DON O. MARKS, OF LOS' ANGELES, CALIFORNIA, ASSIGNOB, OF ONE-HALF TO LYNN S. ATKINSON, OF COLORADO SPRINGS, COLORADO.
CEN'I'RIFUGAL-IMPACT PULVERIZER.
Specification of Letters Patent.
Application filed May 23, 1907.
Patented Jan. 24, 1911.
Serial No. 375,345.
To all whom it may concern:
Be it known that I, DON OTTO MARKS, a citizen of the United States of America, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Centrifugal-Impact Pulverizers, of which the following is a specification.
An object of this invention is to provide a superior machine for disintegrating and pulverizing or reducing frangible materials such as ore, rock, sand, shells, bone, coal, coke, pepper, spices, cofi'ee, grain, fruit, and other substances which it is desired to reduce to a pulp or to a powdered state.
This invention relates to that class of machines in which centrifugal force and impact are utilized to efiect the disintegration and pulverization or reduction of the materials or objects to be reduced. I provide a machine whereby the reduction may be accomplished by application of centrifugal force for driving the material or substance to be pulverized, with great force against a wall suitably constructed and arranged to suddenly intercept the material, and to cause the same to become disinte rated and pulverized or reduced to a pa p or other fine state by the force of its own momentum; means being provided for discharging the product so that the operation of the machine may be continuous.
The device by which motion is imparted to the material 'to be reduced, may be'construoted to operate as a blower by which any dry product will be discharged from the machine, as well as an impeller for the materials or objects to be reduced. a
An object of this invention is to roduce a granular product of any desired neness at the least expenditure of power and time.
A further object of the invention is to provide for frangible substances of great hardness and abrasive qualities a machine that will disintegrate the same with a minimum amount of wear upon the operative parts. This object is attained by providing a rotary head having on its upper face walls extending toward the rim of the head, the front face of each wall being contained in a plane that is radial to the axis of the head. By this construction a maximum expulsive efl'ect with minimum wearing efi'ect is attained.
In carrying out this invention I provide a machine having a rotar device adapted to set up high centrifugal orce in material fed thereto, and to discharge such material with great force against a solid surface whereby the inertia of the particles of the material is made effective to disintegrate or disrupt the object thus impelled .and intercepted.
An object of this invention is to construct an ore disintegrator and pulverizer of large capacity and comparatively small size which maybe composed of comparatively light pieces that may be disassembled from the machine and packed on pack animals on mountainous and other difiicult roads.
A further object is to make rovision whereby the values may be certain y recovered after having once reached the disintegrator and pulverizer.
It may be stated here that in some ores the richest values are found in an im alpable dust which in the processes of disintegrating and pulverizing are carried into the outer air and lost.
An object of this invention is to avoid any such loss. j
The accompanying drawings illustrate the invention.
Figure 1 is a side elevation of an apparatus embodying this invention. Parts are broken away for clearness of illustration. Fig. 2 is a plan of the same, parts being broken for clearness of illustration. Fig. 3 is an enlarged broken plan detail of the disintegrator and pulverizer proper, omitting the cover. Fig. 4: is a fragmental vertical section of the same, on line w:v*, Fig. 3. Fig. 5 is a section on line m w Fig. 3. Fig. 6 is a perspective view of one of the plates forming the intercepting wall.
1 is a frame having a central project-ion 40 and an annular bowl-shaped cavity 2 and provided with a surmounting ring 3 having an octagonal inner wall and a cover 4 forming a chamber 5 in which a rotary device 6 is mounted on a vertical shaft 7 projecting through the central projection and is adapted to be rotated at a very hi h speed by a pulley 8 driven by a belt 9 rom a. pulley 10 on a line shaft 11. Said rotar device is hollow, being composed of a p ain imperforate base plate or head 12, a top plate 13, and projections 14 between'said base plate and top plate and forming impelling wings for impelling the material that may be fed into the space between the plates and also for impelling air which may be admitted freely into said space.
15 is a central inlet through the cover 4 and 16 is a central opening in the top plate 13 to admit into the space 17 above the head 12 the material to be disintegrated and pulverized and' also air to supply the blast for freeing the disintegrated and pulverized product from the bowl shaped cavity 2.
l8 designates plates to form the intercepting faces against which the material expelled from the rotary device 6 will impinge. Said intercepting faces may be variously formed depending upon the character of the material to be reduced. In the drawings said faces are roughened, being vertically corrugated as indicated in liigs. 3, 4 and 6. The corrugated faces 19 t us provided afford a series of intercepting surfaces against which the material may impinge at various angles thereto, in some instances at right angles and in other instances at acute or obtuse angles; the effect being that the material thrown off at a tangent from the rotary-device 6 will impinge upon the surfaces, and owing to the high speed at which the head is rotated and the consequent high trajectory of the object or material, will become reduced to a greater or less degree of fineness by the force of such impact.
Practical use demonstrates that much of the material is reduced to a fine powder, and that some of the material may not be so reduced, and therefore in practical use I propose to use a plurality of machines in train, but as this is customary already with erushers and analogous machines, it is not deemed necessary to show any except the initial machine. It is to be understood that the invention may be embodied in various sizes, and that I do not limit the same to any specific size.
The projections. 14 of the rotary device may be variously constructed. In the drawings, blocks 20 are secured by bolts 21 having their heads countersunk into and passing through the top plate 4 and screwing into the bottom plate 12 and fastened by nuts 22 on their lower ends.
23 is a detachable shoe of U-form adapted to seat on the blocks 20 from the inside. The same may be constructed of such size as to be readily insertible through the opening 16 in the top'plate to rest against the block 20.
*By referring to Fig. 3, it will be noted from the curved arrow that the rotary device is intended to rotate with the hands of a watch and consequently the right wall of the uppermost shoe in the view is the one which will act upon the material fed to the machine. The forward face of each of the protectingshoes 23 of the blocks 20, is therefore the im-- pacting face, and receives whatever wear may result from engagement with the wing of the material fed to the machine. It is important that the forward face of each of the wings 14 shall extend in radial lines,
front face of each wall, so that the horizon-.
tal traces of said face are contained in planes radial to the head, the wearing effect upon such faces is minimized and the expulsive effect upon the material fed to the head is brought to a maximum. In case the shoe becomes worn on its forward face it may be withdrawn, turned upside down, and reinserted, thus bringing a new face to the front.
The head 12 is provided with a flanged hub 24 which projects upward through the face of the head and rounded at the top to form a distributer for the material fed through the central opening 16 of the top plate 13. Said hub also serves to limit the size of the orifice leading into the ways between the wings 14; the purpose being to provide an opening of large capacity but of such size that no object which cannot pass between the top late and the head can lodge on the head. nother object of the distributer is to impart a measure of centrifugal force to the material fed into the opening 16, so that as the material enters the rotary device, such motion is first set up in a measure, thus bringing the material into the path of the wings 14 by which the same is caught and impelled outward at high" speed.
- It is to be understood that I do not limit the inner [wall of the ring 3 to" the octagonal form shown, but propose preferably to use some angular form of inner wall, and that the octagonal form is the form I deem preferable. 25 designates shoulders at the bases of the several corners of the inner wall of said angular ring, the same being provided to support the ends of the plates 18 and to hold the plates at the level of the rotary device. Said plates project inwardly for a considerable distance beyond said shoulders, and a sheer open space 26 is thus provided below'the bottoms of said plates; the purpose being to so construct the machine that the material broken by contact with the inner face 19 of the wall shall fall unobstructed into the bowl 2, the bottom of which slants .to the inclined outlet 27 underneath said wall from which the material operated upon shall be discharged. Such dlscharge is practically effected instantaneously after the disintegrating and pulverizing takes place, and is carried on the principle of a blower.
space at t The product passes throughv the outlet 27, by means of a lateral pipe and a dust-collector 28 is provided to receive the same. By this collector the roduct is finally discharged into a suita le receptacle, as the trough 29,.whence it may be carried for further operations; By rovidin the pulverizer with a blower, an conneotmg the pulverizer with a dust-collector, the values contained in the dust may be delivered into the trough 29 or ,any other suitable receptacle from which they may be carried to the cyaniding tanks or other devices for recovermg the values. The air from the blower will finally esca e from the central dependin outlet 30 o the dust-collector, as indicate by the curved lines shown in Fig. 1'. The lateral pipe 27 opens tangentially into the e top of the body 28 of the dust collector, thus'to cause the material to circle around the depending air outlet 30 whereby the solids are caused to deposit and to discharge through the trou h 29.
The rotary device is etachably mounted on the shaft 7 by means of the flanged hub 24 and a feather 31.
32 desi nates stud screws by which the ,parts of t e head are secured together.
The frame 1 of the device may be of castiron or steel and provided with a step 33 having a socket 34 and a convex plate 35 at the bottom of said socket.
of the shaft? is provided with a hemispheri- 41 is an oil cup and 42 an oil duct cored.
