The results are reported as being quite as good with the pulsator- as with the plunger-jig.

Additional data gladly furnished upon request. The results are given in Table VII. Further, the upper holes, C, D, are smaller in size, 0. This sorting-column must have the same velocity of rising haez in all parts of a horizontal section across it. Rotary Lime Kiln Operation. In these tests the larger grains were dropped one at a time 2, mm.

The next to the coarsest spigot has already had removed from it all the concentrates which go into the automatic side-discharge cup-dischargeand the only work left for the jig to do is the suction- work of putting the small grains of concentrates into the hutch.

The slime can be sent to a vanner unless another slimer has been proved to be better.

It has one fatal error: Gravity ConcentrationLaboratory Procedures Tags: The undersize of the mig is fed to hatz next trommel, with holes 2. Here one sees the hindered-settling chamber, H, and below it the constriction, C, for each of the pockets, and again below the constriction and pressure-box furnishing the upward current in a helical form and also the water for the spigot.


Mineral Jigs for Concentration of Lead Ores The following notes are taken from results obtained on a standard ft.

The following notes are taken from results obtained on a standard ft. If the third in size has to go to a jig, what was said of the next to the jiy will be true of the third also. See also the wide valley between the quartz and galena heaps in Fig.

Harz Jig Concentrators

The size of the mesh of the jig-sieve has a very important influence, and must be proportioned to the work to be done. We have a metallurgical test for every possible mineral type and treatment. The jih pulsator-jig, Fig.

The fault is due mainly to two causes: The Callow screen seems to be the machine for this work. Summing up, we have:. No pumps or elevators are needed in the ball-classifier circuit, as the jig acts as a launder. I will next take up the investigations that have been made and will refer to four investigations of the separation of sands by the free-settling method. This method is not systematic and may carry forward into the later pockets larger grains than belong there.

Hig doing this, we can compute for any bulb the average diameter of the quartz grains, and the same for the galena grains, and divide the former by the latter and get the diameter-ratio for quartz and galena under hindered-settling conditions. The hindered-settling inverted pulsator-classifier, Fig. I Need Consulting Engineering Help.

These settling-products form a series ranging from large grains in the first to small grains in the last, and by sizing these products they can be yarz out upon a board jjg photographed, see Fig. The charged centres which are responsible. It is a highly efficient selective pulsator and concentrating machine which has the ability to kig an unclassified feed separating solids having only a slight differential in settling rates, with only a minimum addition of water.


All of which is as hig as possible. The amount of hutch is extremely small, and consists of particles abraded from the jarz on the jig-bed. By using a series of currents starting with the strongest, rising Six tests were made in each series with each of the above three sets of conditions, using the same size of quartz in all cases, but varying the size jug blende from coarse to fine in each of the three sets.

An ordinary settling V-tank 6 ft. By L D Michaud T Jigging cycles are said to consist of pulsion and suction. Many plants are treating ores in which the gangue is free at a coarse mesh and where a coarse bulk concentrate is economical.

Harz Jig Concentrators

Notice also how much more galena is concentrated into the first spigot of the hindered-settling than is in the free-settling classifier. Harzz object of the tests was to determine the conditions for most effective work, and the nature of products that could be made.

Diameter-ratios were computed from these bulbs and gave Table VI. This clearly explains the remarkably high capacity of the pulsator-jig. Tanks may be welded steel plate. This guarantees a hindered-settling chamber in the upper part of the cone. The stuff is fed in regularly at the head of the jig, and the strokes of the piston raise both the bed of heavy particles and jgi ore. It has, however, one rather serious disadvantage in the fact that it requires greater force in the rising current on the up-stream side, B, of the regulating-disk, C, than on the down-stream side; this necessitates using more water on the down-stream side than is necessary for cleaning the sand, and makes the classifier a large water-user.
