Shale Shaker Facts

Shale shaker facts

Model choice of  fluid shale shaker

The shale shaker is choose by the following facts:
The handling capacity (GPM)
The type of fluid, the ratio of the mass density, the speed of flow and temperature
salt and/or acid of materials (Confirm to use 304# stainless steel or 316L stainless steel)
Size of the solids material and screening accuracy needed
The sums of meshes (API)
The placed-area size to place the shale shaker in oil field

The  set-up of shale shaker

When first set-up the shale shaker, keep put the shaker on a horizontal base. The base need to be firmed.
Possible there is no base, the shock-resist rubber material should be installed between the working table and equipment.
Remove the shipping brace like bolt and lug, because the base and screen box are connected by springs, so when ship, the above part of the equipment is secured by the shipping brace.
Do not turn on the solids control equipment before remove the shipping brace.
The cables connected the vibration motors on the shale shaker always damaged during severe vibration. Protected-cover for the cable is provide and need to install with cable when connect control panel and the motors
When stop using the shale shaker, the shale shaker screen should always be washed by clean water.

The installation of shale shaker screen

Clean the adhesive side well and put on the shaker screen.
Install the wedge blocks at the two sides at the same time.
Do the test-run after the installation of shaker screen to ensure installation is done properly. If there is any unusual noise of poor contact, stop immediately and recheck the installation of shaker screen.
The tilt-angle adjustment of screen box

When the volume of fluid running is too large, the mesh screen should be changed. When fluid running is small, the  angle should be adjusted by tilting.
The  angle of the screen should be tilted according to the actual demand. The adjustment range is -1 to +5 degree. When adjust the tilt-angles, take off the pin first, loosen rings screws, then run the manual and/or electric hydraulic pump.
When the shale shaker properly works , the fluid should flows 3/4 of the whole screen, if the fluid can not flows as much as required, in order to increase the effect of cleaning, the shaker screen should be changed.


GN VFD Decanter Centrifuge for Dewatering Unit

GNLW363BG-VFD is an ideal and popular decanter centrifuge with a speed range from zero RPM to 3900RPM, which character enables GNLW363BG-VFD to be suitable for more than one applications in drilling field such like a medium speed centrifuge in solids control system or a high speed decanter centrifuge in a waste management system, and also a high speed decanter centrifuge in a dewatering system.

What is dewatering system?

In most solids control systems, drilling mud shale shaker, desander, desilter and waste management systems which may contain vertical cuttings dryer and a high speed decanter centrifuge could separate out and dispose solids particles larger than 5 microns. In most cases, the drilling mud could return to the drilling system for re-use. But after the drilling mud being circulating for a long while, the particles may be smaller and smaller, and difficult for the centrifuge to separate. Then, dewatering unit comes into necessary.

In a word, dewatering unit is used to chemically flocculate the too fine or ultra-fine solids particles into larger ones, at least larger than 5microns for the decanter centrifuge to separate them out. Before dewatering, the solids control system is about physical separation while dewatering unit combines the physical separation and chemical separation.

GN Solids Control is professional to provide all related solids control and waste management systems above mentioned, and also capable of providing such GN 20ft container dewatering unit.

What’s the benefit of GNLW363 Dewatering Centrifuge?

GNLW363BG-VFD is VFD controlled high speed decanter centrifuge( with a perfect separation capability.

  1. GNLW363BG-VFD has a international popular positive pressurized control panel.
  2. GNLW363BG-VFD is equipped with world famous top bearing SKF.
  3. GNLW363BG-VFD uses SS2205 stainless steel for bowl material for more anti-corrosive and anti-wearing.
  4. GNLW363BG-VFD use tungsten carbide material as impeller protection and solids discharge port, easy for exchanging and long service life.
