Best Quality HookStrip Flat Shaker Screen of DC Machinery

The hook strip shaker screen has many advantages. Due to the difference in mesh number of the screen meshes, the user can get more excellent screening effect by using the screen meshes with rational and correct arrangement.

hookstrip shaker screen

The metal lining is designed with different hole size to match with screen mesh of different mesh number. On the basis of ensuring adequate strength, we strive to obtain the maximum effective area of the screen mesh. Meanwhile, the integration of the bottom coarse wire mesh with small mesh number and metal lining enhances the strength of the whole product and prolongs its lifetime effectively.

Features of HookStrip Flat Shaker Screen of DC Machinery
Provides improved energy transfer from the shaker basket to the screen, thus faster solids separation
Improves screen life, thereby providing replacement cost savings and downtime minimization

How to improve shaker screen blinding

Screen blinding occurs when grains of solids being screened lodge in a screen hole. This often occurs when drilling fine sands, such as in the Gulf of Mexico. The following sequence is often observed during screen blinding:

screen

1. When a new screen is installed, the circulation drilling fluid falls through the screen in a short distance.
2. After a time, the fluid endpoint travels to the end of the shaker.
3. Once this occurs, the screens are changed to eliminate the rapid discharge of drilling mud off the end of shaer.
4. After the screens have been washed, fine grains of sand that lodged in the screen surface can be observed. The surface of the screen will resemble fine sandpaper because of the sand particles lodged in the opening.

Most screens used in the oil field is blinded to some extent by the time it needs replacing. For this reason, when the same shaker screen size is reinstalled, the fluid falls through the screen closer to the feed.

One common solution to screen blinding is to change to a finer or coarser screen than the one being blinded. This tactic is successfully if the sand that is being drilled has a narrow size distribution. Another solution is to change to a rectangular screen, although rectangular screens can also blind with multiple grains of sand. Unfortunately, the process of finding a screen size that will not blind is expensive.

Another solution is to change to a rectangular screen, although rectangular screens can also blind with multiple grains of sand. Unfortunately, the process of finding a screen size that will not blind is expensive.

In the late 1970s, the layered screen was introduced to avoid screen blinding. This hook strip screen was mounted on a downholl sloping, unbalanced elliptical motion shale shaker vibrating at 3600rpm. The two fine layers of screening cloth, supported at 4 inch  intervals, tended to dislodge fine grains of sand and would only blind about 25% in severe laboratory tests, leaving 75% of the screen unblinded. The non-blinding feature is assumed to be the result of the deceleration of the two screens. The wire diameter is in the range of 0.002 inch and the opening size are in the range of 0.004 inch.

Why shaker screen are easy broken

As we known shaker screen is a part of quick wear part of solid control system. But why it is so easy broken and how should we solve the problem?

The reason why excessively fast broken:

The quality of screen is not qualified, tension strength is not enough, vibration motor rotary direction is error, clay accumulation and etc.

shaker screen1 (2)

1 The tension strength is not enough lead to the screen vibrate, it usually retures along with the screen edge or package edge fracture place.

2. The quality of screen is not quality, usually screens has two layers, upper layer is the screening part and the bottom stress layer. We request the two layers should be fit closely, if the screen pre-tensioning technology is poor, when the bottom stress layer is tighten, but the screening layer is not tighten, the drilling cuttings throwing force is much reduced and can’t discharged when works.

shaker screen1 (1)

3.When adjust motor direction, the field operators according to the the experience of single-shaft shale shaker or the linear motion shale shaker think so long as drilling cuttings moving towards is ok, but the method don’t suitable for balance elliptical shale shaker. If the motor wrongly toward turn to the inside, although the throw angle is 45°, But there are cuttings Rolling back force, this time the speed of the forward migration of drilling cutting is much slower and stay a long times on screen, even will lead to drilling cuttings can’t discharged.

Compared to the product with metal back, our composite material shaker screen has lighter weight. Furthermore, it can be repaired easily. Due to the patented plug-repair system, the time for repairing the damage of the screen mesh is reduced largely and it only needs less than two minutes. When repairing the damaged screen mesh, there is no need for removing the damaged mesh as well as the processes of cutting, gluing and bonding the mesh. Only with a special plug can the problem of repairing the damaged mesh be solved.

Shale shaker screen manufacturer from china

Shale shaker screens  are important spare part for shale shaker. Even for general solids control equipments, shaker screen is rather consumable.

Shaker screen types will be divided into various types according to different standard.Totally including flat screen, pyramid screen, steel fram screen, soft/hard hook strap screen, composite screen, PU screen, etc.

Furthermore, shaker screens also divided into single layer, two layers and three layers screens. Then, subject to shale shaker screen mesh size including common mesh screen, fine screen, super find screens. We have all types screen for sale. The flat or PMD, the hook striped or wedge clamped.

                                   

 

The following is Screens API size

The API RP13C is rather essential international standard. These standard issues including the API screen size, D100 cut point range, conductance, non blanked area. Generally, from 20-400 or API20-API425 for shale shaker.

If we request API140 screens its opening size is about 104microns while the cut point range is 98~116.5microns, while the conductance is variable according to different design and different manufacturer.

Commonly it will be 0.99~2.24, etc. None blanked open area determined by labeling and measuring every opening on two production screens.

So, when we select or purchase shaker screens, the API size is universal and standard one. You can tell us the API number or the mesh size, either the cut point of separated particles.

DC Machinery short for TangShan DaChuan Machinery Co.,Ltd. China’s leading manufacturer in regard to shale shaker screen as well replacement screen for all types of shale shakers in the oilfield drilling industry, produces high quality shaker screens, including above listed brand and model.
