Basic Installation Notes of YA Circular Vibrating Screen

Basic Installation Notes of YA Circular Vibrating Screen

1.Please refer to installation drwawing to make concrete foundation before installing YA circular vibrating screen. Also please control plainness error within 3mm when foundation bolts or steel plate is embedded. 

2.It must inspect all springs after having installed the vibrating screen and make sure that every supporting position is under uniform stress. What’s more, please make sure that axis of motor should be lower axis of vibrator in 3-5mm.

3.Please make sure that all parts of vibrating screen should be connected firmly and all bolts should be fastened again before operating machine.

4.It can adjust exciting force by adjusting the intersection angle of eccentric block, thus it can adjust amplitude of vibrating screen.

5.Distance between vibrating screen and other obstacles should be more than 100mm.

YA Circular Vibrating Screen:6 Points to Tell You How to Maintain it

YA Circular Vibrating Screen:6 Points to Tell You How to Maintain it

1.It must inspect whether all fastening bolts are loose or not before operating YA circular vibrating screen.

2.It should be 4-6 hours for non-load running to make sure that screen boday keeps smooth. And the temperature of vibrator bearing is no more than 75℃.

3.It must tighten all bolts again after having non-load running.

4.Make sure that circular vibrating screen runs normal, it’s better to inspect fixture condition of the bolts regularly.

5.Inspect wearing parts frequently and change the worn or inelastic damping springs in time. The djustment, application and maintenance of vibration source should refer to vibration source specification.

6.After having stopped feeding materials and ensured all the materials are discharged, operator can turn off the machine.

Using Literature of Vibration Platform

Using Literature of Vibration Platform

Literature

1.What users do first before vibration platform is installed is that the foundation should be prepared.Also, the fixed bolts must be tight. 

2.It’s better to have a trial run for 3-5min and then stop it before all installation works have been done. After that, users should inspect all fixed bolts to confirm whether they are loose.

3.Users should usually inspect vibrator bearing and change lubricating oil at fixed period to let the vibrator bearing keep a better status.

Operation Specification

1.Before vibration platform is put into use, it should be no-load running for 3-5min for 2-3times and then it can be used officially.

2.If users find that there is some abnormal noise, the machine should be stopped and then inspect whether the fixed bolts are loose. If necessary, users can inspect whether the spare parts is damaged.

3.After all works have been done, operator should turn off power source and clean the surface of vibration platform.

 

What Will Happen During Ultrasonic Vibration Sieve Screens Tin Powder

What Will Happen During Ultrasonic Vibration Sieve Screens Tin Powder

1.If users find working efficiency of ultrasonic vibration sieve is low, it’s better to inspect the effect of acoustic. If the acoustic quality of ultrasonic vibration sieve is not so good, it will block mesh.

2.There are different sizes in tin powder. If users find this problem, it’s better to inspect mesh firstly. Pore diameter is different or mesh is damaged, it will cause uneven powder sizes. So users had better choose high quality mesh in standard manufacturers.

 

3.Oxygen content of screened tin powder is out of standard. If users find this problem, it maybe caused by poor sealing. Therefore, it’s better to check sealing ring to see whether the sealing condition is qualified especially during summertime.

4.If working status of ultrasonic vibration sieve is instability, it maybe make mesh heated and blocked. So it’s better to select proper vibration motor power and inspect the flexibility of equipment adjusted. 

From the points listed, do you think it’s hard to screen tin powder? Don’t worry. PK Machinery will help you solve these problems and select the most appropriate vibrating screen. If you have any interest, please contact us or visit our website:www.pkmachinery.com

Know About Shaft and Shaftless Trommel Screen

Know About Shaft and Shaftless Trommel Screen

Trommel can be divided into two types, one has shaft, another without shaft. According to different materials or real working environment, it’s better to choose the appropriate one.

Trommel screen without shaft:

In general, screen is installed in a horizontal angle. The drum can be driven by motor wheel gear or chain wheel. The rotation speed is slow and length of trommel screen is long so that material can be screened totally. Shaftless trommel screen can be installed cutting tool so that can tear up household garbage and other plastic bag. Generally, shaftless tromme screen is widely used to screen materials with small density, such as wooden chips, rubbish, activated carbon, fertilizer, chemical material and so on. 

Trommel screen with shaft:

Generally speaking, the device is installed on the frame in a inclined angle. When the materials are fed into the device, due to inclination and rotation of drum device, materials on the surface will rotate. In this situation, qualified materials will be discharge from outlet of bottom hopper while unqualified materials will be discharge from outlet of tail drum. Generally, it is widely used to screen material with large density, such as sand, coal,limestone and so on.

Necessity of Installing Hopper on Conveying and Screening Equipment

Necessity of Installing Hopper on Conveying and Screening Equipment

Are you worried about the bearing capacity of your equipment? Today, PK Machinery will give you some useful advice.

Whether users adopt vibrating screen or belt conveyor, once those equipmrnt work with other facilities, it’s very important to choose proper equipment to joint them. Generally, it’s better to choose hopper as connection device, because it can not only reserve material, but also reduce the impact force to screen mesh when feeding material so that can prolong the lifespan of device. 

For instance, one of our customer ordered inclined screw conveyor, due to its small capacity and it is needed to feed material directly, so our engineers suggest that it’s better to lay out one set hopper on screw conveyor. In this way can it not only reserve material to make screw conveyor work continuously, but also increase the working efficiency.

With the purpose of improving the production efficiency, it’s necessary to install hopper above the conveyor equipment or vibrating screen. Thus, it can reduce the cost of production line and save costs.

Distinguish Ultrasonic Vibration Sieve From Ordinary Rotary Vibrating Screen

Distinguish Ultrasonic Vibration Sieve From Ordinary Rotary Vibrating Screen

Ultrasonic vibration sieve is equipped with a ultrasonic generator that can prevent blockage. Specially, it is suitable for screening light specific gravity materials or fine powder. Generally, ultrasonic screening system consists of oscillator, ultrasonic resonant power supply and resonance ring. The high-frequency vibration which is generated by ultrasonic resonant power supply will change into high-frequency longitudinal oscillation wave through oscillator. This vibration will be spread to resonance ring to make it sympathetic vibration, and then this kind of vibration will be transmitted to the screen mesh evenly through the resonance ring.

Ultrasonic vibrating screen can separate all kinds of powder, enen though the powder is hard screened. In general, ordinary rotary vibrating screen cannot do this. Ultra-fine powder will be effected by large ultrasonic acceleration through mechanical wave which is attached on screen mesh. Generally speaking, compared with ordinary rotary vibrating screen, the passing rate generated by ultrasonic vibrating screen will be increased by 50%-400%. Mainly performances are as follows:

1. Reduce time of cleaning mesh.
2. Doesn’t pollute to powder which is generated by bouncing ball and other auxiliary materials.
3. Reduce screening frequency, keep high precision screening.
