Loss-in-weight feeders are ideal dosing systems for a variety of applications from bulk, dry materials to liquids and even poorly flowing materials. Loss-in-weight feeders can be used in many industries from food or chemical production to high-temperature or ATEX environments.
The picture below illustrates the PFISTER® weighing and dosing principle. Operating principle. Material is extracted out of the pre-hopper and is transported in the rotor chambers from the inlet (1) to the outlet (2). The rotor body is mounted on bearings that form a weighing axis (A-A). ... This means the rotor weigh-feeder measures the ...
Working Principle: A weighing feeder operates on the principle of gravimetric feeding, which means that it measures the weight of the material being fed to determine its flow …
The working principle of a weigh belt feeder is simple. Weigh belt feeders operate by continuously weighing a moving bed of material on its short conveyor, and controlling belt speed to result in the desired flow rate at discharge. The main component of the weigh belt feeder is the drive roller which is used to rotate the pulley.
Continuous Loss In Weight Feeding… How Does It Work. A continuous Loss In Weight system includes a supply hopper or tank, a metering feeder or pump, a supporting scale system, and a microprocessor …

Operating Principle of a Weigh Feeder - Free download as PDF File (.pdf), Text File (.txt) or read online for free. A weigh feeder operates by allowing material from a hopper to flow onto a moving belt over a weigh bridge. The material on the belt exerts a load on the weigh bridge, which is measured along with the belt speed to calculate the flow rate and …
2. Weight Balancing and Isolation from Vibration Influences. Because weighing is the basis for feeding accuracy, the feeder as well as the weighing unit must be isolated from the influences of external forces, friction, vibrations or shock. This is accomplished by installing flexible connections e.g. at the feeder inlet and outlet.
The simplest form of bulk material transportation is to convey them over a moving belt and it is necessary to weigh a moving bulk material accurately to control the process as per requirement. Weigh feeder is a closed-loop control system, which controls the flow of material very accurately …
