The principle of jig concentrator generally is layered according to the proportion or density of mineral and then the light and heavy minerals are discharged respectively Company Profile; Service; Video Center; Gallary; Product Jig Separator Jig Machine LTP34/2 Jig Separator LTA1010/2 Jig Separator 2LTC 912/4A Jig Concentrator JT1070/2
·The spiral classifier recently has emerged as the most effective gravity separator since its introduction The spiral separator also known as spiral concentrator continues to be the most effective gravity separator useful in processing a wide variety of minerals such as coal iron chromite gold zircon and other heavy minerals ores [1 2] The popularity of the
Spiral Test Plants Multotec s heavy mineral spiral test units are supplied by pumps driven by variable speed drives operating between 380 V or 525 V and processing up to 20 tons per hour English KB Letter A4
·Principles and Methods of Gravity Separation Gravity separation processes can be broadly categorized into four main types Heavy medium separation Baths cyclones etc Spiral Concentrators Development of spiral concentrators started in the early 1940 s with the introduction of the Humphreys spiral This was initially used in
·The shape and working principle of the spiral chute and the spiral concentrator are basically the same but they are different in structure performance and use The main differences are as follows ① The bottom section line of the spiral concentrator is a parabola or part of an ellipse while the bottom section line of the spiral chute is a
·The slurry was fed to the spiral via a distributor with an overflow pipe to maintain a constant feed rate into the spiral This was a closed circuit spiral test with a sump and pump During each test the spiral was run until steady state conditions were reached before taking the relative density RD measurements at the top of the spiral rig
·We find that introducing a trench into the channel cross section a feature often used in commercial spiral particle separators leads to a smaller radial width of the particle rich region sharper focusing of the particles which is consistent with experiments showing that channel geometry influences particle separation in a spiral
·In this section an attempt has been made to study the effect of splitter position on the separation efficiency of the spiral concentrator The expression used for calculating separation efficiency E s is given as Barari et al 1979 5 E s = R v R g where R v is the recovery of valuable mineral and R g is the recovery of gangue mineral A splitter located on
·Spiral concentrators have been widely used in coal preparation plants in Illinois and elsewhere to clean 1 mm ×150 μm particle size coal fraction The major factors which have made spiral concentrator so popular include its low capital and operating cost
·Fig 2 shows a snapshot of the particle separation in the HSC simulation The dust stream first reached the discharge at t ∼ 10 the particle flowed downward mineral particles with high specific gravity were found to be present in the inner region of the conduit whereas the gangue particles which have lower specific gravity remained toward the outside
·Spiral separator or spiral chute especially sand mining in the seashore riverside sand beaches and streams Spiral chute is a device that combines the characteristics of spiral concentrator spiral chute shaker table and centrifugal concentrator It is the best gravity separation equipment for placer ore mining and beneficiation
Spiral concentrator is one of the flowing film concentrators and is used for beneficiation of fine coals ranging in size from 3 mm Spiral concentrator Fig consists of a descending spiral launder of a helical conduit with a modified semicircular cross section wrapped around a central supporting column
The detailed separation principle of spiral concentrator is reported in the literature [22 24] The main process parameters of a typical spiral concentrator are the feed flow rate feed pulp density and splitter position which influences the performance in the process [22 26] The performance of the spiral concentrators with different
