Patented June 9, 1953 UNITED STATES OFFICE PIN 4 Robert R.-'1?eale-, sn'y'uer, N. Y., assigndr' to' Na tiorial Gyiisu'fii -company; B'ufia'lm -Nl Y. Application Aprii 21, 1951.Serial N o; 2221110 This invention relates" to mixers and refers particularly to mixers for preparing slurries of cementitious materials The principles of the mixer of the presentinven'tion may be applied in mixing various materials, but its advantages are particularly evident in preparing slurries for the manufacture of gypsum products, and its constructionjand op"- eration will accordinglybe discussed herein" as applied to the mixing of calcined ypsum or stucco and water to form a slurry of gypsum plaster.
The principles of the present invention are particularly adaptable to mixers of the type known in the art as pin mixers wherein the mixer is' in the form of a relatively fiat cylinder mounted on a vertical axis with the materials moving through the mixer as a combined result of the force of gravity and centrifugal'for'ce and discharging near an edge or peripheral portion of the mixer casing. In such mixers it is customary to introduce the calcined gypsum or stucco and the water at different points located somewhat in the vicinity of the center of the mixer, but conventional construction is such that it isusual to have these two feed entrances disposed separately and each located eccentrically of the center of the mixing chamber and eccentrically of the axis of rotation of the mixing rotor.
, Ordinarily the shaft of the mixing rotor and its supporting bearings require that the separate entrance orifices for gypsum and water be located at points spaced from the central region of the mixer. This design and construction, while generally conventional in this art, results in certain undesirable unevenness and inequal-' ity in mixing results, since the radial path from the point where the gypsum is introduced to the periphery of the mixer is unequal in various directions, the radial path from the point where the water is introduced to the periphery of the mixer in various directions is unequal, and the paths of the two materials are not the same invarious directions.
The mixer of the present invention is so arranged and constructed that it is possibleto introduce both the calcined gypsum or stucco-and the water centrally of the mixer and in such a" way'that their paths and the lengths of their paths in all radial directions to the periphery of the mixer are entirely uniform. Further, this arrangement results in all of the calcined gypsum v or stucco being supplied with water atthe same distance from the axis of the mixer andre'sults 7 Claims.

'Ilhefcovef mem er [3 of tlie mixing chamber is' -pro'vided with a central conduit 20' for intr'o duc'ing I a downward new of" dry calcined gypsum in any desired manner, and its terminal portion extends downwardly centrally of the mixer and centrally of conduit 20 as at 22 in Fig. 2. The terminal portion 22 of water conduit 2| preferably extends down to a point fairly close to the top surface of rotor [5, so that water is forced therefrom uniformly in all radial directions.
A separating sleeve which is likewise coaxial with the conduit 20 and with the axis of rotor I5 is mounted fixedly on a plate 26, which, in turn, is secured to rotor I5 as by means of a plurality of studs 21. A cap 28 extends over the upper end of sleeve 25 and in the illustrated instance is fixed to the downwardly extending portion 22 of the water inlet conduit.
Preferably an upstanding circular series of pins 30 is carried by plate 28 and extends upwardly in the space between sleeve 25 and gypsum conduit 20, the pins serving to keep the incoming calcined gypsum or stucco in a loose and clear flowing condition.
The flow of mixing water and gypsum from the center of the mixer toward the periphery is thus entirely uniform in various directions about the mixer both as to quantity and proportions and the rate of flow is substantially uniform because of these equal values and the uniform centrifugal force on the materials. The material, after passing radially beyond the various intermeshing mixing pins l4 and [8, may be discharged in any desirable manner and at any number of points around the periphery of the mixer. In the present instance, and by way of example only, a discharge spout is designated 3| in Figs. 1 and 2.
In the foregoing specification and the following claims the terms pin mixer and mixing pins are employed and the pins l4 and I8 are shown as being of circular cross-section. However, it is to be understood that the term "pin" is used in a generic sense, and that the pins or bars may be of square or rectangular crosssection or otherwise, that various combinations of pins and bars may be employed, and that the claims are to be construed in that light.
