect, is that maximum treatment efficiency is assured by an even feed to crushers or ball mills.

These vibrators are also available at extra cost with totally-enclosed explosion-proof, or water and dust-proof cases. Also, for special jobs where danger of explosion or fire exists, a water or air-pressure vibrator can be furnished. A major advantage of these hydraulic vibrators over electricvibrators is that they can be made to run at a slow speed as well as at a high speed (2400 to 4800 vibrations per minute).

The flow velocity depends on the method for loading the feederis it fed through a hopper? The velocity is also dependent on the material characteristics, size distribution and moisture content, as well as the slope of the feeder. The only way to determine the value for v is by actual observation and then the feeding rate may vary considerably.

Feeders are used to provide and control the flow of bulk solids to the process from storage units, such as bins, bunkers, silos, and hoppers. In to-days fully instrumented process plants, it is mandatory that feeders maintain a uniform flow of material at the rate set by signals from process equipment farther downstream in the flow. Large variations in feed, due to feeder blocking, arching or ratholing in the bin, may completely defeat the purpose of such a sophisticated control system with all its planned advantages to the process.

Most of the bins used in the mining and metallurgical industry to-day are of the plug flow type, as they are suited for the storage of hard, abrasive or coarse materials. Exceptions are the ore concentrate or fine powder bins which usually are of the mass flow type.

Plug flow occurs in bins or hoppers with flat sloping walls and is characterized by the flow of solids in a vertical channel extending upward from the bin outlet. Plug-flow bins are suited for solids which are free flowing, do not deteriorate with time and in which segregation is of no importance. As flow does not occur at the bin walls, this type of bin is useful for the storage of hard and abrasive materials. The drawbacks of this type of flow, however, are as follows:-

a) The live bin capacity of the bin is drastically reduced. b) The bin is not self-cleaning and usually cannot be emptied by gravity flow. c) Materials which deteriorate with time cannot be stored in this type of bin. d) The flow is erratic and non-uniform, as solids flowing through a vertical channel with a constant cross section tend to form arches which collapse and compact the material below, thus causing arching again. e) This type of flow pattern in the bin aggravates the segregation of particle sizes.

In many instances, hopper openings are large enough to prevent arching: however if the hopper is not designed for mass flow, piping or ratholing may occur. In plug flow bins, the material flows in the centre of the bin, into which the sides slough as the material is drawn from the bin. Reaching a certain level in the bin where the material has time to consolidate, sloughing will cease and a steady channel or rathole (limited flow) will form, drastically reducing the bins live capacity. In mass flow bins, channelling can also occur if the feeder does not draw the material uniformly across the whole area of the feed opening.

To overcome flow problems, flow-promoting devices such as external vibrators, pneumatic air panels, air jets and vibrating internal structures are usually installed. These relatively inexpensive devices can solve the problem in marginal cases. However, where the costly complete re-design of bins or hoppers is indicated by bulk solids flow calculations, other apparently less costly ways for improvement are usually sought.

The extension of the mine workings under adjacent lakes for the reach of the recently found copper ore body, and the introduction of sand fill underground in the past years using the mill tailings, led to build-up of the moisture content of the fine ore. In the meantime, the 50% increase of daily mill output from the original 2000 to 3000 tons necessitated finer fourth stage crushing and the addition of an extra grinding mill. The fine ore actual handled to-day is a roll-crusher product of -5/32 in size with a moisture content of 2% to 3%.

The fine ore bin, as originally conceived with its wear angles on the sloped walls, is of the plug-flow type. It performed satisfactorily in the earlier stages of operation of the plant when the material handled was coarser and lower in moisture content. With increasing ore moisture and material fineness, however, the live capacity of the fine ore bin was gradually reduced to a point where, in some instances, only channelling or ratholing occurred over the feed openings.

After visiting installations using long belt feeders, consideration was given to the use of the existing gathering conveyors as belt feeders. This scheme involved the cutting of long slots into the bin bottom above the entire length of the existing belts.

The flow pattern in a flat bottom bin with single or multiple openings is usually of the plug-flow type. The drawbacks of this type of flow have been explained previously. It was felt, however, by the author that improvements could be made by the appropriate location of feed openings and by the use of suitable feeders. The basic idea for this improvement was initiated by the review of the results of model tests performed on flat bottom bins, which indicate a mass flow type of pattern at the beginning of the bin discharge. This pattern switches gradually to plug flow as the material level drops below a certain point. This partial mass flow situation can prevail only if the material handled is reasonably free-flowing, the feed openings are sufficiently closely spaced, and the material is drawn uniformly from each opening.

The example illustrated is taken from an iron ore concentrator, and shows the arrangement in which the mill feed conveyor is receiving material from the gathering belt located underneath the two silos. The fine ore handled is taconite, -5/8 in size, and a tertiary cone crusher product with 1 to 2% moisture.

When drawn empty, the dead material left in the bin generally takes the form of a wedge-shaped hopper. However, the slope of the material should not be mistaken for the angle of repose , as it is really the included half angle e of the flow channel, which is usually much steeper due to material consolidation. Approximate expected values of e can be calculated knowing the flow properties of the material handled.
