This procedure does not eliminate segregation, but spreads it out and minimizes the effect. For large trucks, the procedure doesn't require going all the way to the back of the truck, but balancing the drop, and creating an overlap in loading sequence from front to rear. Pugmilled batches dropped in small increments, similar in pattern to silos, have similar segregation patterns. Back To Contents Back To Top Clam type bin gates prevent problems Several gate models are in use on surge and silo bins. They vary from rectangular to round, and can include plates and baffles.
Gates are a common spot at which segregation occurs.
Most agency specs require clam or other type of gate openings that will not cause segregation. They open both transversely or longitudinally to the truckbed. Type of gate opening may be secondary to segregation in the configuration of the silo. To place material in the storage bin without segregation, the speed of these systems must be balanced with output tonnage. Small amounts of material on a fast belt will segregate when it is placed in the surge, and coarser material will be slung to the far side of the drop chute or other device in place to funnel material into the batch hopper.
