What Is a High Capacity Shale Shaker? – The Complete Guide

A high capacity shale shaker is a solids control device engineered to process exceptionally large volumes of drilling fluid—typically exceeding 350 cubic meters per hour—while maintaining effective solids separation. Aipu Solids Control has developed its high capacity shale shaker line through over 15 years of manufacturing experience, addressing the needs of deep drilling operations, large-diameter hole sections, and high-rate drilling programs where standard shaker capacity is insufficient.

What distinguishes a high capacity shaker from a standard model begins with screen area. While standard single-deck shakers typically provide 2 to 3 square meters of effective screening area, high capacity models incorporate multiple decks and larger individual screen panels. Aipu’s high capacity offerings include the Hunter-MG4D double-deck configuration with 5.4 square meters of effective screen area per unit, and the Hunter-MG4T tandem configuration that combines two double-deck units for a total of 8.1 square meters of screening area. This expanded area, combined with optimized flow distribution that uses all available screen surface, enables processing of the high flow rates characteristic of large-diameter surface hole sections and high-rate drilling programs without compromising separation quality.

Vibration technology in high capacity shakers must be engineered for the increased mass of larger screen decks and higher cuttings loads. Aipu equips its high capacity models with premium vibrating motors from Ital-Vibras, Martin, and Oli selected and matched in pairs for the specific model and application. These motors operate at 6.0G to 7.5G of acceleration, generating the aggressive vibration needed to convey heavy cuttings loads efficiently while maintaining fluid drainage through the screen panels. The basket structure, validated through finite element analysis, is designed to maintain rigidity under the combined weight of large screen decks, fluid loads, and high-G vibration. Adjustable deck angles from minus 1 degree to plus 5 degrees on each deck provide independent control of cuttings conveyance and fluid retention time.

High capacity does not mean compromised separation quality. Aipu high capacity shakers are compatible with API 40 through API 200 screens in both stainless steel and composite frame options, supporting fine screening applications even at elevated flow rates. The quick-change screen system enables routine screen replacement without extended downtime. Progressive screen configurations—placing coarser screens at the feed end with progressively finer screens toward the discharge—optimize both capacity and separation quality. Manufactured in Aipu’s 50,000 square meter Xi’an facility under API Q1 certified quality management, every high capacity shaker undergoes factory acceptance testing to verify that both capacity claims and separation performance meet specifications. Equipment proven in more than 30 countries validates that Aipu high capacity shakers deliver the throughput that large-scale drilling operations require, with the solids control quality that well programs demand.
