GN Solids America LLC’s linear motion 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 commission the shale shaker, keep put the shaker on a horizontal base. The base needs to be firmed.

The shock-resist rubber material should be installed between the working table and equipment.
Remove the shipping brace like bolts and lugs because the base and screen box are connected by springs, so when ship, the above part of the equipment is secured by the shipping braces.
Do not turns on the equipment before remove the shipping braces.
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 is washed by clean water.

The installation of shale shaker screens

Clean the adhesive side well and put on the shaker screens.
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 screens.
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.

Solid control equipment used in mud gas separation


GN Solids Control is a world-famous company specializing in manufacturing drilling mud solid control and waste management and recycling. Its product range covers shale shaker, desander, desilter, vacuum degasser, decanter centrifuge, cutting dryer, centrifugal pump, screw pump and so on. Its products are mainly used in oil and gas drilling, civil works(like piling, TBM, HDD), and mining industry.


In the oil and gas drilling application, there is one important equipment in the solid control system, that is vacuum degasser. It is usually used after the shale shaker and before the mud cleaner. The main application of the degasser is to eliminate the gas immersed in the drilling mud, which will help restoring the mud weight, stabilizing the slurry viscosity, reducing the drilling cost, and preventing the well blow out accident. The vacuum degasser is mainly composed of vacuum tank installed on a skid base, vacuum pump, gas water separator, control panel, explosive proof motor. Its working principle is that: under the effect of the suction power from vacuum pump, negative pressure zone will be generated in the vacuum tank, and the drilling mud will enter the hollow shaft of the rotor through the suction tube under the effect of the atmospheric pressure. Then the mud will hit the windows of the hollow shaft and be sprayed to the wall of vacuum tank. Under the collision effect of the separation baffle, the mud will be separated into thin layers, and bubbles immersed in the mud will be broken up and comes out. The gas will be discharged by the vacuum pump and gas water separator to the safe zone, the mud will be discharged outside of the tank by impeller. In the whole process, the rotor will keep running at high speed under the power of main motor.


Now GN has two kinds of vacuum degasser: GNZCQ270A and GNZCQ360A, the processing capacity for these two equipment is 270m3/h and 360m3/h. Welcome to visit
