Feeding/Blending: Dual Auger Powers New Feeder

Unlike other volumetric feeders where a single auger is typically located at the bottom of a trough, a new line features a double concentric auger.

Acrison’s Model 140 Series Feeders utilize a conditioning auger, or intromitter, as well as a metering auger to move dry solids. In this design, Acrison says the conditioning auger is mounted around the smaller metering auger. The augers are independently driven at dissimilar speeds in a fixed proportion to each other by a single variable-speed gear motor. This design reportedly results in a highly accurate, dependable and versatile metering of a wide range of dry solid materials.

Acrison says that in typical volumetric feeders where a single auger is located at the bottom of a V-shaped trough materials often bridge despite vibration or agitation. In the Model 140 Series, rotation of the metering mechanism’s slower speed intromitter is said to produce gentle unidirectional movement of material within the feed chamber. Acrison says this conditions the material to a uniform state while simultaneously filling the metering auger from a full 360 degrees. Available in three different models ranging up 3400-ft3/hr in throughput, the Model 140 Series Feeders feature all-steel, heavy-duty construction.

    These are the screw trough, agitator, and the screw itself. It’s crucial to understand the different types and the advantages/disadvantages of each.

  • Materials Handling: New Equipment Emphasizes Efficiency & Value

    Visitors to the recent NPE 2009 show in Chicago were looking for materials handling equipment that could do more than dry, blend, or convey resins. It had to do those things while saving energy, providing faster and easier maintenance, speeding product changeovers, reducing labor cost, minimizing waste, and providing better value for money. The new products cited below addressed those needs and more.

  • Coloring on the Machine: You Can Do It Right

    Coloring at the machine can offer significant cost benefits, including lower material inventory costs and improved process flexibility when compared with the cost of buying precolored resin or installing a large-capacity central blender to premix resin and color concentrate.
