How to choose the suitable vibration motor for the vibration machine?

Vibration motor has many types and models with a wide application,it is usually applied with the feeder, vibrating screen combination. The vibration motor is very important in the vibration machine. It directly determines the working efficiency of the vibration machine.The vibration mechanical vibration motor selection steps are as follows:
A.According to the operating requirements, confirm the required vibration of the frequency (r/min) and the amplitude Ym (mm).
Such as the six vibration motor (n=960r /min) can drive the vibration chute, vibration feeder, vibration mill, vibrating screen etc.
B.According to the structure of the vibration machine itself, get the vibration weight G (kg) and calculate the required vibration force Fm (N) .
C.According to the vibration of the operation to get Fm, you can get the model of the vibration motor, please pay attention to the exciting force FH is larger than Fm.
D.Design the overall structure, and calculate the actual vibration parameters, after the calculation, if the vibration motor is too large or too small, motor model should be re-selected.
E.Design of vibration isolation system.

How to Analysis the Troubleshooting of Linear Vibrating Screen Plate?

Linear vibrating screen is a kind of vibrating screen. The linear vibrating screen can use exciting force generated by the vibration motor to realize the material accurate screening. At the same time its trajectory is linear, and has the advantages of simple structure, easy maintenance, high output and low energy consumption, which makes it is ideal for the assembly working line.

Screen plate is an important part in the linear vibrating screen, which directly affect the quality of the linear vibrating screen effect.
How to improve the life of the linear vibrating screen plate has become the key to reduce the failure rate of linear vibrating screen. Currently linear vibrating screen ribbed slabs are easily broken, and polyurethane material is easily worn. The main reason is that the screen plate joints place lack of no support beams, screen plate mounted directly on a straight beam, screen plate and vibrator are synchronized, which keeps linear vibrating screen ribbed slabs long time in the floating state movement, then the linear vibrating screen ribbed slabs are easily to broken. After the upper sieve broken, it will produce some > 30mm substandard ore, after the lower screen broken, the effusion pool will piled ore quickly, causing the whole scrubbing process have to stop, only after cleaning all the effusion pool can reproduction. Screen plate installed directly in the beam, which also caused polyurethane and steel directly contact. During the operation of linear vibrating screen polyurethane material easily worn, which will affect screen plate life.

Then we can use welding plate to support beam in the place of the screen joints, at the same time we can also add impact belt, and make the width of the belt is consistent with the beam width. By doing this we can reduce the wear and breakage of the screen plate during operation.

How do we deal with the Unbalance Motor Vibration Phenomenon of Vibration Table?

How  do we deal with the Unbalance Motor Vibration Phenomenon of Vibration Table?

In the process of the operation,Vibration motor may appear the unbalance vibration phenomenon.Unbalanced vibration motor, see this sentence, there are a lot of people would be confused, vibration motor is used to produce? What is the unbalanced vibration? Today, here, we will simply describe what are the cause of unbalance vibration motor vibration.

1.During using the vibration platform,a single vibration motor will arises the motor steering problems, the material will move in vibration platform surface.
2.Using two vibration motor will change the mesa vibration platform vibration uniform.Two motors due to counter rotating each other, each other offset the shaking force in central platform.

► Brief introduction:

Vibrating Feeder is a kind of linear direction feeding equipment, It consists of feed spout, vibration body, vibrating motor, damping device. It can feed material for belt conveyor, vibrating conveyor, bucket elevator, vibrating screen, crusher etc.

► Working principle:The feed process of the vibrating feeder is achieved by the feed spout do line reciprocating vibration periodically which is forced by the special vibrating motor. When the vertical component of the feed spout vibration accelerated speed is bigger than the gravitational acceleration, the material will be upthrow and jumping forward along a parabolic path. Because of the continuous exciting of the vibrating motor, the feed spout will
Vibrating continuously and the material in the feed spout will jumping forward continuously, so that achieves the purpose of feeding material.

► Features:
   1.Smooth operation, large feeding capacity with high efficiency.
   2.Low energy consumption.
   3.Characterized by even feeding, excellent continuity and adjustable vibrating force.
   4.Eccentric block as the main source of vibration.
   5.Double screening and embodies the functions of dirt removing, screening and feeding.

► Advantage:
      Stable vibration, reliable operation and long service life;
      The excitation force and materials quantity moving in the feeder can be adjusted conveniently and easily.
      The vibrating motor, as the excitation source, has low noise, small power consumption, good adjusting performance and without material splash.
      Simple structure, reliable running, convenient installation, light weight, small size, easy maintenance, and the enclosed type can prevent dust pollution.
► Application:
      ZG Vibrating Feeder is a kind of linear direction feeding equipment, which is widely used in pharmaceutical, automotive, electronic, food processing, packaging, glass, steel, construction, recycling, plastic industry etc.
 

► Operation and Maintenance:
      A.Problems occurring in Vibratory Feeders
Four basic malfunctions that bring attention to vibratory feeders need to be concern:
    1.Declining feed rate due to low amplitude. This will occur gradually over a period of time.
    2.A dead spot in the bowl – parts will not feed past a certain point in the bowl, even though they are moving elsewhere in the bowl.
    3.Intermittent operation. The feeder will spontaneously run at excessive amplitude or possibly no amplitude without apparent cause. Included in this category is for a feeder not to work at all.
    4.Noise from the vibrating feeder.

       B.Overhaul and Readjustment of Vibratory Feeders
   Here are the methods to solve the problems:
       1.Remove the bowl, and clean the mating surfaces between the bowl and the top casting of the base.
      These surfaces can accumulate dirt, sometimes, and other material that will make it difficult to draw the bowl tightly down on the top casting of the base. These surfaces should be flat and clean. Using emery paper or a flat file is adequate to recondition the surface.
      2.Operating on one bank of springs at a time, loosen the springs top and bottom and remove them.
      Both ends of each springs, as well as the spacers and mounting surfaces should be thoroughly cleaned with either emery paper, a wire brush or glass bead shot peened.
    3.Examine each spring for cracks and corrosion
The cracks will always occur adjacent to the hole punched in either end, on this type of spring. Sometimes these cracks are not visible to the naked eye, and a simple test is to hit the spring on something solid (dropping it on the floor). Usually this will cause the spring to break thru.
    - Any pitted springs or spaces should be replaced.
    - Reassemble the springs and spaces in the manner in which they were prior to disassembly.
    - Draw up the screw snug.
    - Do this on each remaining banks of springs.
