| 74 | Separation system for a potato harvesting machine or a preparation machine | US14421180 | 2013-08-13 | US09357694B2 | 2016-06-07 | Klemens Kalverkamp; Franz-Josef Dettmer; Christian Döhmann |
| The invention relates to a separation system for a potato harvesting machine or a preparation machine for separating potatoes, or similar crops, from a mixture of clods, stones, and similar solid bodies. A conveying assembly is thereby utilized to feed the essentially compact mixture as a delivery flow, from where the mixture displaced into the area of at least one drop stage, and thereby influenced by way of a conveying means in the form of an air stream, can be separated. Thereafter, at least the harvested material and the solid bodies, respectively, can be moved on as individual separated goods, and can be moved out of the separation system. The system according to the invention is characterized in that subsequently to the drop stage bringing about a loosening of the mixture, at least one retaining element located opposite the falling separated goods and interacting with the at least one air stream is provided. It is thus achieved in a surprisingly simple way that from there, at least the harvested material and the solid bodies, respectively, can be moved on separately in an essentially opposite conveying direction as sorted individual lots. | ||||||

| A system for density-based particle separation includes a loading bin, a separating feeder, a mesh conveyor belt, a compressor for the mesh conveyor belt, transporting nozzles integrated with the separation bins and located over the mesh conveyor belt, discharge nozzles positioned under the mesh conveyor belt in the same plane with transporting nozzles and adjusted for separation of the primary material into particle products of specific density and an aspiration systems (cyclones), as well as fans for generation of ascending sucking air flows in the transporting nozzles and discharge flows in the discharge nozzles. | ||||||
| 76 | Procedure and apparatus for separating heavy particles of material from lighter ones | US715452 | 1996-09-18 | US5964355A | 1999-10-12 | Pentti Raura |
| Procedure for separating heavy particles of material from lighter particles, e.g. for separating impurities from powdery or fragmental material, such as fibers or chips, in which procedure the material (2) to be treated is supplied onto a carrier surface (1) pervious to gas and gas impacts (P) are applied to the material through the carrier surface (1), causing the heavier particles to move closer to the carrier surface (1). The carrier surface (1) is mainly moved in one direction of movement to move the heavy particles (R) and the lighter particles (K) are passed, mainly by the agency of the inclination of the carrier surface (1) and/or the gas flow, in a direction substantially differing from the principal direction of movement of the carrier surface (1). The invention also relates to an apparatus implementing the procedure. | ||||||
| 77 | Apparatus for dry placer mining | US872963 | 1992-04-23 | US5375721A | 1994-12-27 | Gordon LaVigne |
| A dry placer mining machine and a belt assembly for use therewith. The machine concentrates metallic constituents from a gravel mix by fluidizing the mix with air which passes upwardly through the belt assembly, and moving the fluidized mix over the belt and applying an electrostatic charge thereto. The belt assembly is made up of a composite fabric belt member and a plurality of riffle members which extend transversely across this. The composite fabric belt member is constructed of non-conductive materials so as to minimize dissipation of the electrostatic charge, and this is made up of a finely woven cloth top layer, a reticulated foam middle layer, and a coarse mesh lower layer. The riffle members, in turn, are provided with insulation for preventing the electrostatic charge from being conducted away from the fabric belt member. The belt assembly is driven over the open upper end of a plenum chamber, and air pressure is supplied to this through a blower and ducting. The internal surfaces of these components are coated with an insulating material which enhances the build-up of electrostatic charge on the airflow. | ||||||

| <PICT:0916482/III/1> In a continuous method for contacting finely divided particles, e.g. starch, with a gas, e.g. anhydrous hydrogen chloride, a stream of the particles is conveyed through a confined contact space containing the gas and having an inlet and outlet arranged so that they are continuously filled with the particles to prevent escape of the gas. Particles are fed from a belt 41 (Fig. 1) to a conveyer 10 having a floor 11 and sides 12, which is mounted on a carrier 13 vibrated by an eccentric 19, carrier 13 being supported on flexible struts 28. The vibrations cause the particles M to flow from right to left, passing through a chamber 32 filled with gas supplied by diffuser 39. The conveyer floor 11 has V-shaped transverse depressions 35 and 351 below end walls 34 and 341 forming an inlet 36 and an outlet 37. The particles flow down into and up out of depressions 35 and 351 filling inlet 36 and outlet 37. Dust formation at openings 36 and 37 is eliminated by flanges 38 and 381. The floor 11 has transverse protuberances 27 which mix the stream of particles to ensure uniform contact with the gas. Carrier 13 is in the form of a channel and conducts material discharged from conveyer 10.ALSO:In a continuous method for contacting finely divided particles of starch with anhydrous hydrogen chloride, a stream of the particles is conveyed through a confined contact space containing the gas and having an inlet and outlet <PICT:0916482/IV(a)/1> arranged so that they are continuously filled with the particles to prevent escape of the gas.
