CSI-D4 Cyclone Pro™ Vertical Cuttings Dryer

What is the CSI-D4 Cyclone Pro™ Vertical Cuttings Dryer?

The CSI-D4 Cyclone Pro™ Vertical Cuttings Dryer is a high-capacity drilling waste management system designed to recover valuable drilling fluids while reducing the moisture content of drill cuttings generated during oil and gas drilling operations.

Manufactured by Astec Industries, the Elgin Separation CSI-D4 uses patented dual-drive technology to maximize fluid recovery, reduce waste disposal costs, and improve solids control performance in both oil-based and water-based drilling fluid applications.

Unlike conventional vertical cuttings dryers, the CSI-D4 Cyclone Pro allows operators to independently adjust both rotational G-force and solids residence time to optimize performance for changing drilling conditions.

Applications

The CSI-D4 Cyclone Pro™ is commonly used by:

Oil and gas drilling contractors
Solids control service companies
Waste management providers
Drilling fluid companies
Offshore drilling operations
Onshore drilling operations
Environmental remediation contractors

Typical applications include:

Drill cuttings dewatering
Drilling fluid recovery
Waste volume reduction
Oil-based mud (OBM)
Water-based mud (WBM)
Synthetic-based mud (SBM)
Solids control systems
Waste management packages

CSI-D4 Cyclone Pro™ Features

Perfect Solution for Managing Water-Based and Oil-Based Waste Cuttings

Engineered Flites

Various blade materials and coatings available
(Tungsten and Hard Chromed)

Screen Design

Fully TIG welded and
hard chromed screens help extend screen life as long as a year

Spray Bar

Integrated spray bar installed in the conical launder section assists in moving recovered centrate thru the system

Conical Launder

Access Hatch

Three hatches located around the body for cleaning of the solids discharge section and maintenance

Common Waste Management Challenges

Drilling operations generate large volumes of wet drill cuttings that increase disposal costs, reduce drilling fluid recovery, and create environmental compliance challenges.

The CSI-D4 Cyclone Pro™ helps operators:

Recover expensive drilling fluid
Reduce waste disposal volumes
Lower transportation costs
Improve drilling fluid recycling
Reduce environmental impact
Support regulatory compliance
Maximize solids dryness

Frequently Asked Questions

What is a Vertical Cuttings Dryer?

A Vertical Cuttings Dryer separates drilling fluid from drill cuttings using centrifugal force. The recovered drilling fluid can be returned to the active mud system while drier solids are prepared for disposal or additional processing.

What drilling fluids can the CSI-D4 process?

The CSI-D4 Cyclone Pro™ processes:

Oil-based drilling fluids
Water-based drilling fluids

without requiring conversion kits or screen changes.

How dry can the cuttings become?

Depending on drilling conditions, the CSI-D4 can reduce liquid content below 4%, with some applications achieving approximately 1%.

Why is the dual-drive system important?

Elgin’s patented dual-drive system allows operators to independently adjust G-force and solids residence time, helping maximize drilling fluid recovery while optimizing solids dryness for changing drilling conditions.
