Category Archives: Shale Shaker

Shale shaker is widely used in many fields. The common shale shaker is linear motion shale shake and balanced ellipse shale shaker. But the only two types shale shaker have already can’t meet users’ requirements. Different field should use different types of shale shaker, but if in the same field need use linear motion or balanced ellipse motion shale shaker at the same time. One set shale shaker can’t meet the requirements.

So according to the needs, Mi-swaco produced a shale shaker which is linear motion and ellipse motion combination. We call it Mongoose PRO shale shake or dual motion shale shaker.

SONY DSC

The mongoose shale shaker has three vibration motors to control the vibrating model. When we need linear motion we can start two motors, if we need ellipse motion we can start three motors. It has a control cabinet can switch the linear motion or ellipse motion.

Operators can change the type of motion required to either handle high volume or produce dryer cuttings, as drilling conditions dictate. With the MONGOOSE PRO shale shaker, nonproductive time lost to changing out shakers to meet drilling conditions is no longer an issue.

The MONGOOSE PRO shale shaker, the latest upgrade to the MONGOOSE line of shale shakers, outperformed an earlier generation shaker in both flow capacity and cuttings discard rates while maintaining the same cuttings dryness.

Classification

The common ellipse shale shaker: the screen box makes elliptic motion when works and do pitching motion coil centroid.

Circular shale shaker: the screen box makes round locus motion when works.

Linear motion shale shaker: the screen box makes liner motion when works

The technological level of shale shaker is mainly reflect on the processing capacity, the stability of working, the length of service life and the flexibility of operation. The processing capacity of shale shaker is related with the structure, movement locus, vibration frequency, vibration strength, screen area and thickness.

Usually the modern shale shakers are high speed, linear, fine mesh, multilayer shale shaker. It plays the important roles in solid phase control system.

Circular shale shaker

Single shaft inertia shale shaker adopts eccentric shaft or eccentric block as the exciter. The movement locus is circular or quasi-circular. It has the advantages of the structure is simple, cost lower, migration is convenient, easy to maintain compared with double shaft inertia shale shaker.

Linear motion shale shaker

The two eccentric blocks with equal quality do synchronization contrarotation produce the

equal centrifugal force. In each instant position, centrifugal force plus the geometrical sum of these force which along with vibration direction is cancelled out with the geometrical sum of these force of vertical direction. So the exciter only form the exciter force in

vibration direction t make screen box do linear motion vibration. Usually the throw angle of drilling fluid linear shale shaker is 45°~60°.

Ellipse motion shale shaker

Ellipse shale shaker integrated the advantages of linear motion and circular shale shaker. The long shaft of ellipse shale shaker is the component of strengthen transportation material, the short shaft can decrease parts materials block the holes. In general condition, the total throughput of ellipse shale shaker is bigger about 26% than linear motion shale shaker ad circular shale shaker.

In order to prevent the innerstress is appeared from welding don’t allow weld screen box and any auxiliary parts.

We should adopt these steps when weld shale shaker

Drilling 6mm hole in one end of flaw in order to prevent flaw extend.

Using round shovel spade groove along two sides of flaw.

Firstly preheat about 60℃ using 3mm diameter welding electrode to prevent any slag inclusions and bite meat condition.

Rubdown the protuberant electrode and weld the stiffening plate.

If id needs weld in screen surface bracket beam, all welding line should be parallel with beam.

When use alternating current weld the screen box should connect the ground to prevent current conveyance the bearing. Otherwise it is easy to led bearing damage.

The cutting surface will produce stress when flame cut, so the any addition holes all advised drill.

Installation requirements of mud shale shaker

When knit drilling fluid shaker screen and screen bracket is matched special vibration attenuation rubber strip. In order to make screen can reach the longest service life, the rubber strip should placed in among of screen and bracket.

We should ensure the equal interval between two sides of shale shaker screen box and screen hook when replace knit screen, we should fix the centre and compact steel flat at first, then tension the plate to keep the stress of screen surface is uniformity. It is one of the premature failure reason If the connecting is not good, the stress is not enough or uneven.

The factors are decided the performance of shale shaker: vibration type, amplitude and frequency, the inclination of screen, the number of screen and screen area.

Factor one: vibration type

The vibration type of shale shaker has three types, round type, ellipse and linear motion, every motion type is the oscillator is in the different locations in the system centre to produce. The oscillator in the system centre gravity produce circle type motion; oscillator is in the up of centre gravity produce ellipse type motion. The screen surface must have inclination to ellipse motion and transport drilling cuttings. But the screen surface will decrease the screen content. The oscillator is in the front above of centre gravity will produce linear motion and eliminate solid phase. Linear motion has the fixed drilling cuttings transportation speed, screen surface can be plane and a little bias.

Factor two: Amplitude and frequency

The screen content of shale shaker is decided by three parameters; amplitude or stroke, vibration type and oscillator rotary speed. The oscillator rotary speed decided the size of shale shaker vibration frequency, rotary speed is more high, vibration frequency is more high, eliminate solid phase effect is more good. The vibration frequency of domestic high frequency shale shaker is 2000 times/min. The size of drilling fluid shale shaker is decided by the quality and eccentricity. The amplitude is the distance of shake screen vertical motion.

Factor three: the inclination and mesh of screen cloth

Screen cloth drive all drilling fluid movement according vibration to separate solid phase. Usually the ellipse motion shale shaker is installed according different inclination. The purpose is reasonable discharge drilling cuttings, the screen surface can be a slope, it also can be divided into several slopes. Multistage shale shaker have multideck screen cloth, drilling fluid must through the first screen cloth then enter into second screen cloth in the 2-3 screen cloth shale shaker.

Factor four: screen

Drilling fluids shale shaker is the main method of solid phase separation. If shale shaker use is unreasonable or the size of screen is unreasonable, solid phase separation efficiency will be decreased. If the installation of screen is unreasonable and the support is not enough, the screen will be quickly frayed or tear.

A The screen cloth can be square, rectangle and multilayer design.

B Weaving type is the important factor of screen design. It mainly has plane square woven, rectangular holes woven, plain grid woven and twill. The grid and rectangular is widely used.

C The size of screen has two different ways, screen hole diameter and mesh. The mesh is referring begin from centre line, the number of holes of every inches.
