UNITED STATES PATENT OFFICE. A
Application filed Ma 5,1927. aerial N0. 188,993.
The present invention relates to a machine for finely grinding ore or any other elements and has for its principal object to provide a centrifugal structure for casting the ore against liners for crushing the ore so that the same may drop perpendicularly down on another set of grinding elements of similar construction.
A still further important object of the inte vention lies in the provision of a machine of this nature which will not clog up and in which the centrifugal casting memberfunctions as a flywheel and allows the machine to operate with a minimum amount of enas ergy. v v
A still further very important object o the invention lies in the provision of a grinding machine of this nature with an exceedingly simple construction that is strong as and durable, thoroughly eflicient and reliable in operation, inexpensive to manufacture, and one in which the parts are accessible by means easy to assemble and disassemble and otherwise well adapted to the purflw pose for which it is designed.
With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fullv described and claimed.
In the drawings:
Figure 1 is a vertical sectional view through the machine embodying the features of my invention,
Figure 2 is a top plan view of the revolving casting member,
Figure 3 is an enlarged detail section 4 taken substantially on the line 33 of Figure 2 Figure 4 is a sectional elevation of the machine, and
Figure 5 is a top plan view of the hopper.
Referring to the drawing in detail it will be seen that the numeral 5 denotes a plurality of legs on which is sufpported an outlet hopper 6 of an inverted rusto-conical formation having an annular flange at the top thereof indicated by the numeral 7 and rest- 60 mg on the upper ends of the legs 5. The legs 5 may be supported on a concrete foundation or the like. A casing is disposed above the outlet hopper 6 and is of a stepped formation decreasing in diameter from the bottom to the top. The bottom section of the casing comprises a ring 8 having an outwardly disposed flange at its lower end as at 9 and a similar flange 10 at its upper edge and at said upper edge is further provided with inwardly directed flange l1. Flanges 7 and 9 are bolted or otherwise secured as at 12 to the legs 5. The next section comprises an annular ring 14 smaller in diameter than the ring 8 and having at its lower structure 23. The numeral 24; denotes a conical shaped member formed with annular flanges 25, 26 and 27 directed outwardly therefrom and disposed respectively in sections 8, 14 and 19 of the, casing and decreasing upwardly in diameter as said casing sections. On each of the flanges 25, 26, 27, there is formed a plurality of radiating ribs 28 which rise therefrom and which have bolted thereto wear blocks 29 as is indicated to'ad- 86 vantage in Figure 3. Each wear block 29 has a concave surface for engaging the ore or the like as will be more apparent later. This member 24 is keyed on a shaft 30, the upper end-of which is journaled in a cross head 31 extending through openings 32 in the inlet hopper 23 and avin a shield 34 thereov'er, sa d shield and sai cross head being securely fastened as at 35 to projections 36 on the hopper 23. Suitable antifriction bearings 37 are provided in the cross head to allow free rotation of the shaft, The lower end of the shaft is journaled in a casing 38 having anti-friction bearings 39 therein. This casing 38 extends across the outlet hopper structure 6 as is clearly shown in Figure 4. On the shaft within the easing 38 is a belt pulley 40 for driving the pulley and the shaft. The lower portion of the casing is open and is closed by a removable plate 41.
When the member 24 is revolving in a clockwise direction as shown in Figure 2, and ore or like material is poured into the inlet hopper 23 said material will be cast outwardly by the wear blocks 29 against liners 43 on the interior of the casing sections for crushing the ore and allowing the same to drop perpendicularly into the next section. Thus the ore will be finely ground and there will be very little likelihood of the machine becoming clogged up because of the vertical drop of the material from one section to the other and because of the centrifugal force which will cast the material against the liners. The machine will use little energy in its operation because of the flywheel action of the member 24.- after the same has been started. It will be seen that because of the sectional construction of the casing the various parts are readily accessible and the various parts may be assembled and disassembled with ease. It will also be seen that practically all the wear is taken up by the wear blocks 29 and the liners 43 and that these are the only parts which will have to be replaced under ordinary circumstances durin the life of the machine.
It is thou lit that the construction, operation and a vanta es of this invention will .now be clearly an erstood without a more detailed description thereof. It is important to bear in mind that the cone shaped member 24 enables the increasing diameter of the diflerent sections and thus the ore or pulp drops perpendicularly from one chamber to the other and particular attention is directed to the fact that said ore or pulp always drops into a larger chamber because of the increasing area of the chambers from the to to the bottom which is provided by the increased diameter of the casing sectlons and the corresponding increasing diameter of the flanges on the coneshaped member. It is also to be noted that the changes formed by the sections are in close proximity to each other thus eliminatin pockets or unnecessary space above or be ow, the casting elements formed by the wear blocks. The shaftis adapted to revolve at a hi h-rate of speed and thus the pulp is cause to be held 1n suspension thus eliminating any chance of cloggin It is also to be noted that the number 0 casting elements increases as the diameter of the casing sections increase.
The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of con struction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Havin thus described my invention, what I claim as new is:
1. A machine of the class described comprising a stepped casing forming a plurality of chambers increasing in diameter from top to bottom, a cone-shaped member, means for mounting the cone-shaped member in the casing, a plurality of flanges of annular formation projecting outwardly from the cone-shaped member one in each chamber, a plurality of radially disposed ribs on the flanges projecting upwardly therefrom, wear blocks fixed to said ribs.
