  • the rubber mountings are custom made using a specific prescribed rubber mix. The flywheels 56 and rubber mounting work together, removing one or the other will render the vibrating screen useless.
  • gravel falling onto the screens 58 is sprayed with high pressure sprayers (not shown) and then propagates along the length of the vibrating screen 50 towards the outlet end 54 under the influence of the vibrations caused by the set of imbalanced flywheels 56.
  • Predetermined sized mineral containing ore falls through the screen apertures and is passed through chutes 60 into the aqua concentrator 70. Larger sized gravel propagates to be discarded at the outlet end 54.
  • the aqua concentrator 70 has two chambers 72, 74, each of which is provided with a screen 72.1 , 74.1 onto which the mineral containing ore with a specific gravity of more than 2 will settle. Smaller particles with a specific gravity of more than 2 would settle through the screens 72.1 , 74.1 downwards to the cyclones 1 10. Water is pumped from the bottom of each of the chambers 72, 74 in a pulsating fashion upwards through the screens 72.1 , 74.1 and out at the exit points 72.2, 74.2. Particles with a specific gravity of less than 2 will float off towards the exit points 72.2 and 74.2. The pulsating water flow in the chambers 72, 74 generate bubbles and provide a separation action, which separates particles based on their specific gravity.
  • the cyclone 1 10 collects all particles that passed through the screens 72.1 , 72.4 and again separates small particles with a specific gravity of more than 2 from small particles with a specific gravity of less than 2.
  • the cyclone 1 10 operates by causing a vortex that separates the particles. Water flows into the cyclone 1 10 at 1 12 and exists the cyclone at 1 14 together with particles with a specific gravity of less than 2. Particles with a specific gravity of more than 2 settles into the cyclone and exits at 1 16, where it is collected into a container (not shown).
  • Connected to the aqua concentrator 70 is an auger 90. Water flowing from the aqua concentrator is passed into the auger 90.
  • the auger 90 has three functions namely:
  • Internal valves (not shown) within the aqua concentrator allows water to flow between the auger and aqua concentrator without affecting the concentrating capabilities of the aqua concentrator. Very fine material with a specific gravity of above 2 that fall through the aqua concentrator internal screens will be directed towards the cyclones, away from the auger that will receive all light material of all sizes with a specific gravity below 2.
  • the cyclones need the water pressure generated by the aqua concentrator and auger to function, as this pressure supply the smaller material from the aqua concentrators that need to be concentrated and also the water pressure needed to create the vortex within the cyclones.
  • the auger recycles the water within the aqua concentrator. If not for this function, the processing plant would need 10 times more water feed per hour to function properly.
  • the processing plant only uses 6000 L of new water per hour.
  • gravel is fed into the gravel receptacle 38 while it is rotating, the gravel scoop 40 takes gravel, which is then fed into the scrubber tubular feed 32.
  • the gravel progresses upwardly under influence of the helical inner blade 34 and is further broken down by the radially extending fingers 44 and is disposed at the outlet end 42 from where it falls onto the vibrating screen 50.
  • the gravel is washed by high pressure sprays (not shown) and progresses over the screens 58 towards the outlet end 54 where large gravel is disposed.
  • Mineral containing ore passes through the screen 58 apertures and via chutes 60 into the aqua concentrator 70.
  • Excess ore with a specific gravity lower than 2 is disposed from the aqua concentrator into the auger 90 from where it is disposed.
  • the cyclone 1 10 separates particles with a specific gravity of 2 or higher, which is disposed at the outlet 1 16 from particles with a specific gravity of lower than 2 which is disposed at the outlet 1 14.
  • the inventor believes that the invention, as described and illustrated provides a new mobile processing plant, which will be of particular use in the small mining industry.
  • the combination of the aqua concentrator, auger and cyclones is not known in this configuration.
  • the aqua concentrator's design is unique as it do not need any separation medium to be added in the concentration process, only uses water.
  • the cyclone is unique as it receives its water supply directly from the aqua concentrator.
  • the auger design is unique in the way it works in tandem with the aqua concentrator and cyclones.
  • the angle of the scrubber and its internal processes are also unique.
