摘要： An apparatus comprises a hopper housing, a first auger, a second auger, a dividing panel, and a motor. The hopper housing holds a bulk material, with the hopper housing including a first end at which the bulk material is added to the hopper housing and a second end comprising a discharge opening at which the bulk material exits the hopper housing. The first auger is disposed proximate to the discharge opening. The second auger is disposed between the first end of the hopper housing and the first auger. The dividing panel is disposed between the first auger and the second auger and the dividing panel is coupled to the hopper housing at the first side thereof and forming a panel opening between the hopper housing and the second side thereof. The motor rotates the first auger and the second auger to move the bulk material into the discharge opening.

摘要： The disclosure relates to a metering apparatus for free-flowing material and to a method for operating such a metering apparatus. The metering apparatus has a metering duct having a closed cross section and further has a rotary drive (M). The metering duct is wound in the form of a screw with a vertical longitudinal axis. The free-flowing material is fed to the metering duct. The metering duct is set via the rotary drive (M) in an oscillating rotary motion about its longitudinal axis with individual rotary strokes, wherein, with each rotary stroke, a partial quantity of the free-flowing material falls out of a lower discharge opening of the metering duct.

摘要： A material dispensing pump includes a drip prevention system and method so as to avoid undesired dripping of the dispensed fluid. In one example, the fluid path is sealed. Positive pressure is applied to the fluid during a dispensing operation to present the fluid to the auger-style pump at a desired rate. Between dispensing operations, or when dispensing is completed, the fluid is placed in suspension, for example by applying a negative pressure, thereby preventing the fluid from being inadvertently released at the dispense tip. In addition, following a dispensing operation, the pump dispensing controller can be programmed to reverse the rotation of the feed screw, in order to draw the material in a reverse direction and to further suspend the fluid.
