Duplex jig operation

  1. The gravel from the classiffier is fed into the continuous jig, either manually, or mechanically. The classiffier if mounted on a trailer can discharge straight into the cont jig.

  2. The jig works with water, and pulsates continuously, there are two bellows on the machine, the up and down movement-on the 1 side it pushes the gravel up, while on the other side it pulls down the material.

    There is a continuous flow of water being pumped into the machine, as well as a flow of water flowing with the gravel, which helps the gravel to move forward and eventually out of the machine.

  3. The top of the machine is covered with a screen to keep any hands out of the concentrate.

  4. The machine is fitted with a winch to empty the concentrate twice daily, depending on the production.

  5. The machine is also fitted with two stainless steel security containers which when removed lock automatically, and can only be opened by the person with the key(security containers).

  6. This operation reduces the amount of gravel coming off the classiffier to 1% concentrate.

Benefits of continuous jig

  1. Fuel saving – no transport of gravel, no excess travelling to transport gravel, thus fuel saving. Only 1% of concentrate to be transported.

  2. Labour saving – labour with jigging on land – 1% time required, labour of transport.

  3. Security – only concentrate needs to be jigged or sorted, normal jigging can be substituted with hand sorting – less people involved.

  4. Gravel can be inspected as it goes through jig, thus you can see when diamonds are coming up.

  5. Jig only needs to be emptied twice a day.
