How to Deal With the General Common Faults of Gyratory Screen?

If Screen body running abnormally such as Sieve unusual sports such as torsional oscillation occurs etc, mainly due to eccentric rotors installed improperly result in main axle bend or bearing damage. For these reasons, you can make the appropriate adjustments.

If mixing occurs, the mainly reason may be screen damaged or screen body seal is lax, Solutions is to replace the screen cloth or fill holes, check the seal strip.

If the output can’t meet the requirement, mainly reasons are multiple: such as the material moisture is too high, mesh blockage, mesh size does not meet the requirements, the belt speed ratio is too low or belt occurs slip, lack of feed rate, bouncing balls serious wear and tear. Solutions is to reduce material moisture, replace screen cloth or change the screen clear network system, check the pulley and adjust the belt tension, increase feed rate, replacing the bouncing ball.

     
When support frame fracture happens, mainly due to the support frame has usage cycle, long-term implants uniform or long-term bearing torsional stresses make itself flexibility failure, then result in fracture. Therefore, in the routine maintenance, you should pay more attention to the condition of the support frame, checked found and replaced promptly, if possible, you’d better replace all the support plate at the same time, and try to make every support plate force uniform, so as to make it consistent with the amplitude .

Is The Driven Device Suitable For Linear Vibrating Screen?

Linear vibrating screen is designed with dual-vibration motor drive.According to the capacity of different material is different, the vibrating screen model and the vibration source is different also.Here PK Machinery would like to talk about the driven device selection for linear vibrating screen.
For some ceramics, food, and other less dense granular material, when dealing with a smaller amount, demand shaker model is small, usually less than the length of the screen surface 3000mm, width of the screen surface is less than equal to 1200mm, the small screen of its own weight , to meet the amount of processing conditions, the vibration source shaker select both synchronous and opposite vibration exciting force generated by the motor rotation direction. The motor can be installed on top of the screen box, bottom and sides.

Linear Vibrating Screen

For some coal, ore, building materials and other denser particulate material is too large, the environmental conditions, the general requirements of larger handling capacity, demand shaker models are also relatively large, usually larger than the screen surface length 3600mm, when the screen surface is greater than the width of 1500mm, the weight of the screen itself is also heavier. When the amount of processing required to achieve, you need to select running motor driven exciter excitation force generated as the vibration source, achieve grade materials. Exciter is usually installed above or below the screen box.
If conditions have space restrictions or special requirements, we also can make special optimized design.

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

How to Maintain Vibrating Screen in Summer

In summer, excess temperature is a hidden danger of daily operation for vibrating screen, generally speaking, working requirements of the environment temperature is not more than 40 ℃, so during the daily operation of vibrating screen, what we should concern about is not only the process of production, but also the degree of temperature that the vibrating screen can bear.

For the outdoor working conditions, a anti-sunshine net or cover should be set up for the vibrating screen.

Long-time sun exposure not only make the machine easy to get aging, but also cause the vibrating screen can not work normally due to the high temperature which will affect the screening efficiency and quality, it will even lead to a serious component damage, such as the damage of vibration motor.

For the indoor working condition or vibrating screen works in an ore processing plant, please pay attention to the adjustment of the indoor temperature, as well as the ventilation and the permeability, generally, a good working temperature is not more than 40 ℃.

The Development Trend of Vibrating Screen

Vibrating screen is widely used in mining, coal, smelting, building material, refractory material, light chemical, medicine, food etc..

With the higher and higher requirements, the development of vibrating screen reaches a new stage. Combining the domestic and abroad situation, it can be divided into some aspects as follows:
1.To develop in the direction of high efficiency and large output 
Development of industrial modernization process which increases enterprise scale and production capacity greatly, so it needs to match with an efficient high-throughput screening machine.
2.To develop in the direction of standardization, serialization and generalization 
This is a good way to guarantee the quality and reduce the cost , it also provides convenience for designing and organizing specialized production.

3.To develop in the direction of stronger vibration strength
The vibration of vibrating screen is strengthened gradually in order to improve productivity and screening efficiency.
4.To develop in the direction of light ,environmental protection and simply structure
Now the structure of vibrating screen is much more simple than previous one, it is more convenient to replace the screen mesh and will save a lot of time.
Henan plain mining machinery co., LTD is specialized in manufacturing screening equipment, lifting equipment and conveying equipment , with abundant engineering design experience, professional technical ability and strict fabricating specification, PK Machinery is always walking at the forefront of this developing trend!
