ARTHUR FEUST, OF NEW YORK, N. Y.

APPARATUS FOR DISINTEGRATI NG ORES AND OTHER MATERIALS.

Application filed July 6', 1914, Serial No. 849,200.

To all whom it may concern Be it known that I, ARTHUR FEUs'r, a citizen of the United States, and a resident of the county of the Bronx, city and State of New York, have invented certain new and useful Improvements in Apparatus for Disintegrating Ores and other Materials, of which the following is a Specification.

This invention relates to apparatus for disintegrating ores and other materials.

In the apparatus hitherto devised for the purpose, a tumbling barrel was used which was rotatable about an axis arranged in a general horizontal direction, and capable of being tilted to various degrees of inclination to the horizontal. This barrel was provided with-an inlet opening of suitable character, through which the material to be treated was introduced, and with an outlet opening at the axis of the barrel, through which the ground or disintegrated material was discharged. In the devices hitherto used, it was considered essential that the shape or form of the barrel, backward from the outlet opening, was that of a cone, and that the said outlet opening be at the apex thereof. Backward from the base of this cone, or conical outlet portion, the barrel was formed either cylindrically or conically or both, and the inlet opening in this portion was placed to receive the material to be disintegrated.

My invention consists in having the inner surface curved so as to cause an etlicient triturating action, and it has certain definite advantages over the prior forms described, and my inventlon is shown 1n the accom- .panying drawing, and will be more fully described hereinafter and finally pointed out iln the claims.

In the accompanying drawing, Figure 1 is vertical section with parts in elevation, and also shows an uninterrupted curve at i the interior of the barrel, and l? ig. 2 is a diagrammatic View intended to show the mode of operation of the invention.

Similar reference numerals indicate corresponding parts throughout the various figures of the drawing.

Referring to the drawing, and more parwith end members 11 and 12, each of which is provided with a bearing 13 and 14: for the purpose of supporting'and guiding the inlet and outlet portions of the barrel. The barrel 15 has at'its' portion of largest diameter Specification of Letters Patent.

an embracing gear-wheel 16 which meshes with one of several pinions, not shown. The

pinions are driven by suitable means, and

they in turn drivethe gear-wheel 16, where- ,by the tumbler 15 is moved around its axis and. causes any material therein to be tumbled about. This driving mechanism is well known and is not described in detail.

The inlet end 20 serves to receive the material to be disintegrated, and this material, which is indicated by 21 in-Fig. 1, slides along the spherically curved interior surface LO of the tumbler 15. The larger parts of the material gradually gather in the central part of the tumbler, and the weight of these large; portions serves to add to the crushing action which is carried on.

ried forward and are gradually raised on the ascending side of the barrel, during which they are sub ected to a continuous crushing As these parts are gradually crushed, these pieces are caraction, as well as to a triturating action, and their subsequent backward travel in proportion to their different sizes, materi-' serves to gradually move the material to be disintegrated into the position or strata where it is subjected to the greatest crushing force, and by the continued rotation of the barrel 15 by means of suitable mechanism, as for instance as indicated by 16, the material is gradually moved along the curved ascending portion 413, which, in embodiment shown in Fig.1, is parabolic. The parabolic surface forms in the embodiment a continuation of the spherical surface, and both surfaces serve to gradually and evenly move the material through the various strata of crushing, reducing and triturating effects, until the material is discharged through the outlet 48. A parabolic curve has been shown, but an elliptical or other transitory curve may be used. It will be particularly noted that in the embodi ment shown in-Fig. 1, the material entering into the reducing zones enters gradually; and while entering 1s -SlllOJQClIQd to the crushing effects, by reason of the particular when the material reaches the position indi- .Fig. 2.

cated by 7) and c, it is also subjected to gravity asindicated by the arrows .0 and 0 but at the same time it has a tendency to be moved in the direction of the arrows 7/ and c and the resultant force brings about a triturating action. By the employment of my invention, a very eliicient mode of oper ation and a very etlicient crushing and triturating action is obtained, and this is especially important at the end of the ascending movement of the material as indicated in By the use of my invention at this point, the material is subjected for a longer time to the actions referred to, and a very efficient triturating action is obtained thereby.

One embodiment presents a rotatably mounted shell having hollow trunnions forming inlet and outlet openings with the shell and trunnions havin a continuous unbroken and unobstructed inner surface, and with the shell having at its interior a continuous curved form longitudinally from its greatest diameter to the outlet trunnion, and with the greatest diameter of said shell nearer to the inlet than to the outlet, while another embodiment presents the cooperation of the curved form of the shell with .the crushing bodies. which are freely movable within the shell, and coact with the interior of the shell, in which the radius of the curved part of greatest diameter is smaller than the axial length of the curved part and the curve of that curved part is -a simple curve.

In addition to the material itself which has been described as used in the tumbling barrels, balls or pebbles may be used. depending largely on the character the material to be disintegrated. Ilut as this may or may not be used, and as the material to be crushed acts in a manner like such pebbles or balls, the. words crushing bodies are used in the claims, and for this reason the said words include either the lumps or masses of ore or other material undergoing treatment, or the metal halls, [lint pebbles, ctrz. referred to, or both.

saving power. The mills may be provided with suitable linings, rib linings for instance, and any lining of any kind to prevent wear may be used, these linings not having been shown in the drawings as they are well known. As, by reason of my invention, the higher up the material is in the mill, the greater the sliding or triturating motion of the same becomes, the improvements lend themselves especially to the operation of smaller particles, and by means thereof a short tube mill saving power is obtained. For the larger particles the fall is required which aids in the crushing, and by reason of the small zones, a larger triturating action is obtained.

'lhe interior surface of the shell is unobstructed and is continuously curved from the inlet to the outlet thereof. the inlet and outlet openings being along the same curva ture as that of the shell itself. and the inlet and outlet openings being unobstructed so as to provide an unobstructed passage for the materials The interior of the shell adjacent the inlet opening is curved to C(H 'G- spoud to the rate of settling of the feed at a. certain speed of rotation of the shell. and the interior of the shell adjacent the outlet opening is curved to correspond to the rate of trituration of the material at a certain speed of rotation of the shell. and all these features. combined with a plurality of differently sized freely moving crushing bodies within the shell, bring about an improved shell of special advantages, the plurality of differently and small sized freely moving crushing bodies coacting with the interior curved surfaces of the shell, and adjust themselves according to size and to the curvature of the interior of the. shell, the said crushing bodies extending to the inlet and outlet openings of the shell along the lower part of the shell.

l have described several embodiments of my invention, but it is clear that changes may be, made therein without departing from the spirit of the same, as delined by the appended claims.
