Desander Equipment

Second-stage solids control equipment for removing medium-sized particles from drilling fluids

What is a Desander?

A desander is a solids control device that uses hydrocyclones to separate abrasive solids (typically 45-100 microns) from drilling fluids. Positioned after shale shakers in the solids control system, desanders protect downstream equipment by removing medium-sized particles that pass through shale shaker screens.

JKZ desanders feature high-efficiency hydrocyclones with wear-resistant liners, optimized feed headers, and robust construction for continuous operation in demanding drilling environments. Our desanders can process flow rates from 500 to 4000 GPM depending on configuration.

Types of Desanders

Different configurations for various drilling applications

Conventional Desander

Standard desander units with 10" or 12" hydrocyclones for general drilling applications. Features simple operation, easy maintenance, and reliable performance in most drilling conditions.

Ideal for land rigs and shallow wells where moderate solids removal is required. Can be mounted on mud tanks or skids for flexible installation.

Desander Components

Key parts that make up a high-performance desander

Hydrocyclones

The core component of any desander, hydrocyclones use centrifugal force to separate solids from drilling fluid. JKZ hydrocyclones feature precision-engineered cones with wear-resistant polyurethane or ceramic liners for extended service life.

Available in 10" and 12" diameters, our hydrocyclones are optimized for different flow rates and particle size ranges. Each unit undergoes rigorous testing to ensure consistent performance.

Feed Header

The feed header distributes drilling fluid evenly to all hydrocyclones, ensuring balanced operation and maximum efficiency. JKZ feed headers are designed with optimized internal baffles to prevent turbulence and maintain consistent pressure.

Constructed from heavy-duty steel with abrasion-resistant liners, our feed headers withstand high flow rates and abrasive slurries common in drilling operations.

Underflow Shaker

Optional but highly recommended, the underflow shaker further processes the solids discharge from hydrocyclones to recover valuable drilling fluid. JKZ offers various shaker configurations to match specific desander models.

Our underflow shakers feature durable screens, adjustable vibration settings, and easy-access designs for quick maintenance and screen replacement.

Mounting Skid

The structural frame that supports all desander components and integrates with the mud tank system. JKZ skids are engineered for stability, with reinforced construction and corrosion-resistant coatings.

Features include adjustable mounting points, integrated walkways for maintenance access, and optional drip pans for fluid containment. Custom skid designs available for specific rig configurations.

Desander Structure

Engineering design for optimal solids separation

JKZ desanders feature a carefully engineered structure designed to maximize solids separation efficiency while minimizing maintenance requirements. The key structural elements include:

Inlet Section: Designed to smoothly transition drilling fluid into the hydrocyclones without creating turbulence that could reduce separation efficiency.

Hydrocyclone Array: Precisely arranged to ensure equal distribution of flow and pressure across all units, with easy-access mounting for quick replacement.

Overflow Manifold: Collects cleaned drilling fluid from all hydrocyclones and returns it to the active system through a large-diameter outlet.

Underflow Collection: Channels separated solids to the discharge point, either directly to waste or to an underflow shaker for further processing.

Support Structure: Heavy-duty frame with vibration isolation to prevent transmission of operational vibrations to the rig structure.

Desander Working Principle

How hydrocyclones separate solids from drilling fluid

Centrifugal Separation Technology

JKZ desanders utilize the principle of centrifugal force to separate solids from drilling fluids. The hydrocyclone creates a vortex that throws heavier solids outward while allowing cleaner fluid to exit through the center.

1

Tangential Inlet

Drilling fluid enters the hydrocyclone tangentially, creating a rapid spinning motion inside the cone.

2

Vortex Formation

The spinning motion creates a strong centrifugal force that pushes heavier solids outward toward the cone wall.

3

Solids Separation

Solids spiral downward along the cone wall and exit through the underflow (apex) opening.

4

Fluid Recovery

Cleaner fluid moves upward through the center vortex and exits through the overflow (vortex finder) at the top.
