Beit known that I, CLEOFAS GALVAN, a citizen of Mexico, residing at Zacatecas, in the State of Zacatecas and Republic of Mexico, have invented new and useful Improvements in Concentrators, of which the following is a full, clear, and exact description.
My invention relates to machines for concentrating ores and other substances, and has for its object to provide a comparatively-simple and readily-adjustable machine for the above-indicated purpose.
The invention will be fully described hereinafter and the features of noveltypointed out in the claims..
Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the gures.
Figure 1 is a sectional elevation of the improved concentrator. Fig. 2 is a cross-section thereof on the line 2 2 of Fig. 1. Fig. 3 is a detail sectional plan on the line 3 3 of Fig. 1. Fig. 4 is a detail sectional View of an eccentric forming part of my machine and the mechanism connected therewith, and Fig. 5 is an enlarged elevation, with parts in section, of the means for adjusting the concentrating-table vertically. l
The improved ore-concentrator consists of two principal parts-viz., a stationary sepa? rator, in which the material is subjected to the action of a blast, and a vibrating concen.
trator-table. p Y
The apparatus isV provided with a hopper 1 for receiving the ore or other material to be concentrated. The hopper tapers toward its lower end and is provided thereat with a valve 2, adjustable by means of a screw 3 to vary the size of the outlet, and consequently the amount ofv feed. A glass pane 4Apermits of watching the feed.
5 designates an air-sup ply channel connected with a blower or any other apparatus for producing a blast. The supply of air may be regulated by means of the gate or valve 6.
The air passes into a Achamber 7 and against a deiiector 8, which throws it upward against the horizontal gauze or perforated partition 9, whereby the air is divided into a number of streams. These streams pass into the chamber 10, located in the rear of the hopper 1,
receive between them rollers 16.
and then into a series of narrow channels 1l, extending forwardly Vunder the outlet of the hopper in a substantially-horizontal direction. The channels terminate at a point located approximately over the center of the concentrator-table.
The concentrator-table l2 is provided at its sides with inclined flanges 13 and at one end with a channel 14 to receive the concentrates. The table has spaced tracks 15, adapted to One of these rollers is carried directly by a rack 17, which is vertically adjustable in a suitable post 18 by means of a pinion 19, a pawl 2O serving to hold the rack in position after adjustment. 21 is a crank for turning the pinion 19. The other roller 16 is carried by a rod 22, which is vertically adjustable upon an arm 23, extending from the rack 17. The adjustment may be effected, as shown, by means of nuts 24, screwing on the rod 22 and engaging the arm 23 on each side, while the rod passes through said arm loosely. It will be understood that by raising the rod 22 more or less the concentrator-table 12 may be inclined more or less toward the concentrates` channel 14. The rack 17 carries a bearing for a pulley 25, which is driven by means of a belt 26 from the pulley 27, journaled in a stationary bearing 28. The pulley 25 is provided with an axial guideway 29, in which is adapted to slide a block 30, adjustable in said guideway by means of a screw 31, which also turns in a relatively-stationary part of thel pulley. To the block 30 is swiveled a g sleeve 32,through which passes a rod 33, pivoted at 34 to a lug 35 on the concentrator-table 12. A set-screw 36 is used for fastening the rod 33 in the sleeve 32 after adjustment. It will be understood that the rotation of the pulley 25 will cause the concentrator-table topressed against the belt or withdrawn Vthere- IOO from-t0 preserve a uniform tension of the belt. As shown, the tension-rolleris mounted at the end of a rack 37, slidable horizontally in the post 18 and engaged by the pinion 19, the same being Wide enough to en gage both the rack 17 and the rack 37 Obviously, however, two separate pinions might heemployed, and in this case the two racks would not need to have teeth of the same size.
The operation ofthe machine will be readily understood. The ore issuing from the hopper is subjected to the action of the airblast, which throws the lightest particles of material far enough to clear the concentratortable, and the blast, instead of being an unbroken stream 0r current, consists of a series of jets, which act much more thoroughly 'toy y vThat por-` tion of the material which fallsl upon the taseparate and grade the material.
Also the proportion of material reaching the table can bealtered by varying the distance between the outlet of the blast apparatus and the table. In all positions of the table, however, the tension of the driving-belt will be kept constant. v
I desire it to be understood that l do not restrict myself to the exact construction shown r frame adjustable vertically toward and from of the pulley, a driving-pulley journaled in stationary bearings, a -belt connecting the driving-pulley With-the pulley on the frame,
a tension-pulley for saidv belt, and an adjusting device for said tension-pulley, operated by the adjusting movement of the table-supportingvframe.
