| 20090084711 | APPARATUS FOR SCREENING FIBROUS SUSPENSIONS - An apparatus for screening a fibrous suspension including: a housing, conduits therein at least for fiber suspension being fed, reject and accept, and a rotor and a cylindrical screen drum installed in the housing, at least one of which is rotatable, whereby a surface of the rotor is provided with rotor elements in proximity to the surface of the screen drum, whereby each rotor element includes a front surface facing a flow of the fiber suspension, an upper surface and a trailing surface sloping from the upper surface towards the surface of the rotor, wherein the trailing surface of the rotor element is curved and sidewalls of the trailing surface converge at a back point of the rotor element. | 04-02-2009 |
| 20110198268 | HYBRID ROTARY SCREEN SEPARATOR - The present invention may be embodied as a rotary screen separator for processing feed material. A separator member defines a longitudinal axis, an input port, an output port, a fine perforation region, and a coarse perforation region. A collector structure defines a fine material output and a coarse material output. A support structure supports the separator member and the collector structure. A drive system rotates the separator member relative to the support structure. Operation of the drive system displaces feed material through the fine perforation region and the coarse perforation region. A first portion of the feed material flows through the separator member to the fine material output in the fine perforation region. A second portion of the feed material flows through the separator member to the coarse material output in the coarse perforation region. A third portion of the feed material flows through the output port. | 08-18-2011 |

| 20130001138 | Particle Classifier Apparatus - A particle classifier apparatus used to mine for gold and other precious particles. The present invention is meant to replace the sluice box or any inefficient means for gold mining. The present invention is used with and without a stream of flowing water. The present invention comprises a PVC channel, a main trough and a plurality of small troughs. The PVC channel comprises a slit with a narrow end and a wide end. The present invention is designed for the stream of flowing water to flow from the narrow end to the wide end. The water flow pushes the particles through the slit and into the plurality of troughs located beneath the slit. The smallest particles fall into the narrow end whereas the big particles fall into the wide end. The plurality of small troughs are removed from the main trough so the captured particles may be panned for gold. | 01-03-2013 |
