Key benefits of mining centrifuges

  • High capacity and efficiency for various material sizes

    FLS centrifuges are designed for high throughput and efficient separation, ensuring that both fine and coarse materials are processed effectively. Whether dealing with coarse coal or finer materials, the centrifuges handle large volumes with ease, reducing water content significantly. Their high G-forces and optimised basket designs ensure maximum dewatering, leading to improved operational productivity.

  • Easy maintenance and flexible operation

    FLS centrifuges prioritise user-friendly maintenance and operational flexibility. Their modular design and quick access to wear components minimise downtime, allowing for easy replacement of key parts like baskets and belts. With a variety of configurations, including both horizontal and vertical designs, these centrifuges adapt to different plant setups and material sizes, ensuring smooth and efficient operation across multiple industries.

  • Proven separation and dewatering performance

    Our centrifuges are engineered for reliable, high-quality separation and dewatering. Whether it’s coal, chemicals, or wastewater treatment, their proven designs – like the VM coarse coal centrifuges or the solidbowl decanter centrifuges – offer superior results. By combining advanced engineering and durable materials, they ensure long-term performance, high solids recovery, and optimised moisture reduction, making them ideal for demanding industrial applications.

  • Reduce need for skilled labour

    We all know the mining industry needs more skilled labour. This lack can make it hard to attract the people you need to run your mineral processing lab, especially when the mine is in a remote location. With their reduced for human involvement, automated laboratories negate that challenge, ensuring a reliable and accurate flow of sample data, regardless of staffing concerns.

Fine Coal Centrifuges

Built with strong material to cope with the toughest mining conditions, our Fine Coal Centrifuges are built to last. Their exceptional wear life increases efficiency, reduces maintenance and replacement costs and produces high-quality dewatered coal in the most cost-effective way. 

Our Fine Coal Centrifuge range includes both vertical and horizontal scrolled basket style machines that use centrifugal force to separate surface water from coal, salt, granulated slag and other chemicals. Benefits include: 

  • Durable construction for a long service life, including abrasion-resistant linings as standard 
  • Feed distributor and scraper scroll improve ease of operation and reduce wastage 
  • Simple maintenance design enables disassembly in order of component wear  
  • High efficiency, high capacity – up to 100 tph through the HFC1300 S2, which achieves the driest possible product 
  • Full customisation of baskets, drive arrangement and drive motor positions 
  • Efficient dewatering, plus low installation and running costs 

Both the FC1200 and HFC1300-S2 centrifuges are designed to process feed slurry through a rotating, perforated basket. As the basket rotates, its G-forces push the slurry against the surface, allowing water to filter through the solids and discharge through the machine's pipes. The scroll, featuring a screw flight design, moves the solids through the basket until they are discharged as dry product. These centrifuges are versatile, capable of accepting feed slurry from various sources, such as thickening cyclone underflow, sieve bend overflow, or fines dewatering screen overflow. They are highly effective at reducing feed moisture from 45–55% to as low as 9–13%, depending on particle size distribution. While the FC1200 emphasizes ease of maintenance and high throughput, the HFC1300-S2 stands out for its high capacity, advanced real-time monitoring, and enhanced safety features, making it well-suited for demanding industrial applications. 

FC1200

The FC1200 centrifuge is designed with a modular structure that allows for easy maintenance, with components such as the basket, distributor, scroll, and carrier disassembled in the order of wear. This setup enables faster repairs and replacements. It features a one-piece disposable basket that simplifies replacement, along with user-friendly features like easy access for belt changes and a re-usable oil filter equipped with a built-in magnet for better filtration. Additionally, the FC1200 is equipped with a blocked filter bypass indicator for added safety. It offers a range of customization options, including various drive arrangements and motor positions, as well as an optional velocity arrester for feed pipes with high flow rates. Performance-wise, the FC1200 boasts a large throat opening and 16 product conveying fins, which significantly improve throughput and dewatering. 

  • Nominal capacity – 50–80 tonnes per hour*
  • Main drive motor – 55 kw
  • Lubrication motor – 1.1 kw
  • Basket diameter – 1200 mm
  • Basket aperture – 0.250/0.375 mm
  • Size – 3060 L x 2365 W x 2360 H mm
  • Weight – 5650 kg
  • Feed size range – -2 + 0.100 mm

Frequently asked questions

FAQs for centrifuges

In mining, a centrifuge uses rotational force (G-forces) to separate materials based on their density. Feed slurry, which is a mixture of solids and liquids, is introduced into a rotating basket or bowl. The centrifugal force pushes the heavier solid particles against the basket’s surface, while the lighter liquids pass through a mesh or perforations. The solids are moved along the basket by scrolls or vibrations until they discharge as dry material, while the liquid is removed through discharge pipes. This method is commonly used to dewater minerals such as coal, reducing moisture content before further processing. 

The primary purpose of a centrifuge is to separate materials based on their density. In mining and industrial applications, centrifuges are used to dewater solid materials by separating solids from liquids in a slurry. This allows for the recovery of valuable solid materials and the removal of water for further processing. 

A dewatering centrifuge is a machine specifically designed to remove moisture from solid materials. It works by applying high rotational G-forces to push the liquid out of the solid particles. Dewatering centrifuges are essential in mining and other industries where the separation of solids from liquids is crucial.

There are several types of centrifuges used in mining: 

  • Basket Centrifuges: These centrifuges have a perforated rotating basket that uses G-forces to separate solids from liquids. They are commonly used for coarse and fine coal dewatering
  • Screenbowl Centrifuges: Combining filtration and sedimentation, these centrifuges have a solid bowl section followed by a screen section, allowing for enhanced dewatering of fine materials
  • Decanter Solidbowl Centrifuges: These have a rotating bowl with an internal scroll to separate solids and liquids through sedimentation. They are ideal for applications involving fine particles or chemical processes
  • Vibrating Centrifuges: These are typically used for coarse coal, where vibrations help move solids through the machine for efficient dewatering 

Each type is suited to specific material sizes and moisture removal requirements.
