Introduction of vibrating feeder.

Vibrating feeders are also known as vibrating feeders. In the production process, the vibrating feeder can uniformly, regularly and continuously feed the block and granular materials from the storage bin to the receiving device, and can feed the machinery continuously and evenly in the sand and gravel production line, and carry out coarse screening of the materials, which is widely used in the crushing and screening combined equipment of metallurgy, coal mine, mineral processing, building materials, chemical industry, abrasives and other industries.

Features of the vibrating feeder:

Stable vibration, reliable work and long life; The excitation force can be adjusted, and the flow rate can be changed and controlled at any time, which is convenient and stable to adjust; The vibrating motor is the excitation source, with low noise, low power consumption, good adjustment performance and no punching phenomenon. The structure is simple, the operation is reliable, the adjustment and installation are convenient, the weight is light, the size is small, the maintenance is convenient, and the dust pollution can be prevented when the closed structure body is adopted.

Advantages of vibratory feeders.

1) Small size, light weight, simple structure, easy installation, no rotating parts without lubrication, easy maintenance, low operating cost. (2) Due to the resonance principle of mechanical vibration, the electromagnetic vibration feeder works in a low critical near-resonance state, so it consumes less electrical energy. (3) Because the material flow can be changed and opened and closed instantaneously, the feeding amount has high accuracy.

4) The control equipment of this series feeder adopts thyristor half-wave rectifier line, and can realize centralized control and automatic control of the production process. (5) Because the material in the feeding trough is continuously thrown up in the feeding process, and jumps forward according to the parabolic trajectory, the friction of the feeding trough is small. (6) This series feeder is not suitable for occasions with explosion-proof requirements.

7) Conditions for the use of electrical control devices: a. The altitude does not exceed 1000 meters. b. The temperature of the surrounding medium does not exceed the range of -20 +4.

c. When the temperature of the surrounding medium is 25, the relative humidity is not greater than 85. d. There is no serious corrosive medium around and affecting the electrical insulation performance.

Vibrating feeders are also known as vibrating feeders. In the production process, the vibrating feeder can uniformly, regularly and continuously feed the block and granular materials from the storage bin to the receiving device, and can feed the crushing machinery continuously and evenly in the sand and gravel production line, and carry out coarse screening of the materials, which is widely used in the crushing and screening combined equipment of metallurgy, coal mine, mineral processing, building materials, chemical industry, abrasives and other industries.

Vibratory feeders are one of the most common types of feeding equipment. It is a kind of equipment that can uniformly, regularly and continuously feed lumpy and granular materials from the storage bin to the receiving device. It is widely used in metallurgy, mining, coal, electric power, chemical industry, building materials, light industry and grain industries, and is matched with other equipment to realize feeding, feeding, batching, quantitative packaging and process automation operations.

The vibrating feeder is to feed the block and granular materials from the storage bin to the receiving device evenly, regularly and continuously to the crusher, pulverizer and other feeding, as well as for automatic batching, quantitative packaging, etc., and can be used to automatically control the process to realize the automation of the production process. Righteousness.

In the mining industry, Shandong China Coal Feeding Equipment is mainly used for uniform conveying and screening of large materials. Commonly used feeding equipment are: electromagnetic vibration feeder and motor vibration feeder.

The feeder has: stable vibration, reliable work, low noise, low energy consumption, no flushing phenomenon, long life, easy maintenance, light weight, small size, easy equipment adjustment and installation, good comprehensive performance, YMJT03 can prevent dust pollution when using a closed structure of the fuselage and many other advantages.

<>1. From the perspective of the characteristics of the material itself, the main reason for the blockage of the vibrating feeder is the large viscosity and moisture. Due to the reduction of material fluidity, this will lead to the usual phenomenon of "hanging on the wall" and "shed material" after the material enters the warehouse, especially in the rainy season.

2. During the shutdown of the vibrating feeder transportation system corresponding to the silo, due to the long storage time in the silo and the influence of humidity, the friction between the material and the silo wall increases, resulting in blockage.

3. There is too little material in the silo. Because the material falls from a height of more than ten meters, the deeper the depth of the vibrating feeder silo, the greater the acceleration, and the greater the impact, so the lumpy material gradually compacts the storage material at the bottom of the silo under the action of gravity; When the material is discharged again, there is a high risk of clogging.

4. Structural blockage. At present, the silos of vibrating feeders are made of steel plates, and their shapes are mostly cones, square cones or hyperbolic shapes with large upper mouth and small lower mouth. The material flows from top to bottom by its own weight in the warehouse, and the lower the flow section is, the smaller the cross-section, which is also an important reason for the blockage.

5. Poor management of material storage points leads to the failure of large pieces of materials or foreign objects into the warehouse. At the entrance of the silo of the vibrating feeder, the screen mouth that is not disturbed according to the requirements is too large, causing large materials or foreign objects to enter the silo and cause blockage.

Silo raw materials. 6. In the process of use, it should be noted that the load of the silo should not be directly pressed on the chute of the feeder, which will lead to fatigue damage to the spring plate and connecting fork for a long time, resulting in the fracture of one of them.

7. It may be caused by too much feeding, resulting in the accumulation of materials in the machine base, the increase of the force of the lifting resistance screw conveyor, and the poor operation of the hopper.

8. The gap between the core of the feeder and the armature is too large or too small. If this happens, it will affect the feeding of the feeder because the machine cannot reach the normal amplitude.

9. It may be caused by the incoordination between the various parts of the feeder, which is mainly caused by the loosening of some parts. This requires the tuning of the components to adjust the compression degree of the machine spring plate hold-down bolt to the best, so that the chute can reach the amplitude range specified in production.

Whether in the coal industry, metallurgical industry, chemical industry, power industry, in the process of material transfer and loading are inseparable from the vibration feeder, how to make your use of the feeder to extend the service life can be considered from the following aspects:

1.Install and use in the correct way.

2.The excitation force of the vibrating motor should be selected appropriately, too large is easy to damage the main parts, too small can not reach the required feeding amount.

3.The eccentric blocks at both ends of the vibrating motor should be adjusted consistently, and must be locked to prevent loosening during use.

4.The anchor bolts of the vibrating motor must be tightened, and they should be re-tightened after a period of use to ensure that they are not loosened, otherwise the main body will be damaged and noise will be generated.

5.After 500 hours of use, the bearing of the vibration motor should be filled with high-temperature resistant lithium oil.

6.For the double-mass vibrating material machine, the amplitude of the mold cover should be controlled, and it is best not to exceed 5mm.

7.During the use of the double-mass vibrating feeder and shear rubber spring, the heat dissipation gap between the rubber blocks should be cleaned and protected frequently to avoid mud and dust blockage, which will affect the heat dissipation effect.

8.The vibrating motor is heated in use and should be replaced in time.

9.The vibrating groove of the vibrating feeder should not be changed casually, heightened or lengthened.

Hello, we are happy to answer for you, in general, the vibrating feeder cannot be used directly for blanking. Vibratory feeder is a common powder and granular material conveying equipment, suitable for material conveying, metering and batching operations in various industrial fields. The principle is to transport the material out of the storage hopper by the inertial force generated by the vibration.

However, due to the design features and working principle of the vibrating feeder, the following problems may arise if it is used directly for blanking:1Unstable unstable unloading flow

Because the power output and amplitude changes of the vibrating feeder can affect the material flow, direct use for blanking may result in unstable flow that is difficult to control. 2.Material damage:

Because the vibrating feeder will produce **, collision and other materials during the conveying process, if it is directly used for blanking, it may cause starvation or deformation of the material before talking. Therefore, in practical applications, it is often necessary to use vibratory feeders in conjunction with other equipment, such as adding inlet and outlet valves or providing a drop height to effectively control and manage logistics.
