Drilling mud shale shaker is a kind of mud processing equipment with a wide range of uses. In the field of oil drilling, it is often used as the first-level solids control equipment to process drilling mud. Information about the working principle, purpose, structure, installation, operation, and maintenance of the shale shaker will be sorted out and shared with you.

The working principle of the drilling mud shale shaker:
The excitation force generated by the motor drives the shaker screen to move in a straight line, a circle, an ellipse or a translational ellipse. The screen will play the role of filtering and screening, sieving out solids such as large particles of drill cuttings, and the treated clean mud with fine particles will fall to the shale shaker bin to wait for the next level of processing. The separated large solid particles (usually above 74 microns) are transported to the outside of the shaker screen under the excitation force and discharged out of the tank.
The scope of application of drilling mud shale shaker:
On land, offshore oil and gas drilling / coalbed methane excavation / trenchless excavation / piling engineering / waste sewage, mud treatment and other projects, the primary or secondary or tertiary solids control treatment of mud and liquid to be treated. In short, it is suitable for the primary treatment of mud and solid-liquid mixtures in various environments.
Factors affecting the performance of drilling mud shale shaker:
Drilling depth, drilling fluid performance, land environment, comprehensive drilling environment/conditions, selection of screens, objects to be processed, etc.
The structural components of the drilling mud shale shaker:
Mainly include base, frame, shaker screen, mud tank, excitation beam, excitation motor, control cabinet, shaker body angle adjustment device, shaker screen, screen fixing device, etc.

Installation instructions for drilling mud shale shaker:
Usually the drilling fluid shale shaker is installed on the first mud tank. There will be blocks at the location to help users confirm the location and distance. The top of the tank where the shale shaker is located will also have an opening the size of the shaker screen to receive the cleaned mud. The mud tank should be placed on a flat and clean ground to minimize the impact of the external environment on the performance of the shale shaker. In the process of transportation or transfer, it is not advisable to install the screen on the shaker body to avoid collisions and other damage to the screen. The transportation locking device must always be in a tightly closed state. After installation, the transportation locking device should be removed before use to ensure the normal operation of the shale shaker. During the installation process, read the installation manual and follow the corresponding constraints to complete the installation.
Safe operation of the drilling mud shale shaker:
It must be ensured that the transport locking device is removed before use. The equipment cannot be repaired, moved, or even disassembled during the use of the shale shaker. Operate and maintain the equipment in accordance with the safe operation instructions and warning signs given on the equipment.
Maintenance of drilling mud shale shaker:
- The motor should be maintained regularly and reasonably according to the safety warnings of the motor, such as adding lubricating oil, etc.;
- In the process of using, carefully observe and inspect the condition of the shaker screen. The damaged screen and the completely damaged screen should be repaired or replaced in time;
- After each stop of use, the shale shaker and the screen should be cleaned when necessary to ensure the screen have a longer life;
- Inspect and maintain the overall condition of the shale shaker in a regular and planned manner, so as to achieve the best performance of the shale shaker.
- Precautions for using the drilling fluid shale shaker: during the use of the shale shaker, slurry running or screen blocking may occur. At this time, we need to adjust the angle of the shaker body, but it should not be excessively raised or lowered.
- Timely observe and monitor to ensure that the selected screen is suitable for a certain stage of mud. When the shale shaker does not follow the predetermined mode, it may be a problem with the motor circuit. For example, only a single motor is running or the installation direction is wrong. At this time, disconnect the source and check the motor or circuit to restore it to normal.
