Loss in Weight Feeder System

Raman Systems Pvt. Ltd. provides precision-engineered Loss in Weight Feeder Systems in Mumbai, India, designed for accurate and continuous feeding of bulk solids and other process materials. These systems are suitable for applications where precise material dosing, controlled feed rates, and consistent process performance are essential.

Loss in Weight Feeders are widely used across industries for continuous gravimetric feeding of powders, granules, pellets, flakes, and other bulk materials. Depending on the material characteristics and process requirements, the system can be configured with different hopper sizes, feeding mechanisms, load cells, and control systems.

Loss in Weight Feeder System Principle

A Loss in Weight Feeder operates on the principle of continuously measuring the reduction in the weight of a hopper and its contents as material is discharged. The weighing system continuously monitors the weight loss over time and calculates the actual material feed rate.

The feeder controller compares the actual feed rate with the desired setpoint and automatically adjusts the feeder speed to maintain a consistent flow of material.

During operation, the hopper, feeder, and material are continuously monitored through a weighing system, allowing the controller to compensate for changes in material characteristics and maintain accurate feeding throughout the process.

Gravimetric Feeding Principle

Loss in Weight Feeders are a form of gravimetric feeding system, where material flow is controlled based on measured weight rather than relying solely on volumetric measurement. Changes in material bulk density, particle size, moisture content, or feeder filling characteristics can affect volumetric feed rates. A gravimetric system continuously measures the actual weight loss and adjusts the feeder speed accordingly.

For example, in an auger-based feeder, the controller can automatically increase or decrease the auger speed to maintain the required mass flow rate. This provides improved feeding accuracy, consistency, and process control compared with conventional volumetric feeding methods.

Main Components of a Loss in Weight Feeder

• Storage Hopper: Holds the material to be fed.

• Load Cells: Continuously measure the weight of the hopper and material.

• Feeding Device: Auger, screw, vibratory feeder, or another suitable mechanism for controlled material discharge.

• Feeder Motor & Drive: Controls the feeding speed.

• Discharge Chute: Directs the material into the downstream process.

• Loss in Weight Controller: Calculates the material feed rate and controls the feeder according to the required setpoint.

• Control & Communication Interface: Enables integration with PLC, SCADA, or other automation systems.
