How to solve problem of damp material blockage occurs in vibrating screen ?

Vibrating screen is a kind of high precision and fine powder screening equipment, with the characteristics of low noise, high efficiency, small size and quick screen mesh replacement,it adopts fully enclosed structure which is suitable for particles, powder, liquid, etc. Clients ever said wet material blockage occurred in vibrating screen,here PK Machinery will list some suggestion,hope it is helpful.
1.Increase the excitation force of vibration motor and increase the amplitude.
2.Increase the vibration frequency, please use the high-frequency vibrating screen.
3.Diluted with water to increase the liquidity of material.
4.Replace the screen mesh regularly to avoid damp material blockage.
5.Manual work assisted cleaning up the screen mesh blockage.
6.Equip with cleaning device, such as the brush.
Hope above mentioned are workable, if you have the other problems about vibrating screen,welcome to contact us freely.

Why vibration sieve screen mesh damaged so fast?

Why vibration sieve screen mesh damaged so fast? Factors that quicken vibration sieve screen mesh damage are like screen mesh quality, screen mesh tensioning force, material feeding problems etc.In numerous factors,screen mesh quality is the key factors that aroused screen mesh damaged fast.Here we will introduce the each factor as follows.

Factors:
1.Screen mesh quality is an important factor that aroused screen mesh damaged fast. If the screen mesh material can’t meet with the requirement of the material sieve, then the screen mesh will damaged soon.
2.Screen mesh don’t have enough tension that caused the screen vibrate, in this case the screen mesh usually damaged or broken along the edging.
3.Generally speaking, screen mesh has an upper and a lower force layer, which request that the two layers contact closely. If the screen mesh pre-tensioning is poor, when the lower force layer is tension but the screen layer isn’t tension, then when the vibration sieve working the vibrating distance of the screen mesh is too long, can’t effective compress with the screen frame contact section, these is also one reason that aroused screen mesh damaged so fast.

4.Material feeding problem As we should keep feeding during the vibration sieve work process, if feeding too much one time will block the material normal movement on the screen plate, which not only easily make the screen mesh become loose but also will greatly reduce the capacity of the material. Feeding material too much one time will make the unbalanced motor loading suddenly increased, which not only easily damaged screen mesh but also easily caused the vibration motor damaged, so when we feeding material must feeding uniformity. If the feeding way has strong impact, the vibration sieve must equip with impact hopper. If the material impact the screen mesh will consume exciting force generated by the vibration source, which more likely to cause screen mesh damage and screen mesh fatigue.

Solutions:

1.When you choose the vibration sieve you should choose the quality reliable screen mesh

2.Check the tensioning force of the screen mesh usually

3.Check whether the screen mesh squeezing ramming or not

4.If you sieve liquid with strong impact, you’d better equip hopper or buffer.

5.If there is accumulation of material, you should find out the reason as soon as possible such as adjust the eccentric of vibration motor

The Mainly Tips for YA Circular Vibrating Screen

1.Before operating:Inspect the YA circular vibrating screen whether all fastening bolts are loose or not

2.During non-load running:Make sure that screen body keeps smooth and the temperature of vibrator bearing is no more than 75℃

3.After non-load running:Ensure tighten all bolts again

4.After running normal:Better to inspect fixture condition of the bolts regularly

5.During put into use:Inspect wearing parts frequently and change the worn or inelastic damping springs in time. The adjustment, application and maintenance of vibration source should refer to vibration source specification

6.Before stopping running:Stop feeding materials and ensured all the materials are discharged

Four Advantages of Linear Vibrating Screen with an Inclined Angle

Linear vibrating screen is widely used in mining, coal, refractory, metallurgy, building materials and other industries etc. PK Machinery can customized according to the client’s requirement and site space, such as the inlet and outlet location, vibrator motor installation location and linear vibrating screen can be inclined.
1. The motor angle of inclined linear vibrating screen can be adjusted freely, you can also enlarge the vibration source to get a amplitude which can meet the requirement of material screening.
2. The linear vibrating screen with an inclined angle can increase the screening production and improve production efficiency.
3. According to different material properties, the material can be sieved quickly due to the inclined angle of linear vibrating screen, it also can reduce the damage and friction of the screen mesh which brought by material.
4. When the angle is 15 °more than parallel, material are input as obtuse angle, it will increase the service life of the screen mesh effectively.
