IV. Initial Setup and Startup
Now that you are familiar with the theory and the modes of operation of the Gravity Separator, it is
time to do the initial startup of the machine.
1. Close the rock trap and the cut out gates on the machine. They will be set up after proper
separation has been achieved. It is suggested to print out the functional operation part of the
manual in order to have a visual reference of the effects of each of the controls.
2. Set the Gravity to the proper initial preset adjustments in Table 2.
3. Start to feed some product on the deck by slowly opening the feeder.
4. Adjust the deck speed to in order to get the product to move up the deck towards the high
side.
5. Turn the two fans nearest the feed in to 100% to help get the product moving down the deck.
6. Once the product is moving towards the discharge end and the deck starts to fill up, bring the
first two fans values back to the preset values in Table 2.
7. When the deck is full, start with the fan at the discharge end of the deck and turn it up until
the product boils, and then turn it down until it just stops boiling. Do this for each fan one at a
time until you reach the feed end of the deck. Repeat the whole process one more time. Once
the fans have been balance twice there should be a good pattern going.
8. The product should be nice and smooth across the deck. The depth of the product at the high
side should be 1-3 time as deep as the light side. If this is not so, increase the side tilt until
the product depth at the high side is 1-3 times that at the low side. If the high side is too
deep in product, decrease the side tilt until the product is the correct depth. Note that the
adjustments need to be made in small increments, and there needs to be sufficient time
between changes that the product depth stops changing, otherwise it will be impossible to
zero in on a good solution for the side tilt.
9. Adjust the deck speed until there is proper disturbance of the product so that the air can
fluidize the product. If this cause separation to go badly, decrease the side tilt to compensate.
Don’t use too much deck speed or the product will remix, causing a bad separation.
10. Adjust the End Raise to that there is not too much product at the feed end to be able to lift
the product into its fluid state. When the end raise is properly adjusted, there should be just
enough product on the deck for the fans to fluidize the product, and there should be either the
same depth of product all the way down the deck, or there might be all the way down to 1/3
of the product on the deck at the discharge end. This will all depend on the product used.
11. Increase the feed rate, compensating with the End Raise to keep the product flowing, until the
gravity has reached the maximum amount of capacity it can separate well. Don’t put too
much product on the deck so that the separation suffers.
12. Finally open the rock trap and cut out gates. The cut out gates will allow more capacity on the
deck. Just be sure not to open them too much. Just make small changes until the product
capacity and separation are both balanced. Start with the cut out gate at the discharge end.
