The dual-motor Mongoose linear motion shaker is especially effective while drilling top-hole sections where heavy, high-volume solids are usually encountered. In these intervals, shakers need to generate high G-forces to effectively move dense solids across the screens.Following the requirements of drilling, DC Solid control absord abroad advanced technology of Mongoose shakers and combined ourselves design to develop a new type shaker

shaker.

 

DC Solid control DCS585-4 shale shaker is same like Mongoose shaker, and all have 4 pannel screens, and the screen size is same. DCS585-4 Shaker with the large treating capacity(130m3/h, 572GPM). And screens are all steel frame which are convenient to install and change. But only one difference between Mongoose shaker and DCS575-4, it is the movement locus, as we all known, Mongoose shaker is the dual motion( linear motion+ balanced motion), and DCS584-4 shale shaker is linear motion.

If you have interest with dual motion of DCS585-4 shaker, please tell me, that we can design and manufacture the dual motion DCS585-4 shale shaker that will be our new design and progress.

The screens used on the VSM 300 Shale Shaker can be easily changed out to suit operational conditions.

The following screen types are used:

Top Deck Screens (Scalping Screen)

The top deck of the VSM 300 screens utilises multi panel pretensioned screens which are used to scalp off large volumes of solids thus protecting the finer mesh of the lower deck screens. The top deck screens are retained in position by pneumo seal clamping systems which enable rapid screen change out.

VSM300 Screen

Lower Deck Screens (Primary)

The lower deck screen configuration of the VSM 300 comprise four (4) multi panel pretensioned screens. All the screens are mounted on a constant 7° ramp. This screen configuration ensures consistent conveyance of solids thus minimising solids build-up. This results in a higher throughput capacity. The lower screens are retained in position by pneumo seal clamping systems which enable rapid screen change out.

VSM300. Screens

Secondary Screens (Drying Screens)

Optional screen carriers are provided to enable secondary screens to be fitted to the front of the lower deck screens. This facility should be used to reduce fluid levels on cuttings when drilling with low toxicity or synthetic oil based muds. The secondary screens and carriers are fitted into ‘C’ channels and held in place by pneumo seal clamping systems which enable rapid screen change out.

Shale shakers are a type of industrial equipment used to remove rock particles from drilling fluid. This drilling fluid, or mud, plays a critical role in the drilling process. To understand how the shale shaker works, it’s helpful to understand how it relates to other parts of the drilling process.

shale shakers

Once drilling begins, this fluid travels down through drilling cables and enters the bore via holes in the drill bit mechanism. From here it washes back up the sides of the bore, carrying rock particles and other debris back to the surface. Once the mud reaches the surface, it heads back to the storage pit for reuse.

In drilling projects with a mud cleaning system in place, this mud flows directly out of the bore and into the shale shaker. The shale shakers consist of a vibrating tray lined with a wire mesh screen.

The choice of shale shaker screen is critical to successful removal of solid materials. The size of the holes on the screen should be matched to the size of the rock being extracted from each bore hole. It is also important to choose corrosion-resistant screen materials like galvanized steel to hold up against the extreme conditions on a drilling site. Many projects include multiple shale shakers so that the drilling mud must pass through several layers of cleaning and refinement.

There are many famous brand shaker screen in drilling field. Now I introduce a famous brand is Brandt shaker screen.

Frame shale shaker screen

Brandt frame shale shaker screen is a kind of common petroleum shaker screen, it is mainly made of two or three layers of steel frame tight coupling on the frame. The frame stainless steel screen cloth shelf is made of high strength rectangular steel tube or steel flat weld, and has many strengthen support bars.

The screen cloth can combine with frame according to metal scaleboard, or directly bond to the frame. Each screen should attach the special rubber stopper to repair the screen. Our company can accord to customers’ requirements to manufacture all kind sizes of screen.

Plate- type screen

Brandt plate- type screen is also a kind of common petroleum screen, can widely used in different industries drilling fields. The product made of 2 or 3 levels stainless steel screen cloth bonding on the opened pore metal scaleboard.

Meanwhile, screen has the special rubber stopper to repair screen damaged, it can effectively save times, decrease production cost. Our manufacturer has the rich production experience and mature technology, we can accord to different customers’ requirements to manufacture many sizes hookstrio plate screen.

 

Shale shaker screen is one of the main accessories of shale shake, if it damages will serious influence the use of shale shaker, so if the screen is damaged what shall we do?

The solution method for damaged screen 

A When the screen quality is below the standard, usually screen has the upper screen layer and down part stress layer. The two layers should be closely jointed. If the tension process of shaker screen is bad, when screen bottom stress layer is tightened, the screening layer is not tensioning, the thrown force is decreased when work and can’t discharge drilling cuttings.

B If the screen tension strength is not enough lead to screen vibrate, usually the screen edge or bordure layering place is damaged.

C The veer of vibration motor is error, the field operation worker according the use experience of single shaft shale shaker or linear motion shale shaker, think that the drilling cutting is jee is ok, but the method is don’t apply to balance ellipse shale shaker. if the motor false rotate to medial, although the throw angle is 45°but the drilling cuttings have the force of rolling back, the speed of drilling cuttings forward migration is slowly and stay at the screen time is long, even lead to drilling cuttings can’t be discharged.

The solution method:

a when screen box operates, pressing the stop button of electric control box, the shale shaker will stop, observing the ellipse locus produced by the dot moves on side plate of shale shaker, tolling to sand moth is the right direction.

b unsnatch vibration protecting cover and checking the eccentric block whether rolling to outside.

c exchange any two lines of electric control box power source, scatting some sand on screen, the desilting sand speed is more quick is the right direction.

D The vibration amplitude is too small of clay is cumulate, in polymer drilling condition is difficult to screen, it can effective overcomes the viscosity force of drilling cuttings lead to the drilling cutting cumulate on screen and damage the screen.

Solution method

a increasing vibration amplitude.

b using spray water wash screen or drilling cuttings to decrease drilling cuttings’ viscosity, but the method only apply to permit adding water occasion

c adjusting the shale shaker screen angle of desilting mouth end and is conducive to rock debris is discharged by gravity, but maybe lead to running mud.

d replacing screen mesh or adjusting the single screen flow, to ensure the stagnation point of drilling fluid close to screen export to make drilling cuttings is discharged by the function of drilling fluid lubricate. 

As we know the easiest damaged part of shale shaker is screen. So drilling works have a problem that how to correctly replace shaker screen. The experiment show that according reasonable replacement steps can make screen is more efficiency and with longer service life.

Tearing down the old screen cloth

Stop to transport mud to inlet groove, desander and desilter.

Clean up the residue on screen cloth.

Cut off the electric source of vibration motor and locked.

Using combination tool, clockwise direction turn the tensing screw.

a turning the gradient lock 2 turn 90°according anti-clockwise direction.

b turning the gradient lock 1 turn 180°according anti-clockwise direction.

c turning the gradient lock 1 turn 90°according anti-clockwise direction.

Using one side of combination tool hooks upright row and dismantle screen cloth.

The installation of new screen cloth

The external rim of shale shaker screen cloth put on the fixation hook of inner screen reel.

The screen cloth is shifted down, using fixed hook grapple the external rim of screen cloth.

Continue to lower screen cloth to contact the flank supporting of screen bed and fixed hook completely grapple the crook of screen cloth.

One set of tensing assembly tensioning screw spin clockwise 90°make screen cloth tensioning and keep in tensioning location. Now don’t put a nut on the full 180°.

The second tensioning screw clockwise rotation 180°.

Returning to the first tensioning screw clockwise rotation 90°get to completely clamp location.

Ensure screen cloth have already completely contact flank supporting, cross supporting. If the screen cloth is flabby or has corrugate ruga, removing tension and retightening tension screw to make screen cloth completely contact screen bed.

Shaker screens are expensive expendable. No matter for which brand shale shakers will request high quality shaker screen for good performance or efficiency during the operation. Especially to famous brand shale shakers. So we must master how to replace screen.

Shaker screen is one of the important mountings of shale shaker, the installation of shaker screen is the key of screen using quality. If the quality of screen is very good but with the fault installation, it is also cask of danaides. If the screen is damaged will serious influence the use of shale shaker.

Shaker screen existents some problems

Because the tensing device of shale shaker is not complete stretched and easy to make screen is damaged with linear.

 The length of shaker screen should be properly adjust. Lengthy shaker screen will make the tensing device can’t complete fasten and make equipment produce loose and the screen is damaged at last.

 If the interval is too small which is between screen and screen box will abrade equipment components when installation.

 The screen is not tension will influence screen efficiency.

 After the net rack is installed in screen box, if the screen is not stretched into the homologous discharge hole will appear mixing phenomenon.

 The seal of screen is not tension will appear mixed level phenomenon.

Experts give some solve skills 

The screen of linear motion shale shaker should choose the wire diameter is relatively thick stainless steel screen, the service life is long.

 Because the tension of shaker screen is directly influence screening efficiency, so the screen is must tension and installed.

When shear screen, the length should be longer 50-70mm than steel frame, the width should be consistent with screen.

Firstly we come loose the beam ring screw and discharge the upper ledge, taking off the damaged fine screen and replace new fine screen.

The fine screen is tiled in shale shaker mother screen and the upper ledge is placed the reposit。

All round fine screen is out of the architrave should be eliminate and persisting 2cm.

Selvage should be reputed and loose the combination pliers, the screw of selvage should be hooked and locked.

After installation, putting some materials test the screening machine, according the requirements to adjust the uniformity and evenness of screen and check the seal of screen.

At last we should periodic check screen in using process, if we find problems we should solve it at times.
