Concentrador Falcon VS Knelson

Concentradores centrífugos are essential equipment in metal mines for efficient mineral separation. They are widely used in metal mines at home and abroad, and generally have horizontal and vertical types. The disadvantage of both types of centrifugal concentrators is that they can only produce intermittently, which reduces the efficiency of mineral processing. Some companies have designed a composite vertical centrifugal concentrator to meet the requirements of large-scale, automatic, and continuous beneficiation work. Both Falcão e Knelson concentrators dominate the market with their advanced gravity separation technology. Here’s a detailed comparison.

★ Applications

The Falcon centrifugal concentrator manufactured by Falcon Concentrator is a kind of high-efficiency centrifugal separation and beneficiation equipment selected by metal mines for mineral separation using centrifugal gravity beneficiation technology. It is suitable for gold, silver, and platinum group metals and other valuable metals in terms of particle size. It can be recovered from fine metal ore or other solid materials with finer particle size; it can also be used to sort fine raw coal. The centrifugal separation effect when sorting fine coal with higher sulfur content is far more prominent than that of conventional flotation.

★ Highlight

The high-power “enhanced gravity” feature produced by the Falcon centrifugal concentrator realizes the rapid separation and stratification of fine mineral particles of different density levels, which reduces the lower limit of traditional gravity separation in a large range, and can effectively and quickly process fine-grained mineral particles. Due to the high degree of automation, the operation is simple and fast. It has the advantages of a large sorting range, a large processing capacity, a short sorting cycle, low water consumption, low personnel input, low investment cost, and operating cost, making it available in various fields worldwide. Extensive user approval and production applications.

★ Types

Atualmente, a Falcon tem FALCON SB série, FALCONC series, and FALCONUF series, which are respectively suitable for the separation and production of gold, tantalum-niobium, and tungsten ore.

★ Product structure

O componente central do concentrador centrífugo da série Falcon SB é o cone de enriquecimento do tambor do mecanismo de seleção, que é principalmente um tambor interior de plástico vertical resistente ao desgaste e à corrosão. A parede interior lisa da parte inferior é um cone oco invertido. Existem várias ranhuras em anel côncavo-convexas distribuídas na parede interna do tambor rotativo, e a parte inferior da ranhura do anel está uniformemente disposta com orifícios de água de retrolavagem, de modo que a água de retrolavagem pode entrar no leito solto na ranhura do anel côncavo-convexo através dos orifícios de água de retrolavagem durante o processo de classificação. Realizar a separação e classificação de minerais sob a ação combinada da força centrífuga e da água de recuo.

★ Applications

Knelson Concentrators is a centrifugal reselection equipment developed and produced by Canada Knelson Reselection Solutions Company. As early as 1978, the product began to be commercially used. After continuous development and improvement, it has now formed two categories of intermittent and continuous types. There are more than 20 specifications and models of series products. The single processing capacity is from a minimum of 0.9 tons/hour to the maximum. Up to 650 tons/hour, it meets the capacity requirements of various production scales from laboratory beneficiation experiments, semi-industrial production, to industrial production. Up to now, Knelson centrifugal concentrators have accumulated more than 3,500 installations, and they have been successfully applied in more than 70 countries around the world.

★ Types 

The knelson centrifugal concentrator is designed and developed into two types of products: discontinuous discharge type e continuous variable discharge type. These two types of products are selected according to the yield of concentrates after separation. Different products are selected for different concentrate yields. The yield of concentrates is usually 0.1% as the dividing line. The yield of concentrates below the dividing line is less than 0.1%. Consider using intermittent rows. The ore type and the continuously variable discharge type can be used when the concentrate yield above the boundary is greater than 0.1%.

★ Highlight and Product Structure

The core component of the Knelson centrifugal concentrator is the drum enrichment cone of the sorting mechanism, which is a vertical concentric double-walled cone rotating at the same speed with backwashing water holes on the inner wall, and the discharge port is set at the bottom center of the inner cone. Under the action of recoil water, it can automatically discharge ore. A recoil water storage cavity is formed between the outer cone and the inner cone of the double-walled cone. According to different models and different processing capacities, the inner side of the inner cone is provided with different numbers of continuous, equal-spaced, and equal-depth concave-convex trapezoidal grooves. The bottom of the grooves has backwash water holes designed and arranged according to certain size and quantity requirements. The structure of the Knelson centrifugal concentrator also includes the slurry supply part, the tailings discharge device, the backwash water filtration and supply device, the drive transmission system, the automatic control system, and the vibration-damping frame support structure.

Comparison Summary

Conclusão

In conclusion, both Falcon and Knelson centrifugal concentrators offer advanced gravity separation solutions tailored to different mineral processing needs. Falcon concentrators excel in fine particle recovery (gold, PGMs, coal) with their enhanced gravity technology and automated operation, while Knelson models provide unmatched versatility across production scales (0.9-650t/h) with specialized batch/continuous discharge options. The choice ultimately depends on your specific requirements: For high-efficiency fine mineral recovery with lower operating costs, Falcon is ideal; for large-scale operations needing adaptable discharge systems, Knelson’s proven global installations make it a strong contender. Both systems significantly improve upon traditional gravity separation, delivering superior recovery rates and reduced processing limits for modern mining operations. Always consult with mineral processing experts to determine the optimal solution for your ore characteristics and production goals.
