A loss-in-weight feeder is a gravimetric feeder that directly measures the material's weight to achieve and maintain a predetermined feed rate measured in units of weight per time. The following section ( The Gravimetric Feeding Triangle ) introduces the three main challenges faced by any gravimetric feeder: material handling, weighing and control.
Weigh Feeder. The load cell measures the weight of a fixed-length belt section, yielding a figure of material weight per linear distance on the belt. A tachometer (speed sensor) measures the speed of the belt. The product of these two variables is the mass flow rate of solid material "through" the weigh feeder: A small weigh feeder (about ...

Please keep in mind that a loss in weight feeder is selected for highly accurate controlled rate feeding, not storing. Storing should be separate. 5. Venting and Dust Collection During Refill: In the Schematic 5 below, 3 types of feeder venting are shown. Schematic 2 – Venting a Loss-in-Weight Feeder Stepped Bellows Filter Bag
The Smart Weigh Belt Feeder SWB is used for continuous controlled gravimetric feeding of bulk materials. The most typical application is for feeding/weighing into a continuous process. By utilizing different control software, the SWB can also be used to feed material into a batch system.
Weight-Loss weigh feeders (gravimetric feeders) operate strictly on the basis of the loss of a specific amount of weight (product) in a specific amount of time. There are no other factors that enter the equation.
Weigh Feeder models cater for bulk materials feed rates from 1kg to 5,000 tph and deliver weighing accuracy 0.5% and better. Solids Feeders – Vibratory Compact …

Z Coriolis scales, also known as Coriolis flow rate scales or mass flow rate measuring devices, measure the weight of a mass flow using the Coriolis force. They are most commonly used to measure bulk materials such as dusts, powder or gravel. Coriolis scales are also good for measuring granulates or cereals.
