Understanding how shale shaker equipment fits into the broader solids control family helps operators appreciate its foundational role and optimize the entire system. Aipu Solids Control designs its shakers as the primary component in an integrated solids control train.
The Four-Stage Solids Control Hierarchy
Complete solids control typically follows a four-stage hierarchy. Stage one is the shale shaker, removing the largest particles—typically above 74 microns. Stage two is the desander, handling particles in the 45 to 74 micron range. Stage three is the desilter, removing particles from 15 to 45 microns. Stage four is the centrifuge, addressing ultrafine particles below 15 microns. Each stage depends critically on effective upstream removal. If the shaker fails to remove coarse solids, the desander and desilter quickly overload, centrifuges see excessive wear, and the entire system’s effectiveness degrades. Aipu Hunter series shakers, with their proven separation efficiency, ensure that this hierarchy functions as designed.
Flow Path and System Integration
On a drilling rig, drilling fluid flows from the wellbore through the shale shaker first, then to the sand trap and downstream equipment. This flow path means that all returning mud passes through Aipu shakers for primary solids removal. Shaker discharge—the cleaned mud—feeds into subsequent processing stages. Shaker screen selection must balance throughput against the requirements of downstream equipment. Aipu engineering team helps customers design balanced systems where each stage’s capacity matches the overall circulation rate.
Matching Equipment Capacities
A balanced solids control system requires that each stage can process the full circulation rate. Aipu shakers with capacities from 50 to 420 cubic meters per hour cover the range needed to match any downstream equipment configuration. Progressive solids removal—starting coarse and finishing fine—requires the shaker to remove the bulk of solids mass, typically 60 to 80 percent of all drilled solids in terms of volume. This heavy loading demands robust equipment that Aipu provides.
System Optimization Benefits
When all stages work together effectively, the benefits compound: cleaner mud at each stage reduces downstream equipment loading, extending service life and reducing maintenance. Each stage removes its designated particle size range, achieving optimal overall solids control. Aipu 15-plus years of experience supplying complete solids control systems—not just shakers—provides the system-level perspective that helps customers optimize their entire solids control operation.
