mvzm-on TIIIIIIIIIIIIII/I; 11/11 eoda] e Ma Ck [z n J] ATTORNEYS United States Patent" O F'Low BALANCE REGULATOR AND ADJUSTING SYSTEM non 01m CONCENTRATING'TABLES Theodore Macklin," 1a., Sacramento, Califi, assi'gnor'to Macklin' Equipment Company, acorporation of California This invention relates to ore concentrators and repre sents improvements over Patent No. 2,496,025 to Joseph Stephan, particularly with respect to the construction of the concentrating tableitself, rather than to the mounting and agitating mechanism of such table.
The present invention aims to improve the concentrating action, lessen the cost of operation and construction, and make the table suitable without change of construction for different ores and conditions of operation by the following modifications of, and additions to, the original table structure; namely:
1. A means to permit proper spreading of the feed on the deck of the table'so as to allow the table to handle a maximum volume of solids with a minimum volume of water.
2'. A means to allow of a straight flow of the main pulp stream along the deck of the table without any cross wave or other interference with the flow.
3. A means to keep the main pulpflow moving along the deck from passing onto the laterally upwardly sloping area of the table, or to keep the main pulp flow from passing over said area beyond the point (in lateral movement) where the desired separations must be made.
4. A means to keep the pulp flow oif said sloping area.
without the formation of any cross waves, while permitting of the unrestricted lateral movement of the concentrates to the point of lateral discharge.
5. A means to cause the speeding up or slowing down of the heavy mineral particles as may be desired, so that a wide range of concentration ratios may be realized.
6. A means to segregate two or more selectiveconcentrates from a single pulp mass, according to their characteristics, and draw off such concentrates from the table separately.
7. A means to produce a middlings or separate concentrate of partially looked mineral, and drawing such middlings oif separately.
8. A means to feed a relatively small volume of water to the table in initially separated relation to the pulp feed and in such a manner that such water washes the concentrates before they are delivered to the launder, and so that the visibility of such concentrates is unimpaired to the operator; enabling operational adjustments-if necessary-to be readily made while the concentrator is in operation. 7
It" is also an object of the invention to provide a practical, reliable, and durable flow balance regulator and adjusting system for ore concentrating tables, and one which will be exceedingly effective for the purpose for which it is designed.
These objects are accomplished by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.
In the drawings;
1' is a plan view of the improved concentrator table.
2,738,071 Patented Mar. 13, 1956 Fig. 2 is an enlarged transverse section on line Of Fig. 1.
Fig. 3 is an-enlarged transverse section-on-'line3 -3 of Fig. 1.
tFig. 4 is an enlarged discharge end elevationof the ta le.
Fig. 5 is an enlarged fragmentary longitudinal section on line 5-5 of Fig. 1'.
Referring nowmor'e particularly :to thedrawings and to the characters of reference marked thereon, the table which is mountedgen'eraHy as shown in the above identified patent-comprises arectangular bottom deck 1 formed at its forward or feed end with a relatively short upward slope 2. A continuous sidewall 3 projects upwardly from the deck on one side thereof. On-the other side, however, the upstanding wall 4'only extends a relatively short distance from the feed end, the deck being also provided on said other side with a depending flange 5 which extends from therear end of 'wall' 4 to the discharge end 'of the deck. A gutter or launder 6for the concentrates is secured to and projects la'terallyout fromflange 5.
The deck is covered from end to end with a working face unit F which comprises a thin plate 7 of sheet metal, on which is secured a sheet of thicker rubber 8;
Within the forward or hopper portion 9 of the deck, the sheet 8 is formed with a plurality of transverse grooves 10, preferably set at a slight rearward angle from wall 3, while transversely disposed rods 11 are mounted ina horizo'ntalrow over the grooved portion of the sheet Sin spaced relation thereto a relatively short distance.
Beyond the hopper portion 9 and the grooves 10' the sheet is formed-with along row of transverse grooves '12 disposed in evenly spaced relation from adjacent grooves 16 to adjacent the discharge end of the deck and set at arearwa'rd anglefrom side wall 3 ofapproximately 22 to .said Wall, or to the longitudinal plane of the deck. These grooves 12 extend from side to side of the deck, to all discharge into the launder 6, while the grooves 113' terminate some distance from" the Wall 4.
The hopper 9 is separated into'two longitudinally extending areas by a divider 13 upstanding from the deck and extending-from the forward end of the table to adjacent the foremost groove 12. This divider is'dispos'ed acornpa'ratively short distance from wall 4, as compared with the distance from wall 3, and while it may be fixed, said divider is preferably made so as to be laterally adjustable by means of supporting brackets 14' which are adjustable across the deck; as shown. The rods 11' are secured at one end against the wall 3,and at-the other end slidably project through the divider, which supports them adjacent said other end thereof.
A deflector unit 15 is hingedly mounted on the'inner face of wall 4 intermediate its ends, and extends inwardly in a rearward direction at an adjustable acute angle, as shown; said unit including a longitudinally adjustable blade 16. Another relatively small and similarly angled but'fixed deflector 17 projects laterally inward fromthe wall 4 rearwardly of the deflector unit-16 and adjacent-the forward end of the launder 6;
Along a line 18 adjacent and parallel to, but laterally inward slightly from, the divided-13, and forthe length of the rowof slots 12, the sheet metal plate '7 of the working face unit F is deflected upwardly from said line" to the adjacent side of the table at a relatively small angle to the deck 1, as shown at 19. Said upwardly deflected portion of the plate is formed with a depending skirt 20 which projects into the launder 6 inabutting relation'to the adjacent portion of the flange 5, to which it is secured-for vertical adjustment bysuitable means, such as bolts 21 engaging vertical slots 22 in the skirt (seeFig. 3).
