Loss-In-Weight Feeder The continuous loss-in-weight principle involves weighing the entire feeding system (hopper, feeder, and bulk material) by means of a static-type scale system, and controlling the discharge feed rate of the bulk material by means of a variable speed motor. Material is discharged from the system,

conveying, weighing and control functions. In operation, a weigh idler senses the material weight while the speed sensor measures the speed of the feeder belt. The instrumentation multiplies the weight and speed in producing a "true rate" signal which is compared to a set-point or "demand value". Any deviation from the

The filter should be programmed to recognize also strong disturbances and take action in consequence. If the feeder is not anymore able to calculate accurately a loss of weight, it will turn automatically to volumetric feeding, fixing the speed of the dosing tool.Such measure is an approximation and can only be acceptable if the feeder stays in volumetric mode for a short time.

1. Separate plant vibration noise from true weight loss. A LIW feeder's operation depends on accurate measurement of the material weight in the hopper, so the feeder and weight-sensing device must be isolated from external forces and vibration. Position the feeder so that no external forces or friction can influence weighing. Isolate

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.
