How to Install the Circular Vibrating Screen Punching Mesh?

Screen meshes Includes manganese steel woven mesh screen, perforated plate, stainless steel sieve, etc., each of which has its own special place, and therefore it should be selected according to the actual situation.Here we will share some of the easy to implement tips to install the circular vibrating screen punching mesh.
Vibrating mesh sieve punching method of installation with slime mesh sieve dehydration installation is similar. Entire slime dewatering screen is horizontal assembled, but in order to ensure the dehydration effect of the machine, so the screen is negatively corner installation. Alternatively polyurethane screen mesh, tension mounted, or stainless steel weld seam sieve, pressing installation, to meet different needs. But the circular vibrating screen is angled, when using perforated screen, pressing need for the use of square wood, wedge tensioning way.

Insufficient tightness of the screen will cause the following effects:
① mesh bending deformation, stress concentration serious, relaxation is easy to produce secondary vibration sieve, sieve premature breakage under alternating stress, caused no small economic loss;
② bending deformation affecting mesh sieve through effective screening area, so this should be through the sieve through the sieve material failed, resulting in reduced screening efficiency;
③ screen surface depressions lead to material retention, hinder the forward movement of the material layer, and ultimately affect the productivity of the shaker.

In view of this, increasing the tension of the screen, to ensure smooth screen surface, not only can effectively improve screen life, but also help to ensure the efficiency and productivity of vibrating sieve.

Methods to Improve the Screening Efficiency of Vibrating Screen

For different ‪‎screening materials,the screening efficiency may different.In order to better sieving the materials,it is necessary to improve the screening efficiency of vibrating screen.Here,PK Machinery lists the methods which can really improve the sieving efficiency as follows.

vibrating screen

First of all,we will show you the two mainly tips.One is dry sieving,and the other is wet sieving.
For dry sieving, you should strictly control the feed water, when the water is high, then considering the screening ingredients.
For wet sieving,conditions permitting, this is the most effective means to improve the screening effect.

Then secondly,the following methods you also should pay attention to:
1.Selection with self-cleaning sieve sieve batter to reduce porosity, such as adding anti-clogging means spring rod sieve or screen below
2.Improve the sieve openings, high aperture ratio will help to improve the screening effect
3.When feeding, feeding along the full width of the screen to make full use of the screen surface
4.Reclining screening machine if conditions permit, the appropriate angle helps to reduce the material thickness, to achieve a thin layer of screening material
5.Counterweight adjustment method to improve the circular vibrating sieve effect

Factors should be Considered when Purchase a Vibrating Screen

First, the physical properties of the material to be sieved
Including material particle size, shape, moisture content, bulk density, and other material properties. When the particle size is very small, mesh is small, usually screening rate is very low, the same amount of processing need to use a larger model; when large humidity of materials, screening efficiency will be reduced, but the larger mesh size, moisture the impact is smaller; when the material is corrosive, usually made of stainless steel or stainless steel material contact parts.
Second, the nature and structure of the screen surface
If materials do vertical movement on the screen surface, it will have high screening rate and large capacity. For certain material, production rate and screening rate of vibrating screen are determined by mesh size. In general, wide screen surface has high production rate and long screen surface has high screening rate. What’s more, the larger the effective screening area is, the higher the screening rate is.

Third, the production conditions
When a large load screening machine, the low screening efficiency. Feeding uniformity of screening process significant, so try to achieve uniform feed (In this regard, our company specializes in plane rotary sieve inlet Added sub-feeder, can achieve uniform feed).
Only taking the above influence factors into consideration can users purchase the most economical and appropriate vibrating screen.More information, please visit www.pkmachinery.com

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 .

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 ℃.

vibrating screen apply to environmental or sewage treatment industry

There are many people questioning the processing capacity of vibrating screen in sewage treatment, however, we can see the vibrating screen plays an irreplaceable role in environmental industry and sewage industry as it can remove the municipal wastes, particles of heavy metals and fine particle pollutants in sewage effectively.

 

Paper-making industry:
Vibrating screen acts as a filter grid in the pre-treatment of industrial sewage which generated in paper-making industry, and effectively removed large particles of pollutants in wastewater.
Vibrating screen plays an important role in sewage treatment:
1. Sanitary sewage
With the improvement of life quality, the emission of sanitary sewage capacity is also continuously increasing. Although numerous municipal wastes are mixed in the sanitary sewage, vibrating screen has very good application in the pre-treatment of these municipal wastes. 
2. Sewage treatment plant
Sewage treatment plant disposes the sewage by passing through pre-treatment, primary and secondary treatment, advanced treatment and others. We have mentioned that it can play the main role in grid filtration in the pre-treatment process. Then we can utilize the exquisite vibrating screen to carry out fine filtration before sedimentation. This will not only shorten the settling time, but also improve the energy efficiency of the sewage treatment.
In summary, vibrating screen has obvious expression in the field of environmental protection and sewage treatment capacity and function. However, we have to understand that only the more meticulous manufacturing and improve the working efficiency of vibrating screen in all aspects, after that only we can more efficiently utilize these working performances and benefit features of vibrating screen.

How to Prolong the Life Span of Circular Vibrating Screen?

Circular vibrating screen is widely used for building materials, chemical, food, abrasives, plastic, medicine, chemical fertilizer, metallurgy, glass, food, ceramics etc.

The following are the methods to prolong the life span of circular vibrating screen which might give you some ideas during the operation: 

1.The bolts which connected with the body and screen box of circular vibrating screen are strength bolts. It cannot be replaced by using normal bolts to connect with the body and screen box. The fastening of bolts must be checked regularly, at least once a month. Loosen of bolts might occur if any bolt is loosen, which will cause damage to linear vibrating screen. 

2. The space between side plates and mesh sieve box must be equal during replacing the woven mesh. First of all, tighten up the flat steel in the middle. At the same time tighten the mesh surface tension and ensure the surface tension is uniform and constant. Then, slightly tap the mesh surface tension along the entire length by using a hammer to check the tension. One of the reasons for woven mesh to damage in shorter period is due to the tension, either not enough or uneven.

3. The temperature of bearing should not exceed 75°C during normal operation. This is because there is a running-in process of new vibrator which might cause the higher temperature, but the temperature will be stable after running for 8 hours. Check the standard, oil level and purity of oil if the temperature remains high.
