THOMAS ROWLAND JORDAN, OF NEW YORK, N. Y., A SSIGNOR TO THE ANGLO-AMERIOAN REDUCTION COMPANY, OF SAME PLACE.
ORE-DRIER.
SPECIFICATION forming part of Letters Patent No. 613,518, dated November 1, 1898.
Application filed August 27, 1397. Serial No. 649,736. (No model.)
To all whom it may concern.-
Be it known that I, THOMAS ROWLAND J OR- DAN, a citizen of Great Britain, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in the Treatment of Auriferous and other Ores; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to the treatment of auriferous and other ores and sands for the extraction of precious metals therefrom, and is directed to improvements in appliances for drying the crushed ore, -with the object of largely increasing the capacity of. such machines and effecting the extraction of moisture at a minimum cost.
The nature of my invention will become clearly apparent from a reading of the following detailed description when taken in connection with the accompanying drawings, in which- Figure 1 is a vertical sectional view of my improved drier, and Fig. 2 is a sectional view on the line 2 2 of Fig. 1.
Referring to the said drawings by letter, A denotes a casing having an inner chamber preferably circular in cross-section and increasing in diameterto its upper end. This chamber is open at its lower end and communicates with discharge-chute I), having a hopper-shaped upper end. Near the upper end of the casing is a hopper b for receiving the material to be treated, said hopper. leading into the chamber.
0 is a pipe communicating with the base of the chamber for supplying the heat, and from the upper end of the chamber leads a stack d for carrying off the gases.
The sides of the chamber are lined with fireproof material, and from said sides project inwardly a series of inclined annular flanges e e, which are preferably formed integrally with supporting-rings e e. Centrally of the chamber is a vertical spindle f, provided near its lower end, below the chamber, with a bevel-gear f, which meshes with a bevel-gear f operatively connected with a suitable source of power through which the spindle is revolved. Fixedly secured to the spindle are dishes 9 g, the peripheries of which are disposed slightly above the lower edges of the flanges e and are of less diameter than the diameter of the latter. The dishes cor respond in number to the number of flanges and are preferably of the same diameter throughout, the dimension of the flanges be ing changed to provide for the converging form of the chamber.
In practice the ore after being reduced in a stone-breaker, rolls, or other device is fed into the hopper b and falls therefrom onto the center of the uppermost dish g. The dishes are revolved through the spindle, and the centrifugal action causes the material to be gradually and evenly distributed over the dish and finally passes over the periphery and is thrown upon the inclined surface in a well-separated condition, from whence it falls to the next adjacent dish, and the operation is repeated until the lowermost dish is passed, when the material falls into the chute and is by this means carried out of the drier. The pipe 0 is connected, preferably, with the roasting-furnace which is usually employed in connection with the reduction of the ore and the extraction of the values therefrom, and the hot waste gases from said furnace are admitted by said pipe to the bottom of the chamber, from whence they pass around and between the dishes and flanges, raising the surfaces to a high temperature and finally passing out through the stack. The heated surfaces of the dishes and flanges and the high temperature maintained in the chamber result in drying thoroughly the material, which, being in a well-divided condition, is more readily affected by the heat.
It will be seen that by regulating the speed of the spindle and dishes the material may be passed through at any required rate, according to the natureof the material to be treated or the amount of moisture it may contain.
I claim as my invention In the treatment of auriferous and other ores to extract their values, means for drying the particles consisting of a series of dishes heat, and an outlet for the particles, substanto concave throughout and mounted upon avertially as set forth.
