Four Mini Decanter Centrifuges Ready for a Customer in Europe

GN Separation Supporting Mineral Exploration with Efficient Solid-Liquid Separation

GN Separation is pleased to announce that four mini decanter centrifuges are ready for shipment to one of our customers in Europe, where they will be used for mineral exploration drilling mud solid-liquid separation. This delivery highlights GN Separation’s continued commitment to providing reliable, compact, and high-performance separation solutions for demanding exploration projects worldwide.

Mineral exploration drilling generates large volumes of drilling fluids mixed with fine and ultra-fine solids. If these solids are not effectively removed, they can negatively affect drilling efficiency, increase fluid consumption, and raise disposal costs. For this reason, solid-liquid separation plays a critical role in maintaining stable drilling operations and controlling operational expenses.

The Role of Mini Decanter Centrifuges in Exploration Projects

Mini decanter centrifuges are specifically designed to handle applications where space is limited but high separation efficiency is required. In mineral exploration, drilling sites are often remote, temporary, and constrained by logistics. Compact equipment that can be easily transported, installed, and operated is essential.

Despite their small size, GN Separation’s mini decanter centrifuges generate high centrifugal force, allowing them to effectively remove fine solids from drilling mud. This ensures that the drilling fluid maintains the proper density and viscosity required for stable and efficient drilling.

Application: Mineral Exploration Drilling Mud Solid-Liquid Separation

The four mini decanter centrifuges prepared for this European customer will be used to treat drilling mud generated during mineral exploration activities. The drilling mud serves several key functions, including cooling the drill bit, transporting cuttings to the surface, and stabilizing the borehole.

As drilling progresses, fine solids accumulate in the mud system. If not properly separated, these solids can reduce drilling performance and increase wear on downstream equipment. By using mini decanter centrifuges, operators can continuously remove fine solids, extend the life of drilling fluids, and improve overall operational efficiency.

Advantages of GN Separation Mini Decanter Centrifuges

GN Separation’s mini decanter centrifuges offer several advantages that make them ideal for exploration projects:

  • Compact footprint, suitable for limited space and mobile setups
  • High separation efficiency for fine particles
  • Reduced fluid loss, allowing drilling mud to be reused
  • Lower disposal and operating costs
  • Ease of transportation and installation, especially at remote sites

Each unit is engineered with durability and reliability in mind, ensuring stable performance even under challenging working conditions.

Quality Control and Reliability

Before shipment, each mini decanter centrifuge undergoes thorough inspection and testing to ensure mechanical reliability and operational readiness. GN Separation applies strict quality control standards to guarantee that equipment performs as expected once installed on site.

This focus on quality helps minimize downtime, which is critical for exploration projects where delays can result in significant cost increases.

GN Separation remains committed to innovation, quality, and customer satisfaction, delivering reliable equipment that helps our customers operate more efficiently and sustainably.

 

GN Vibrating Screens for Iron Ore Mining: High-Efficiency Screening Solutions

The domestic iron ore mining industry continues to demand reliable, high-capacity, and energy-efficient screening equipment capable of handling large volumes of material under harsh operating conditions. As iron ore processing becomes increasingly optimized, the role of advanced vibrating screen technology is more critical than ever. GN Separation has developed a range of vibrating screens specifically designed to meet these challenges, delivering consistent performance, durability, and precision.

In this project for a domestic iron mine, GN supplied a combination of one Large Linear Vibrating Screen (GNLSP3073) and four 5-Deck Stack Vibrating Screens (GND5Z1014). This equipment configuration was selected to maximize screening efficiency, improve product classification accuracy, and increase overall plant throughput.

Large Linear Vibrating Screen – GNLSP3073
The GNLSP3073 Large Linear Vibrating Screen is engineered for high-capacity primary and secondary screening applications in mining operations. Its large screening area allows it to handle significant volumes of iron ore slurry or dry material while maintaining stable and uniform vibration.

Key advantages of the GNLSP3073 include:
• High throughput capacity, ideal for large-scale iron ore processing
• Robust structural design, ensuring long service life even in abrasive environments
• Linear motion vibration, which promotes efficient material stratification and rapid separation
• Low energy consumption, reducing operational costs over time
In iron ore mining, where material consistency and uptime are critical, the GNLSP3073 provides reliable performance while minimizing maintenance requirements.

5-Deck Stack Vibrating Screen – GND5Z1014
To complement the large linear screen, the project includes four units of the GN GND5Z1014 5-deck stack vibrating screen. Stack screens are increasingly popular in iron ore beneficiation due to their compact footprint and ability to achieve fine and ultra-fine separations with high precision.
The GND5Z1014 offers:
• Five screening decks, enabling multiple size separations in a single machine
• High-frequency vibration, which improves fine particle separation efficiency
• Compact and modular design, saving valuable plant space
• Polyurethane screen panels, providing excellent wear resistance and longer replacement intervals
By using multiple stack vibrating screens in parallel, the iron mine can process large volumes of material while maintaining tight particle size control. This is especially important for downstream processes such as magnetic separation, flotation, or pelletizing.


Optimized Screening System for Iron Ore Processing
The combination of a large linear vibrating screen and multiple stack vibrating screens creates a highly efficient and flexible screening system. Coarse material is effectively handled by the GNLSP3073, while finer fractions are accurately classified by the GND5Z1014 units. This staged approach improves overall separation efficiency and reduces the load on downstream equipment.
GN vibrating screens are designed with ease of operation and maintenance in mind. Features such as quick screen panel replacement, heavy-duty vibration motors, and corrosion-resistant coatings help ensure long-term reliability in demanding mining environments.
With the supply of 1 unit GNLSP3073 Large Linear Vibrating Screen and 4 units GND5Z1014 5-Deck Stack Vibrating Screens, GN Separation delivers a proven screening solution for domestic iron ore mining operations.
