To all 'whom t may concern:
Be it known that I, WILLIAM E. PEARSE, a citizen of the United States, and resident of the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Separating Processes and Apparatus, of which the following is a specification, taken in connection with the accompanying drawings.
This invention relates to separating processes and apparatus, and relates especially to the process and apparatus for separating ore or similar anular substances, by projecting particles o material of substantially uniform size against an angularly disposed impact surface, and then separating the particles according to their different trajectories, as they rebound from such surface.
In the accompanying drawings, showing somewhat diagrammatically an illustrative embodiment of apparatus for carrying out such a process, Figure 1, is a vertical section,
' Fig. 2, 1s a partial perspective of a divider,
Fig. 3 is a similar view of the target or sec- Fig. 4, is a perspecsimilar view of one rack g Fig. 6 is a perspective view of another form of impact member,
and Fig. 7 shows a sectional detail of the hopper mounting.
The bin 1, which contains thecrushed or otherwise disintegrated material, may be provided' with the pivoted supply gate 4,
controlled by the lever 5, so as to regulate the supply of the material 3, to the chute 2. This material as indicated in Fig. 1, is fed into a suitable kiln 6, of any desired construction, and dried to the proper eXtent,.a furnace, 7, being indicated for this purpose and connecting with a suitable chimney 8. The passage 9, at the lower end of this kiln, may be provided with the control gate 10, which is suitably pivoted as indicated and operated by the lever 11, so as to control the amount of disintegrated material 3, admitted to the screening run-way 12. The screen 13, at the upper end of this run-Way is of relatively iine mesh and may have any desired construction, while the lower screens, 14 and 15 may have progressively larger mesh, so as to properly size the particles in a well known manner, the large particles being discharged if desired from the discharge passage 16.
The particles 3, passing through the screen `working faces.
13, and into the s out 17, are of substantially the same size, alt iough of course, any other desired means of properly sizing the particles, may be employed. From the spout 417, this material is fed into the hopper, 18, which may be adjustably mounted on the top of the bin 25, by the two adjustable clamps 23 and 24, which as is indicated in detail in Fig. 7, are adapted to clamp the top of this bin 25, and rmly hold the ho per in position when the screws 26 are tig tened. This action also forces the wedge shaped clamps 27, 27 together, so that the inner split .clamp 27 is wedged inward, iirmly engaging and clamping the hop er mouth, 18. This allows a very desirab e vertical and horizontal adjustment of the hopper, which serves to regulate its position with respect to the target or im- 1pact member below. The /throat 19 of this opper is controlled by the symmetrically arranged pivoted feed gates 20, which are operated by the levers 21, and when simultaneously operated to the same extent have a-self centering action, so that the opening is always located in the same vertical plane. In this manner, the amount of material fed past the gates may be adjusted, while the ine of feed is maintained constant.
The target or sectional impact member, 22, may be adjustably mounted below the hopper, and as indicated in Fig. 3, the target may be generally wedge-shaped with curved In that iigure, the target is shown as composed of a plurality of members, 28, 29, 30 and 31, each of which is independently adjustable and may be separately secured to and adjusted with relation to the support 323/, by means of the screws 33, which loosely engage the enlarged holes, 32, in the target sections. The support 33 is separately adjustable with respect to the bracket 34,V to which it is held in position by thescrew 37, which passes through the enticles, when projected substantially symmetrically towards the advance edge of the wedge-shaped target is deected laterally in both directions, and also since the working faces of the target are curved, the degree of concavity being even greater than indicated in Fig. 3. with some classes of material, the particles which are deflected laterally from the axis of the stream before striking the target impinge upon a less inclined surface, and thus are deflected after rebounding to practically the same extent. They thus fall into the same compartment with the other materials of the same composition and degree of elasticity, which fell closer to the advance edge of the wedge-shaped target.
Suitable adjustable dividers of any description may be employed to separate the particles having the same trajectories after leaving the target. In Fig. 1, the partitions 63, are indicated within the bin and a series of adjustable dividers, 42 are swivelingly mounted on the enlarged ribs, 43 on the upper ends of these partitions. As is seen in Fig. 2, these dividers 42 may consist of a metallic plate, split at the lower end to the desired extent, so as to form the clamping jaws, 42". The screws, 47 are provided and operate to close these jaws, and hold the dividers in the desired adjusted position with respect to the ribs 43. The blades, 44 may be adjustably mounted at the upper ends of the dividers by the screws 47 engaging the enlarged apertures 45 indicated. In this way, the dividers may be moved angularly into any desired position, so as to be as close to the target or impact member as desired, and also the blades may be moved vertically to a considerable extent as to give further adjustment to separate and collect the particular class of particles desired.
The somewhat larger particles, passing through the screen 14 and into the spout 39, may be treated in a similar manner, passinfy through the hopper 18 where similar fee gates are operated by the levers 21', and a similar impact separator is located within the bin 25". In some instances, especially where larger particles are operated upon, it is desirable to have the target formed with a single curved working face, and arranged at a less angle to the path of the particles, so as to decrease the wear and other objectionable action of larger particles striking it. This arrangement is indicated in connection with the larger particles passing through the screen 15 and into the spout 40. This spout as is indicated, is so shaped as to somewhat decrease the velocity of the particles, and the target or sectional impact member 42 is arranged at one side, so as to make only a `slight angle with the path of the particles. The target sections 43, 44, as shown in Fig. 6 may each be formed with a curved working face, and adjustably mounted on the bracket 47 by the screws 46,which engage the enlarged holes 45 in each section. This bracket is slidably mounted in the block 4S and held by the screw 49. In this instance, of course, any desired number of adjustable dividers 42 may be used to separate the particles after they rebound from the target.
A suitable amalgamator may be arranged to treat the particles issuing from any one or more of the discharge chutes. For instance, in Fig. l, the amalgamator 5() is arranged to treat the particles falling between the two dividers adjacentthe target, such particles preferably passing through a suitable screen 52, and into the amalgamator when the slide 54 is open. A similar screen 53, and slide 55, is shown in connection with an amalgamalor to act upon the relatively non-resilient particles discharged from the target 42. These amalgamators may have any desired construction, and in Fig. 4, the amalgainator racks, 56, are shown as arranged with the amalgamated rods, 57, located in a transverse manner within the casing. Each rack, as is indicated in Fig. 5, may be formed of the side frames 57 and the split end frames 57*JL and 57h, which when forced into position, clamp the rods 57 in an obvious manner.
In using this apparatus on auriferous niaterial, the liner particles after tl ie prel i minary drying and sizing operation, fall in a thin sheet through the centering feed gates 2l), and impinge with the desired degree of force upon the target or sectional impact member, adjacent its advance edge. The quartz particles, by reason of their superior resiliency, are projected farther, as they rebound l'rom the target, and having the Ilatter trajectory and the higher angle of llight, pass over the lirst divider and fall into the outer guide- Ways formed by the partitions. Softer nietallic particles, such as gold platinum or eopper, if copper bearing material is treated, are not so resilient, and arc not thrown so far by their impact upon the target, and so fall into the discharge chutes closely adjacent it. As has been explained, thecurvcd working 'laec of the target, tends to counteract to a considerable extent the accidental deviation of particles from the proper line or path of projection against the target, and it is of course, apparent, that the particles may be projected against the target in other ways than by gravity, and the force of impingement upon the target may in such cases be regulated to the desired extent. Of course, by laterally adjusting the target and hopper, the entire stream may fall to one side of the advance edge of the wedge shaped target, and only one working face would operate in such case, the material all being thrown to one side, but to different extents. lith the adjustable hoppers indicated, the raising of the hopper regulates the extent of -free fall of the particles from the feed gates to the Cri target, and thus adjusts the force of impact and the resulting trajectory ofthe various particles.
