In the modern oil and mining industry, the production process requires the mandatory use of a special type of equipment-vibrating screen, whether it is a single version or a composite form designed for multi-stage processing of specific raw materials. In the oil and gas industry, shale shaker are used to clean drilling washing fluid (solution) from drilling rock particles (drilling mud).

 

 

Applicability of vibrating screen

Vibrating screens are usually used in the initial stage of drilling mud cleaning. By processing the solution on a vibrating screen, it is roughly cleaned from the largest rock particles ranging in size from 70-80 microns. Therefore, drilling mud undergoes pretreatment. Without pretreatment, it is impossible to use the subsequent stage of cleaning from the sludge, namely in the sludge separator and hydrocyclone. In fact, no modern drilling rig is complete without compulsory presence of a vibrating screen on its platform, as a high-efficiency and high-performance equipment for restoring the technical performance of expensive washing liquids.

Vibrating screen design
 

In terms of structure, the device of the vibrating screen is quite simple. The main nodes of the vibrating screen include:

Support frame;

Power frame;

Holder;

Screen panel;

Protective cover.

The working principle of shale shaker

The operating principle of the vibrating screen is also quite simple: the drilling mud contaminated by the drilling rock particles is fed into the surface of the screen plate fixed in the fixed frame at a certain inclination angle. Under the action of the oscillating movement, the cleaned material moves along a certain track along the surface of the mesh. During such vibration treatment, the gravitational separation of the small and large fractions of the sludge occurs on the surface of the screen: pollutant particles larger than the mesh size do not pass through it, and large inclusions due to continuous movement under the influence of vibration The clean drilling mud, and the smaller sludge particles contained therein, are naturally filtered through the sieve, and then they are transferred to the cleaning solution from the smaller sludge fraction through a special port
