Desander Equipment

Essential solids removal system for protecting drilling equipment and maintaining fluid properties

What is a desander?

A desander is a critical component in solids control systems that removes abrasive sand-sized particles (typically 45-74 microns) from drilling fluids. These solids can cause excessive wear on pumps and other drilling equipment, reduce drilling efficiency, and compromise drilling fluid properties.

JKZ desander utilize hydrocyclone technology to efficiently separate sand and abrasive solids from drilling fluids, protecting downstream equipment while maintaining optimal mud properties. Our units are available in various capacities to match different rig requirements and drilling conditions.

Desander Components

Key parts that make up a high-performance desander

Hydrocyclone

Hydrocyclones

The core separation components that use centrifugal force to separate solids from drilling fluids. JKZ hydrocyclones feature optimized cone angles and inlet designs for maximum separation efficiency. Constructed from wear-resistant polyurethane or ceramic liners for extended service life.

Our hydrocyclones are precision-engineered to maintain consistent cut points and handle varying flow rates without performance degradation.

Manifold Assembly

Manifold Assembly

Distributes drilling fluid evenly to all hydrocyclones for balanced operation. JKZ manifolds feature optimized flow channels that minimize turbulence and pressure loss.

Constructed from abrasion-resistant steel with replaceable wear plates at high-erosion points. Includes isolation valves for individual hydrocyclone maintenance without shutting down the entire unit.

Shaker Screen

Shaker Screen

Vibrating screen that further de-wets separated solids from the hydrocyclone underflow. JKZ screens feature high-quality mesh with various opening sizes to match different drilling conditions.

Our linear motion shaker systems provide efficient solids conveyance with minimal fluid loss, featuring adjustable vibration intensity for optimal performance with different solids types.

Control Panel

Control System

Advanced control panel with motor controls, vibration adjustments, and safety features. JKZ control systems include motor overload protection, variable frequency drives for shaker adjustment, and visual indicators for operational status.

Optional remote monitoring and PLC controls available for integration with rig control systems. All electrical components meet international safety standards for hazardous environments.

Desander Structure

Engineering design for optimal solids removal efficiency

Desander Structure Diagram

JKZ desanders feature a carefully engineered structure designed to maximize solids removal efficiency while ensuring reliable operation. The key structural elements include:

Inlet Section: Designed to smoothly introduce drilling fluid into the manifold without creating turbulence that could degrade separation efficiency.

Hydrocyclone Bank: Array of precision hydrocyclones mounted at optimal angles to maximize solids separation while minimizing pressure drop.

Shaker Deck: Vibrating screen section that receives underflow from hydrocyclones, further separating liquids from solids with minimal fluid loss.

Solids Discharge: Efficient discharge system that routes separated solids away from the unit, with optional conveyors for remote disposal.

Support Structure: Heavy-duty frame with vibration isolation and corrosion protection for long service life in harsh drilling environments.

Desander Working Principle

How hydrocyclone desanders remove abrasive solids from drilling fluids

Hydrocyclone Separation Technology

JKZ desanders utilize the principle of centrifugal force to separate solids from drilling fluids. The combination of hydrocyclone separation and vibrating screen technology ensures thorough solids removal with minimal fluid loss.

1

Fluid Inlet

Drilling fluid enters the hydrocyclone tangentially under pressure through the inlet nozzle.

2

Centrifugal Force

The fluid spins rapidly inside the hydrocyclone, creating strong centrifugal forces that push heavier solids toward the wall.

3

Solids Separation

Heavier solids move downward along the cone wall and exit through the underflow opening (apex).

4

Clean Fluid Return

Cleaned drilling fluid moves upward in a reverse spiral and exits through the vortex finder (overflow).

5

Solids Dewatering

Solids from hydrocyclone underflow are further dewatered on the shaker screen before discharge.
