Shale Shaker and Hydrocyclones for Solids Control or Mineral Processing

Shale shakers and hydrocyclones are both components of solids control equipment used in many industries, such as oil and gas drilling, coal bed methane (CBM), horizontal directional drilling (HDD), diamond drilling, water drilling. They used to separate drilling cuttings for first phase cleaning in a whole solids control system. They are also both used for mineral processing for classification or dewatering based on the materials’ particle sizes.

  1. Shale shaker or vibrating screens:

In a solids control system, once processed by the shale shakers, the drilling fluid is deposited into the mud tanks where other solid control equipment begins to remove the finer solids from it. The solids removed by the shale shaker are discharged out of the discharge port into a separate holding tank where they await further treatment or disposal.

A vibrating screen is a key piece of equipment in mineral processing. It’s used to separate feeds containing solid and crushed ores down to less than 200 μm in size. The vibrating screens take a tough job and also responsible for the heaviest burden for separation.

  1. Hydrocyclones

Hydrocyclones are a type of cyclonic separators that separate product phases mainly on the basis of differences in gravity. They are used with aqueous solutions as the primary feed fluid1. Unlike dry or dust cyclones, which separate solids from gases, hydrocyclones separate solids or different phase fluids from the bulk fluid.The hydrocyclone separator uses pressure created by a centrifugal pump or hydrostatic head to generate centrifugal force and flow patterns within the hydrocyclone. It does not have any moving parts.

Hydrocyclones have different sizes, in a solids control system, the most popular 2 sizes are 10 inch and 4 inch diameters. For mineral processing, larger sized hydrocyclones are adopted.

  1. In practice, the shale shakers are more efficient than hydrocyclones, and also consumes less power. That’s why more and more end users would like to replace the hydrocyclones by shale shakers, but there is a challenge that the cut point of shakers are not easy to become so small. Now GN high frequency fine sizer series vibrating screens can solve this problem by using flexible polyurethane screen meshes with fine apertures.

GN Desander and Desilter and Shaker to Indonesia Project

Indonesia is a country in South East China with a rich reservation of crude oil, and the oil drilling industry is quite active there. At first, years ago, all drilling companies are only buying from US or European companies for the equipment used in drilling procedures. But now, lots of them are turning to Chinese manufacturers like GN Solids Control, one of the leading international brands.

GN Solids Control has been manufacturing the solids control equipment for more than 16 years, and has exported to more than 70 countries in the world from its headquarter in China, and the branch companies in USA, Australia and Russia.

In a recent project, a client from Indonesia ordered a batch of solids control system from GN for 4 drilling rigs. They are following:

1.Shale shaker. Shale shakers are the first step solids control to remove particles above 100 microns from drilling fluids.

2.Desander cones, Desander are 10 inch cyclones with underflow shaker to remove particles larger than 40 microns. For this Indonesia project, GN offered a small sized underflow shaker. The underflow shakers for cyclones are used for the weighted mud.

3.Desilter cones, they are cyclones of 4 inch diameter for removing the 20+ micron particles from the drilling mud. They share the same working principle like the deander cones. Those desilter cones are also equipped with underflow screens.

4.Mud guns and mud agitators. They are auxiliary equipment for the whole solids control system but quite necessary. They prevent the mud from settling down to the bottom of tank.

Besides the single equipment, GN also has the ability to design or customize the whole system for clients. Welcome to contact GN for more information. And also welcome to visit GN Companies in China, USA, and Australia.
