Drilling Fluid Shale Shaker Manufacturers | Solids Control Equipment

Drilling fluid shale shaker is a key piece of equipment in drilling operations to control drilling fluid properties, maintain wellbore stability and improve drilling efficiency. As the primary purification device in the drilling fluid solids control system, its main function is to remove harmful solid cuttings from drilling fluid and provide favorable conditions for subsequent purification equipment.

Drilling Fluid Shale Shaker

Drilling fluid shale shaker is the first solids control equipment in the drilling mud purification system. It is mainly used to separate harmful solid particles such as cuttings with a particle size ≥ 74μm from drilling fluid, ensuring stable drilling fluid performance and providing qualified drilling fluid for downstream equipment. It can also be used as the underflow shaker for mud cleaners.

Working Principle of Shale Shaker

The shale shaker operates by using a motor to drive vibrators, creating a periodic inertial force. Drilling fluid flows onto the shaker screens. Under the exciting force, the basket, along with the screens, undergoes linear, circular, or elliptical motion. As the drilling fluid passes over the screens, solid particles are retained on the screen surface and discharged, while the liquid phase passes through the screens, achieving solid-liquid separation.

1. Excitation Force Generation：Usually generated by two vibrating motors or vibrators rotating in opposite directions based on the self-synchronization principle.

2. Solid-Liquid Separation：Under vibration force, solid particles are lifted and moved forward on the screens until discharged. Liquid and fine particles smaller than the screen aperture pass through the screens into the mud tank below, completing solid-liquid separation.

Shale Shaker Structure and Classification

1. Main Components：

   Screen box, special Shaker Screens (wave screens / pre-tensioned screens), vibration motors, shock-absorbing springs, base frame and angle adjustment mechanism.

   Screens are mostly fixed with wedge block quick-clamping devices for easy on-site replacement.

2. Main Types

   Linear Motion Shale Shaker：Fast solids discharge, suitable for high-viscosity oil-based mud.；

   Elliptical Motion Shale Shaker：Balances processing capacity and screening accuracy, ideal for complex formations.；

   Double-Deck / Multi-Deck Shaker：Graded filtration, capable of recovering barite.；

   Vacuum Shale Shaker：Suitable for ultra-fine particles and low-viscosity drilling fluid.

Mainstream Shale Shaker Manufacturers

1. Domestic：TR Solids Control, Aipu Solids Control, GN Solids Control, XBSY.

2. International：Derrick, NOV (MI-SWACO), Schlumberger.

   Derrick's multi-layer high-frequency shakers and TR Solids Control's custom models compatible with international brand shaker screens are highly regarded in the high-end market.

TR Solids Control shale shakers adopt vibration motors for excitation and feature adjustable screen box angle. They have high vibration intensity, large screening area and compact structure.  With a full product range and API certification, the products have served more than 60 countries overseas and won high recognition from customers.

TR Solids Control's drilling fluid shale shakers are widely used in the exploration and development of oil, natural gas, coalbed methane, and shale gas resources, as well as in engineering applications such as trenchless horizontal directional drilling, piling projects, shield tunnel mud separation, and river dredging sludge environmental treatment.

Drilling fluid shale shaker is an indispensable part of the drilling solids control system.  Selection should consider processing capacity, separation particle size, application conditions (deep well, shallow well, special process wells), screen life and reliability.  Its technical level directly affects mud purification quality, drilling speed and overall operating cost.
