The VC700 Vertical Cuttings Dryer, designed and manufactured by Xi’an KOSUN Machinery Co., Ltd., is a high-speed vertical centrifugal separation unit. Its core function is to efficiently separate and recover liquid phase drilling fluids from wet cuttings generated during drilling operations. It aims to lower total drilling fluid costs, reduce solid waste discharge, and ensure compliance with environmental regulations regarding the fluid content of discharged cuttings.
Role and Function in Drilling Waste Management Systems
In modern solids control and waste management workflows, the VC700 acts as a critical secondary treatment unit. It is dedicated to achieving “Zero Discharge” (Zero-Discharge Site) requirements, directly impacting the costs of Oil-Based Mud (OBM) and waste disposal.
Efficient Liquid Recovery: Utilizing high centrifugal G-force, it effectively separates adhering liquid phases from solid cuttings for superior solid-liquid separation.
Preventing Mud Loss: The unit effectively recovers valuable mud lost due to shaker “mud-over,” rig movements, or screen blinding.
Environmental Compliance: Significantly reduces solid discharge; treated solids can consistently achieve an Oil on Cuttings (OOC) below 3%, meeting stringent environmental discharge standards.
Technical Features and Performance Advantages
The KOSUN VC700 vertical dryer integrates several technical advantages designed for reliable, high-efficiency, and maintenance-friendly field operations in harsh environments:
High-Efficiency Separation: Specifically designed for OBM cuttings recovery. The stable OOC of <3% drastically minimizes the volume of solid waste.
Wear-Resistant Materials: The flights on the internal rotor are coated with tungsten carbide anti-corrosion and wear-resistant material, significantly extending the service life of key components and reducing long-term maintenance costs.
Optimized Maintenance Design: Common wear parts can be replaced directly from the top of the unit without moving the entire machine. Belts can also be changed without relocating any assemblies, greatly reducing downtime.
Wide Applicability: Ideal for OBM cuttings recovery, ensuring valuable mud is returned to the system while fulfilling “zero discharge” mandates.
Economic and Environmental Value
The application of the VC700 vertical dryer is directly linked to the sustainability and profitability of drilling operations:
Cost Savings: By directly recovering expensive OBM and returning it to the active system, it substantially reduces the need for new mud purchases and lowers waste disposal fees.
Environmental Benefits: Facilitates “Zero Discharge” operations, minimizing environmental footprints and helping operators comply with increasingly strict environmental regulations.
The KOSUN VC700 vertical dryer is a technically mature, reliable, and user-friendly solid-liquid separation device. With its high recovery capacity, optimized structural design, and exceptional durability, it provides a safe, compliant, and economical waste management solution for modern drilling, making it an ideal choice for Green Drilling and cost-efficiency.
