|You can find two types: open sort and closed type. In accordance with the installation method, it usually is divided into hanging form and desktop type. That electromagnetic vibrating feeder possesses simple structure, convenient functioning, no need for lubrication, and also low power consumption; it can evenly adjust how much ore; therefore, it has been widely used. Generally made use of for loose materials. According to the performance requirements of the equipment, the pressure of the material on the tank must be minimized during the configuration design and style. According to the requirements with the manufacturer, the effective discharge with the warehouse material shall not be more than one-fourth of the aquarium width, and the material flow rate should be controlled at 6-18m/min. For materials using a large feed volume, a block board with sufficient height should be installed end of it of the silo; in order not to affect the performance in the feeder, the block board shouldn't be fixed on the tank. 
The electromagnetic vibration feeder is especially divided into linear trough reciprocating style (referred to as instantly trough type) magnetic vibration feeder basic structure through the structure
Two types, spiral trough twisting type (disc form for short), their working principles are basically a similar. The straight trough type is mostly used for feeding powder and granular materials that don't require directional finishing, or an operating machine helpful to clean, screen, dry, temperature or cool the elements; the disc type is generally used for materials that require directional finishing The feeding material is mostly used in the transfer of materials with a certain shape and dimensions. The structure is established in Figure 1, that is mainly composed of any trough, an electromagnetic exciter, along with a shock absorber. The exciter is composed of an electromagnet (iron main and coil), an armature, as well as a main vibration spring installed between each. It is the excitation reference for vibration. The work with the exciter can be controlled by a certain control device.
The electromagnetic vibrating feeder is really a relatively complete elastic program with two-point directional pressured vibration. The entire system works in a low critical resonance point out. The electromagnetic exciter is mainly used to drive the actual tank to reciprocate and vibrate with a certain inclination to move the material down the tank..Figure 2 (a) shows the working principle on the electromagnetic vibrating feeder. The material 2 is placed on the feeding aquarium body 1 supported by the main vibration spring A FEW, the armature 4 is of the main vibration spring from the tank body overall, and the coil 6 is wound to the iron core 5. Since one-way pulsating current soon after half-wave rectification flows with the coil, the electromagnet produces the corresponding pulse electromagnetic push (Figure 2(b)). In the positive half cycle from the alternating current, the pulsating current flows from the coil, generating a pulsating electromagnetic fascination between the iron core plus the armature, which causes the trough body go backward, and the main spring on the exciter deforms and shops potential energy; in your negative half cycle, You don't have current through the coil, the actual electromagnetic force disappears, as well as the armature separates from that electromagnet under the action from the spring force, so that this trough moves forward, so that the trough continuously vibrates forwards and backwards at the frequency with the AC power supply. 1) The electrical control with the electromagnetic vibrating feeder adopts the half-wave rectifier circuit, which will adjust the feeding total steplessly, and can be used in the automatic control production process to realize the automation of the actual production process.
2) Zero rotating parts, no lubrication, straightforward structure and convenient servicing.
3) The material from the electromagnetic vibration feeder is definitely micro-throwing motion, and the actual trough wear is smaller.
4) The electromagnetic vibrating feeder implement a trough made of suitable plates, which is suitable for conveying materials having severe high temperature have on and corrosiveness.
(1) Electromagnetic vibrating feeders are generally installed in suspension. The boom should be installed on a system with sufficient rigidity. So that they can reduce the lateral swing on the electromagnetic vibrating feeder, the suspension boom should be opened about 10° facing outward. For large feeders, as a way to facilitate maintenance and replacement from the trough, a movable carriage also need to be provided.
(2) The electromagnetic shaking feeder should be installed as one. Generally, disassembly is banned, and any rigid accessories will not be allowed to be consolidated to the machine. When installing, leave some space around the equipment in order to avoid collision with other gear during work. Generally, the minimum space in the length direction is 50 mm and also the width direction is 25 mm.
(3) The tank body from the electromagnetic vibrating feeder is usually installed horizontally or tilted. Its feeding capacity is proportional for the downward tilt angle, but too large the downward tilt angle will easily cause the materials to flow by itself and it is difficult to ensure the particular feeding accuracy. Therefore, it really should be determined whether to tilt upward, downward, or horizontally according to the nature of the particular material.
(4) After setting up, the feeder should be in a horizontal state to reduce the material from shifting to one side when the feeder can be working, and ensure every one fastening bolts are agency and tight.
1) Regularly check the feeding trough amplitude as well as coil current, and pay attention to whether the sound belonging to the machine is normal. If the sound all of a sudden becomes louder or it comes with an impact sound, analyze the reason carefully and stop the device immediately.
(2) The air difference between the iron core as well as armature must be balanced presenting notice. Check whether the bolts are loose and whether the gap is normal without notice. If the plate spring tightening bolts are loose or the plate planting season breaks, the air gap in between the iron core and the armature changes. Or influence, deal with it quickly.
(3) Frequently check regardless of whether the hoisting device can be loose. If the hoisting unit is loose, the four corners in the electromagnetic vibration feeder might be unbalanced, which will affect the feeding quality, therefore it should be tightened promptly.
(4) The sealing cover of the vibrator must be covered to forestall dust from entering, preventing the gap between your leaf springs, and cleaning the dust accumulation on the sealing cover frequently.
Being a feeding device before good crushing, generally disc feeders are widely used in raw material crushing process systems. However, this disc feeder has focused material drop points, critical wear, more material leakage, and heavy maintenance investment while in the later stage, which likewise brings great difficulties to help environmental governance. Based on my many years of experience, the use connected with electromagnetic vibration feeder will be more stable. Taking into account the special places the location where the raw material is crushed and also the material is dusty, that closed GZF type is definitely more suitable. The electromagnetic vibrating feeder has this particular characteristics:
(1) Strong vibration plus high efficiency;
(2) A reduced amount of power consumption per mass of material;
(3) Sometimes feeding and simple procedure;
(4) Simple structure, sturdy and durable, convenient and also quick maintenance;
(5) Good and reliable, low disturbance, long life, stable vibration design.
Relatively speaking, the production cost from the disc feeder is much higher than that of that electromagnetic vibration feeder, and also the maintenance amount is likewise greater. In the uncooked material crushing process, the electromagnetic vibrating feeder develops slowly with the impact of the on-site managing environment, investment environment and raw material properties. With the continuous deepening of economy fine management work, the necessary paperwork of electromagnetic vibrating feeder inside raw material crushing process features a broad space. Compared with the disk feeder, the application case with electromagnetic vibrating feeder has higher efficiency even more stable performance, which enormously improves the working surroundings and reduces the following investment.
