Increasing Capacity
Once the separation quality required has been obtained, begin increasing capacity. Open the feed gate slightly. This increases the feed so the bed depth will increase.
Observe the charge in the material on the deck. Then increase the slope to compensate for the increased feed. Continue increasing the feed and slope until the maximum feed has been reached, where the machine can still maintain the required separation. The AIR may have to be increased slightly to compensate for the thicker bed of material. It is possible to increase capacity even more by opening the gates along the high side of the deck.
Begin by opening the gate closest to the discharge end of the machine. Turn the gate counterclock-wise and open the cutout gate until a small amount of product begins to discharge into the blender trough. As you allow product to discharge into the blender you can increase the feed by a corresponding amount.
Normally as you begin releasing more and more product from the deck into the blender you will note a change in the air flow pattern on the deck. After making adjustments to the cutout gates go through the air balancing procedure periodically. The number of gates that may be opened should be determined by the difficulty of separation and the end results required. The easier the separation, the more gates can be opened and the higher capacity can be obtained.
Always remember that capacity and quality off set one another. Therefore, if the separation quality does not meet standards, lower the capacity of the machine. Conversely, if the end product is better than it needs to be, increase your operating capacity.
