Product Description

State-of-the-Art Single Screw Loss-in-Weight Feeders

Thorough Overview
Our loss-in-weight feeders are meticulously engineered for both small and medium feeding requirements, ensuring unmatched precision under optimal conditions. Designed with remarkable flexibility, they adeptly handle bulk solids, liquids, and even challenging, poorly flowing materials. These feeders are integral in a variety of continuous processes, including extruder feeding, where exceptional short-term consistency is paramount. Additionally, they find crucial applications in the food industry and in laboratory settings, thanks to carefully designed storage solutions and tailored feeding systems. Their versatile design spans from compact configurations to sophisticated modular concepts, perfectly fitting the demands of diverse applications.


Innovative Feeding Principle
As material is processed through the feeder, the system’s weight diminishes. The precise control of the loss-in-weight feeder dynamically adjusts the feed rate, ensuring the speed of weight reduction aligns seamlessly with the designated feed rate. These controls are perpetually vigilant, ensuring consistent material flow.
Every element, including the feeder, hopper, and material, is continuously weighed during operation, ensuring unparalleled accuracy.
Gravimetric feeders, though precise, experience slight feed rate variations due to changes in augers' filling capacity and material bulk density. These are expertly corrected by adjusting the auger speed to maintain steady product dispensing.

Comprehensive Loss-in-Weight Feeder Composition
Our loss-in-weight feeders for bulk materials compose of well-engineered storage hoppers and precise feeding mechanisms such as augers, screws, and pumps. They incorporate scales/load cells and sophisticated loss-in-weight controllers for precise regulation.
The Nanjing Pege's feeders have been meticulously tailored for the compound industry, offering flexible installation solutions to fit any space. Diverse feeder and hopper sizes optimize space usage, and vertical container walls enhance the bulk flow. With the innovative off-centre auger arrangement, up to six feeders can be efficiently placed together, allowing customized drive and auger configurations during assembly for enhanced operational efficiency.




1,Wide-Ranging Application Field
Ideal for resin granules, powders, and pellet mixtures.

2,Distinctive Features

• The advanced cantilever sling-type weighing scale bolsters the storage hopper, offering superb vibration reduction and anti-interference capabilities. This effectively isolates non-weight value disturbances, ensuring highly accurate flow measurements.

*Independent Stirring and Feeding ensure optimal flexibility in feeding speeds, adjustable via a variety of speed ratios tailored to material properties, enhancing customer formula modifications.
*Equipped with a servo motor paired with a planetary reducer, the feeding motor delivers precise control, minimal vibration, and a broad flow range—double that of a traditional AC motor.
* The output bearing seat, screw, and sealing device can be effortlessly removed from the hopper, facilitating easy maintenance and cleaning.
* Driven by PTFE gear, the motor and screw assembly provide a crucial buffer if foreign materials cause obstruction, activating an over-torque shutdown alarm to prevent damage to the gearbox or screw.
* The electrical control system is equipped with an Ethernet communication interface to enable seamless remote control.
* Options for PLC, MCU, and industrial computer systems are available to suit diverse customer needs.
* Program source code can be provided to facilitate integration with the client’s upper computer and factory centralized control systems.

FAQs on loss-in-weight feeders

1. How does the loss-in-weight feeder operate?

The gravimetric loss-in-weight feeder is a pivotal tool in controlling and measuring material flow within a system. Designed to handle bulk solids adeptly, it ensures a consistent discharge rate, measured in kg/min or Kg/hour. The weight data serves as a critical feedback mechanism for system control, regulating the feed rate into the instrument. This is achieved through sophisticated weighing systems like platform scales, load-cells, and weigh hoppers. Depending on the process needs, the feeder can function as either a loss-in-weight or gain-in-weight system.
