Product Description

Single Screw Loss-in-weight Feeders

General Introduction
Our Loss-in-weight Feeders offer unparalleled precision for a range of feeding requirements, from small to medium scales. Crafted to deliver exceptional accuracy under ideal ambient conditions, these feeders seamlessly manage bulk solids, liquids, and even challenging products. Widely employed in continuous processes, they ensure impeccable feeding consistency for extruders and are indispensable in the food industry and laboratories. With designs that range from compact constructions to modular concepts, they adapt effortlessly to diverse applications.


Principle
The Loss-in-weight Feeder operates on a sophisticated principle: as material is dispensed, the system's weight decreases. The feeder's control system dynamically adjusts the feed rate, ensuring the speed of weight loss aligns perfectly with the desired feed rate. Constant monitoring guarantees unimpeded material flow.
Throughout operation, every component of the system—including the feeder, hopper, and material—is continuously weighed, ensuring unmatched precision and reliability.
Gravimetric feeders exhibit slight feed rate fluctuations due to changes in auger filling capacity and material bulk density. These are expertly balanced by adjusting the auger speed, ensuring a smooth and uniform product dispensing experience.

Composition of loss-in-weight feeder
Composed of storage hoppers, precise feeding mechanisms like augers and screws, and advanced scales or load cells, the loss-in-weight feeder system is equipped with state-of-the-art controllers to maintain optimal performance and accuracy.
Nanjing Pege's cutting-edge loss-in-weight feeders are tailored for the compound industry. With flexible installation options, a variety of feeder and hopper sizes, and efficient vertical container walls, they maximize every millimeter for optimal bulk flow. The unique off-centre auger arrangement allows up to six feeders to be positioned side by side, while the drive and auger setup remain customizable during assembly.
