Abstract: A planetary mill adapted for the continuous grinding of granulated material into fine powder is disclosed. A grinding chamber is provided that is continuously orbited in a planetary motion. As the tube undergoes its planetary motion it is caused to undergo a rotation about its own axis at the same rate and in an opposite sense to the planetary rotation. As a result the grinding chamber has no net rotation with respect to an external observer and can be connected to any number of external connections without the use of rotating seals provided the drive for the planetary rotation is external to the locus of points encompassed by the path of the connections as the system rotates. The ratio of the orbit radius of the planetary motion is 2.15 times that of the cylindrical tube so as to cause a cascade angle of about 45 degrees of mill mix and media in the orbiting tube which angle is independent of the rotation rate of the mill at reasonable speeds.

Abstract: A centrifugal mill adapted for the continuous grinding of granulated material into fine powder is disclosed. At least one pair of grinding chambers is provided. The grinding chambers are rotated about their own axes one revolution in the opposite direction to the orbiting direction for each orbit and the orbiting radius is about 1.2 to about 4.0 times the grinding chamber radius. Under these conditions the grinding chambers do not rotate relative to the machine base so that communication with the grinding chamber and any surrounding jacket may be made through flexible hoses or tubes thereby avoiding the need for rotating seals. If desired, the grinding chamber may be subjected to atmospheres of controlled temperature, pressure and composition. As the grinding chamber atmosphere is isolated from the ambient atmosphere, contamination is avoided.

Abstract: A rotary apparatus, such as an ore grinding mill, has a wrap-around drive motor secured thereto for rotating the apparatus about a central axis. The drive motor includes a rotor attached to and surrounding the apparatus and a stator surrounding and spaced from the rotor and coupled to the apparatus by anti-friction or journal bearings.

Abstract: In a process and plant for producing cool sintered particulate agglomerated solids of ore, the solids are moved in a continuous stream through a heat-treating zone to form a layer of the agglomerated solids and hot particles thereof are obtained from the layer.

Cooling air is blown into the cooler to flow countercurrently to the continuous stream of hot particles in the cooling path to subject the hot particles to forced countercurrent cooling whereby the cooling air is heated by contact with the hot particles and the entire heated cooling air is delivered into the heat-treating zone.
