CENTRIFUGAL cRUsl-ilNc-MILL.
SPECIFICATION forming part of Letters Patent No. 569,238, dated October 13, 1896.
Application tiled May 6, 1896. Serial No. 590,475. (No model.) Patented in Germany February 6, 1891, No. 58,680; in Austa-Hungary April 29, 1892,110. 53,929 and No. 90,583, and in England January 26, 1895, No. 1,892.
To @ZZ whom t may concern:
Be it known that 1, RICHARD SAUEEBREY, a citizen of the German Empire, residing at Stassfurt, in the Kingdom of Prussia, in said Empire, have invented certain new and useful Improvements in Centrifugal Crushing- Mills, (for which I have obtained patents in Germany, dated February G, 1891, No. 58,630; in Austria-Hungary, dated April 29, 1892, No. 53,929 and No. 90,583, and in England, dated January 2G, 1895, No. 1,8925) and I do hereby 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.
In the accompanying drawin gs,Figure 1 represents a side elevation, one-half in vertical central section, of a crushing-mill embodying my invention. Fig. 2 represents a plan view of the same, all parts above the conoidal body an d also one-half of the latter being removed and Fig. 3 represents a detail sectional view, on an enlarged scale, of a part of the conoidal grinding devices.
The centrifugal crushing-mill of this present invention is remarkable for the concentration of the effective or working parts upon the smallest possible compass. The material to be reduced is not subjected to a grinding or triturating action, but is turned into flour or dust only by the effect of blows caused by centrifugal force. There are quite a number of similar mills known, but this present machine shows peculiarities of its own which exert important and favorable influences upon the process of reducing. In the rst place the step-like arrangement of the rotating body or cone, and correspondingly the stationarybell or mantle, offers the advantage that as the material fed is being beaten smaller and smaller it is being subjected to the increasing centrifugal force. The turn-table plates I II III IV being provided with ribs, a ventilating effect is being attained, and by fitting elevated rings around the periphery of these plates the eifect of the blows is still increased.
As appears from the accompanying drawings, the principal improvement in this machine consists in the arrangement of a rotating body h of step-like circular plates I II III IV, dac., provided with raised edges d and ribs c. Y The ribs c, when body b is rotating, cause a strong current of air, since they act like the wings of a fan. This draft carries the material fed through adjustable hopper a downward in the direction of arrow C, Fig. 3. During its passage it is thrown back upon the rotating plates from or by the corresponding parts of the mantle, where by the centrifugal force it is driven again toward edge d. Here it overcomes the friction between the material to be ground and the plates, and is now thrown onward in the direction of arrow A. The result of the two components A and C is the actual direction of arrow B. Thus the action goes on until the material nally gets to ring f, attached to h, and consequently rotating with h, whence, with the assistance of the existing current of air and a striker, (not shown in the drawings) it is passed out of the machine at outlet g, Fig. 2. Thus the material with this machine is not ground in the usual way nor knocked about by pins, but by its living force, m's cica, it is being thrown against the mantle and thus broken up. The current of air produced by the rotation of the body?) serves at the same time for cooling the material, which otherwise doubtless would get hot in consequence of the transformation of @is mba into heat caused by the sudden destruction of the former.
The continually-decreasing dead-Weight of the individual particles of the material is being balanced by the lower steps increasing in size and the consequently greater centrifugal force, so that the momentum of the m's moet approximately remains the same. The ribs c will also help to reduce the material, since during its descent it will continually receive blows as it knocks against these ribs.
The main purpose of ribs c is the creation of a current of air, while the reduction by the catching and the knocking about and the collisions of the material by and with these ribs is only a secondary consideration.
The ring-like edges D hold the material back until nally the centrifugal force overcomes the resistance, when the material is thrown olf with so much greater force. Besides this edge gives to the material a pecu- IOO liar direction, so that it cannot be carried off said troughs having within them ribs c for immediately by the strong current of air. creating a current of air substantially as set Having' now particularly described and asforth. l certained the nature of the said invention and In testimony whereof I have hereunto 15 5 in what manner the same is to be performed, l signed my name in the presence of two sub- I declare that what I claim is* scrbng Witnesses.
