KREBS - Cyclones - Coal Spirals Concentrator by FLSmidth

Spiral coal concentrators use the specific gravity of materials with different densities to separate coal, and produce a low-ash coal product at high efficiency. Our high-performance Coal Spirals deliver a feed capacity of 2 STPH to 3 STPH (1.8 mtph to 2.7 mtph) per start, dependent on raw coal quality and refuse amount to be discarded

Multotec-designed spiral concentrators are used across the world in coal, gold, iron ore, mineral sands, platinum and chrome processing plants and other minerals. We manufacture a wide range of spiral sizes and configurations that can be optimised to your application. The benefits of the Multotec Spiral Concentrator:

INNOVATIVE GRAVITY-BASED TECHNOLOGIES AND

Spiral Concentrator Application for Ultrafine Coal Cleaning Recent studies have found that spirals such as the SX7 can provide an effective gravity-based separation performance for -100 mesh coal. Required volumetric flow rate is around 15 gpm/start and feed solids content should be nearly 15% by weight. Currently, two U.S. coal

Spiral Separators VS Concentrating Tables

Apr 02, 2018 Spiral concentrators designed for applications in coal preparation operations have a shallower pitch than those used in heavy mineral separation. The typical spiral unit consists of a spiral conduit with a modified semi-circular cross section

A simple process control model for T spiral concentrators

Spiral concentrators are compact, cost-effective and generally efficient gravity concentration separators for a wide range of applications (for example, coal, beach sands, iron ore, chromite and tantalite). Recent research has resulted in the development of mathematical models to predict the performance of spiral concentrators

Evaluate Spiral Concentrator Circuit Performance

Oct 13, 2017 Evaluate Spiral Concentrator Circuit Performance. Circuit analysis can be used to evaluate the overall effectiveness of various configurations of unit operations in mineral and coal processing circuits. This powerful tool, has regretfully seen only limited application in the analysis of coal processing circuits

Spiral separator - Wikipedia

Wet Spiral Separators. Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to

Computational and Experimental Investigation of Spiral

Concentrator Flows. ABSTRACT. Spiral concentrators are used globally in the fine coal processing industIy to segregate particles, by grnvitation, on the basis of density and size. Consisting of an open trough that twists vertically downwards about a centrnl axis, a sluny mix of particles and water is fed to the top of the concentrator

Spiral Offers Better Recovery | Coal Age

Aug 07, 2020 Following years of detailed test work, Multotec said it has successfully developed and proven a new spiral concentrator that eliminates beaching and enhances recoveries in the 1- to 3-mm-size fractions. When compared to traditional spirals, the new SC 25 spiral has shown extraordinarily higher recoveries

Coal Spiral Concentrators | Multotec

Multotec has designed and optimised both single ( SX4) and double ( SX7 and MX7) coal spiral concentrators that are supplied with steel rubber-lined or PVC/polyurethane pipe launder systems. The spiral models each have different combinations and have been developed to suit the coal quality. New research and development has shown that our compact, modular designs have added flexibility when

environment concerns. 4+3 short turns two-staged spiral concentrator has been developed, applied in ultrafine coal cleaning circuit, and operated at a lower flowrate than that of spiral used in fine coal cleaning circuit. Ultrafine spiral concentrator is a specific gravity-based separator

Spiral Concentrators - Mine

Spiral concentrators are normally used in banks of multiple spirals. Typical capacities for spirals run from 1-3 tons per hour of feed for minerals and 3-5 tons per hour for coal. Typical construction of a spiral concentrator is fiberglass and urethane to reduce wear from abrasion. Charles Kubach, Mining and Mineral Processing Engineer
