Loss-in-weight feeders
General Introduction
Loss-in-weight feeders are essential for small to medium feeding ranges, operating with unmatched precision in optimal conditions. These adaptable feeders handle bulk solids, liquids, and unevenly flowing products with ease. Widely used in continuous processes, such as feeding extruders requiring consistent short-term feeding, they also find applications in the food industry and laboratories. Their designs range from compact to modular, tailored to specific needs.
Principle
As the material moves through the feeder, system weight decreases. The loss-in-weight feeder adjusts the feed rate so the weight loss rate aligns with the desired feed rate, ensuring continuous material flow.
Every component and the product within is continuously weighed during operation, including the feeder, hopper, and material.
Gravimetric feeders experience minor feed rate fluctuations due to changes in auger filling capacity and material bulk density. These are corrected by adjusting the auger speed to maintain even product dispensing.
Composition of loss-in-weight feeder
Loss-in-weight feeders for bulk materials include storage hoppers, controlled feeding devices like augers, screws, agitators, and pumps, alongside scales or load cells, and feeder controllers.
Nanjing Pege's loss-in-weight feeders are optimized for the compound industry, offering flexible installation options and various feeder and hopper sizes to fit any space. Vertical container walls maximize space efficiency and enhance bulk material flow. The off-center auger design allows up to six feeders to be positioned next to each other, with customizable drive and auger setups.
