Dual Deck Shale Shaker for High Capacity Drilling

High capacity drilling operations with elevated circulation rates and aggressive penetration demand a dual deck shale shaker that maintains separation effectiveness at maximum throughput. The dual deck configuration doubles the available screening area within a single footprint, making it the natural choice for high-volume solids control. Aipu Solids Control provides the Hunter-MG4D dual deck shaker and Hunter-MG4T tandem configuration for the most demanding high-capacity drilling applications worldwide.

Scaling to High Capacity Requirements

The Aipu Hunter-MG4D processes up to 280 cubic meters per hour across 5.4 square meters of screen area, providing a high single-unit capacity that satisfies most land rig and many offshore drilling circulation rates. The premium Ital-Vibras, Martin, or Oli motors deliver up to 7.5G vibration output, maintaining effective solids conveyance and fluid throughput even at maximum rated capacity. For drilling programs exceeding 280 cubic meters per hour, the Hunter-MG4T tandem configuration combines two dual deck shakers in a shared installation, providing 8.1 square meters of total screen area with 420 cubic meters per hour capacity. The tandem configuration can be expanded to three units for 12.2 square meters and 630 cubic meters per hour for ultra-high-capacity drilling operations such as large-diameter top-hole sections or dual-derrick deepwater rigs.

Flow Distribution and Screen Management

Effective high-capacity operation requires proper flow distribution across the full screen width. The Hunter-MG4D feed box includes internal flow control baffles that spread the incoming fluid evenly, preventing localized overloading that would cause screen blinding and fluid loss. At high flow rates, screen selection becomes critical. Aipu recommends coarser upper deck screens of API 40 to API 60 for high-capacity mode operation to handle the bulk solids volume, with API 80 to API 120 on the lower deck for secondary separation. Screen condition must be monitored more frequently at high throughput rates, as screen wear accelerates and hole development can compromise separation integrity. Aipu provides high-capacity operating guidelines including recommended screen mesh ranges, deck angle settings, and motor eccentric weight adjustments optimized for maximum throughput conditions. The API Q1 certified manufacturing ensures that the Hunter-MG4D frame and motor mounts withstand the sustained dynamic loading of continuous high-capacity operation without structural degradation over extended drilling campaigns.
