Advantages of AAG Engineering’s loss-in-weight feeder system

loss in weight feeder

At AAG we manufacture loss-in-weight feeder that is engineered and built with a robust design as per the needs of the customers. While manufacturing, special attention is given to maintenance and reliability for long term industrial type operation so as to have lasting relations with our clients.

The loss-in-weight feeder is considered as an all-rounder when it comes to bulk material handling system. They come to rescue for operations when all other feeders fail to provide a solution. That is why they have gained huge popularity and still continue to be the most popular one.

AAG Engineering would be glad to offer its loss-in-weight feeder for your industrial operations with an accuracy of +/-0.25% to 1%. For further details, you can make a contact with us

Mentioned below are the benefits of AAG Engineering’s loss-in-weight feeder system.

Advantages of Loss-in-weight feeder system

  1. Accuracy–In today’s advanced weighing and control technologies, accuracy and reliability is a key component, along with the significant demands placed on weighing and control operations in loss-in-weight feeder system. Our loss-in-weight feeders are highly reliable wit an accuracy of +/-0.25% to 1%.
  2. Range– AAG Engineering offers a complete range of loss-in-weight feeder systems with range of rates that encountered in bulk material handling systems.
  3. Bulk Material Handling– The most beneficial part of loss-in-weight feeder is that it can work efficiently with any kind of feeding device suitable to the process material for e.g., screw, auger, vibrating tray, etc. Even liquid material whose specific gravity varies can be gravimetrically controlled by substituting the hopper/feeder with a holding tank and pump or valve to control.
  4. Material Containment– Taking into considerations specific requirements of industries like food for example where dust or contamination or safety/toxicity is strictly prohibited, loss-in-weight feeder readily lends themselves for such applications.
  5. Tare–Loss-in-weight feeder’s work on the principle of moment-to-moment differences in weight, not just absolute weight. Thus, for the purpose of feed rate control, tare becomes irrelevant.
  6. Weighing– AAG Engineering acknowledges the fact that the demands on the weighing system are substantial for the loss-in-weight feeder. AAG Engineering’s feeder are design with such measurement that requires the highest possible levels of resolution, linearity and stability along with sophisticated filtering and signal processing to extract meaningful weight data from spurious disturbances such as jostling or ambient vibration in the process environment.
  7. Isolation– At AAG Engineering we understand that for accurate weighing loss-in-weight feeder must be effectively isolated from their environment. While installing them we provide with flexible supply and discharge connections for process connections, and appropriate measures needed to assure that in-plant vibration is not transmitted to the feeder through its mounts.
  8. Refill– Periodic hopper replenishment is required. During this intentionally brief phase, whether accomplished manually or by an automated system, weight measurement is unavailable due to the inflow of material, temporarily preventing true gravimetric control. At such time, feeder speed may be automatically reduced to gradually slow feeder speed during refill, accurately compensating for the effect of increasing headload-related material compaction.

With such benefits loss-in-weight feeder are suitable for wide range of operations. For more details contact our sales team at
