GN Economic Mud Recycling Unit

Most of the drilling project will need a drilling mud recycling unit to reduce the drilling cost and promote the drilling process. In normal oil and gas drilling project, always the usage of the drilling fluids is very large that need several mud tanks to store the drilling mud. Different from this type drilling, there are several other drilling projects that no need a large drilling mud volume. The footprint and cost are the key factors the contractor will consider.

As a leading drilling fluids recycling equipment manufacturer and supplier, GN solids control also has a good reputation in the HDD and piling market. This type drilling project need compact structure and cost economic mud recycling unit.


GN has a self-contained drilling mud system  designed especially for HDD project. As per the flow capacity, the mud system design is classified into 200GPM, 350GPM, 500GPM, 800GPM, 1000GPM and 1500GPM. Most of the design only has one skid with all primary solids control equipment installed on one tank. According to the mud storage capacity requirement, additional storage tanks may be needed. Some users request decanter centrifuge for fine solids separation. Always this type mud system has all mud recycling equipment, transferring pump and mud mixing equipment. Comparing with oil drilling mud system, the HDD mud system has smaller footprint and the cost is less.

For some drilling project like the piling process or TBM drilling, the separation of drilling mud is not so strict. The contractors only need a de-sanding unit to remove the large size solids in the drilling mud. GN’s this type de-sanding unit includes shaker unit and de-sander cyclone installed on over the shaker. This separation unit can process 2 stages solids control. Under the shaker, a catching tank can used to temporally store the active drilling mud; it also has a transferring pump to pump the mud to drilling rig or to storage tank.  The contractor can use other type storage tank to connect with this de-sanding unit and get a skid mounted jet mud mixing unit to compose a drilling mud recycling system that has larger mud storage capacity and mud mixing function.

If you need a drilling mud separation system for small drilling project, please don’t hesitate to contact with GN solids control for a quote and design.

Decanter Centrifuge buying guide

Decanter Centrifuge is the machine that use high rotating speed in gravity force to separate solids from water.  The decanter centrifugeis also able to separate two liquids that differ in density as well if higher rotating speed is reached by more powerful motor which can produce higher RPM.  Depending the RPM of the decanter centrifuge motor, it can produce the rotation force in 1000 times and beyond on normal gravitational force.  The separation time need it from minutes to hours.  The bowl tube that equip with internal conveyor rotate in extreme high speed that moves in same direction but at different velocity to achieve solids separation from liquid.  Many industry such as oil and gas field, food processing field, chemical plant and environment treatment company are using decanter centrifuge.  The only difference between these industry choosing decanter centrifuge is material in the rotating bowl.  When choosing a decanter centrifuge, ensure wetted parts that makes contact with treat subject are made with high quality of steel.  Decanter centrifuge use to treat chemical and subject that will cause corrosion like drilling fluid in oil and gas industry, the metal need to choose forged titanium or haste alloy.  While food process industry, it is need to be aware of polished stainless steel because of buildup of bacteria.


Other factor need to consider while choosing decanter centrifuge is treating capacity.  This is the volume of treating subject the centrifuge can process per minute.  It is refer GPM (gallon per minute) since the purpose of decanter centrifuge is treating liquid to separate solids from it.  Decanter centrifuge treating range can be from 5 to 1000 GMP.  Another capacity to consider is the motor that drive the bowl, which can be range from 25 hp to multiple hundreds hp.  If buyer is considering used decanter centrifuge, it need to know the prior industry and usage.  This consideration is to avoid contamination, corrosive and hazardous material.  Used vendors often offer immediate installation and aggressive pricing which is advantage for time and price sensitive projects.

Shaker Screen Mesh Size Design and style

Plain square and rectangular weaves are usually referred to by the amount of wires (or openings) in every single path per linear inch. This really is known as the mesh count. The mesh count is determined by starting at the centre of one wire and counting the number of openings along the Shaker Screen grid towards the next wire centre, one linear inch away. One example is, an 8-mesh screen has eight openings in two directions at right angles to each other. When counting mesh, a magnifying glass scale designed particularly for this objective is helpful.

Use of a single quantity for describing screens implies a square mesh. By way of example ?°20 mesh± usually describes a screen having 20 openings per inch in either direction along the screen grid. Oblong mesh screens are frequently labelled with two numbers. A°60 x 20 mesh?, for instance is normally understood to possess 60 openings in a single path and 20 openings per inch within the perpendicular direction. Referring to a ?°60 x 20 mesh? screen as an ?°oblong 80 mesh is confusing and inaccurate.

The actual separation that a screen is capable of is largely determined by the size of the openings in the screen. The opening size is definitely the distance among wires measured along the screen grid and is expressed in either fractions of an inch or in microns, though it is most usually stated in microns. One particular inch equals 25,400 microns. Preserve in mind, specifying the mesh count does not specify the opening size. That is because each the amount of wires per inch and the size of the wires determines the opening size.
