The mixer is using a plug flow principle but should however allow a certain degree of back mix in order to cope with dosing inacurracies of the loss in weight feeders (LIWF). There are indeed 2 mixing effects that need to be combined in order to reach a proper degree of homogeneity : radial mixing and axial mixing.

Model 400 Series Weight–Loss Weigh Feeders Overview. Acrison's various Model 400 Series of Weigh Feeders operate on a Weight-Loss-Differential (or loss-in-weight feeding) basis; they are designed with an integral Acrison dry solids feeder, or a positive displacement liquid pump, as the metering mechanism of these precision all-digital weigh feeders, precisely controlled by an .

Figure 1 : Dosing principle for a Gain in Weight system. Loss-in-Weight dosing (LIW) Contrary to GIW dosing, the hopper on load cells driving the dosing is located above the dosing instrument. It means that, when the dosing instrument runs and deliver the product, the weight of the hopper from which the product is taken is decreasing, it is ...

The STOCK® gravimetric feeder weighs material on a belt between two fixed points (span) precisely located in the feeder body. A roller, located midway in the span and supported at each end by precision load cells, supports half the weight on the span. The load cells generate an electrical signal directly proportional to the weight supported.

Principle: When the material is fed through the feeder, the weight of the system decreases. Controlling the loss-in-weight feeder changes the feed rate and as a result the speed of weight loss matches the desired feed rate. Loss-in-weight feeder controls continuously check whether the material is flowing.

Gravimetric (loss of weight) feeding A gravimetric (loss of weight) feeder is implemented by utilising a weighing system configured to weigh the whole hopper/feeder system, together with its contents (the prod-uct to be fed). The basic loss of weight principle is to dis-pense the product at a constant loss of weight per unit time

vibration and shock. For example, at a given feed rate, a smaller diameter feeder screw will rotate faster than a larger diameter one, minimizing the effect of discharge stream pulsing. Shift-ing to a twin screw also minimizes pulsing. A high-resolution weighing system will more finely discern weight changes, mak-

Loss-in-Weight Overview. Principle In loss-in-weight feeding, the entire feeder, hopper and material are continuously weighed. As the feeder discharges material, the rate of decline in system weight is computed, and feeder speed is adjusted to maintain the desired (set) rate.

A gravimetric loss-in-weight feeder simply weighs material to achieve a required feed rate or batch size. Depending on the feeder type, a loss-in-weight feeder can operate in continuous or batch mode. The continuous feeder controls the weight (not volume) of material fed over time -- typically in lb or kg of material per hour.
Get PriceThe Vibra Screw Continuous Loss In Weight Feeder provides unparalleled versatility in handling a broad range of feeding requirements. Feed rate from 20 pounds to 24,000 pounds per hour can be accomplished with accuracies of plus or minus 1/4-1% on a minute-to-minute basis at 2 sigma.

Because the loss-in-weight (LIW) feeder typically uses a volumetric screw feeder to meter material, many of the volumetric feeder problems and solutions already covered also apply to the LIW feeder. But since the LIW feeder's operation is based on the weight-loss rate per unit time rather than the screw speed, the controller automatically ...

A Batch Weighing System is similar in design to a continuous Loss-In-Weight Feeder. Batch applications do not, however, require that material be continuously fed with high-feed accuracy. They do require that the desired weight of material at the end of the feed cycle is accurate. Control of batch size and feed time is provided through a unique ...
