Concentrateur Falcon VS Knelson

Date de publication:04 septembre 2020

Concentrateurs centrifuges 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 Faucon et 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

Actuellement, Falcon a 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

L'élément central du concentrateur centrifuge Falcon de la série SB est le cône d'enrichissement du tambour du mécanisme de tri, qui est principalement un tambour intérieur vertical en plastique résistant à l'usure et à la corrosion. La paroi intérieure lisse de la partie inférieure est un cône creux inversé. La paroi intérieure du tambour rotatif comporte un certain nombre de rainures annulaires concaves-convexes, et le fond de la rainure annulaire est régulièrement doté de trous d'eau de lavage à contre-courant, de sorte que l'eau de lavage à contre-courant puisse pénétrer dans le lit meuble de la rainure annulaire concave-convexe par les trous d'eau de lavage à contre-courant au cours du processus de triage. Réalise la séparation et la classification des minéraux sous l'action combinée de la force centrifuge et de l'eau de recul.

★ 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 et 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

Fonctionnalité Falcon Concentrator Concentrateur Knelson
Discharge Type Mostly batch, some continuous Batch & continuous models
Capacité de traitement Wide range (varies by model) 0.9 – 650 tons/hour
Automation High (easy operation) High (auto-discharge capability)
Best for Fine gold, coal, PGM recovery High-capacity gold & mineral sands
Cost Efficiency Lower operating cost Wide-scale adoption
Key Model Series SB, C, UF Discharge-based (batch/continuous)

 

Conclusion

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.
