Product Description

Single Screw Loss-in-weight Feeders

General Introduction
Loss-in-weight feeders are the epitome of precision and flexibility, engineered for small to medium feeding ranges. These feeders excel under optimal conditions, accommodating bulk solids, liquids, and even challenging, poorly flowing materials. Their versatility shines in continuous processes, particularly for feeding extruders where consistent short-term feeding is paramount. Additionally, they find vital roles in the food industry and laboratories, thanks to bespoke storage containers and tailored feeding devices. The design ethos ranges from compact units to modular systems, ensuring adaptability across diverse applications.


Principle
The operational magic of loss-in-weight feeders lies in their ability to dynamically adjust the feed rate as the material weight decreases. This ensures the weight loss rate aligns perfectly with the desired feed rate. The system continuously monitors material flow, providing unmatched consistency.
Throughout operation, every component including the feeder, hopper, and material is weighed, ensuring continuous precision.
Gravimetric feeders, like all precise machinery, experience slight feed rate fluctuations due to variations in auger filling capacity and material bulk density. These are expertly mitigated by adjusting auger speed, maintaining an even and reliable product flow.

Composition of loss-in-weight feeder
These advanced feeders for bulk materials incorporate storage hoppers, precision-controlled feeding devices—be they augers, screws, agitators, pumps—as well as integrated scales or load cells, paired with sophisticated loss-in-weight controllers. This combination ensures optimal performance and accuracy.
Nanjing Pege's loss-in-weight feeders are tailored for the compound industry, offering flexible installation options, a range of feeder and hopper sizes, and vertical container walls that maximize space efficiency. The ingenious off-centre auger arrangement allows for close proximity of up to six feeders, while the drive and auger setup remains customizable during assembly.




1,Application field
From resin granules to powder and pellet blends, these feeders are ideal for a wide array of applications.

2,Features

• With a cantilever sling-type weighing scale, the system is built to withstand vibration and anti-level interference, ensuring non-weight value interference is minimized, allowing for accurate flow measurement.

*Stirring and feeding mechanisms are independently driven, offering adaptable feeding speeds. Choose from various speed ratios tailored to material characteristics, enhancing customer formula flexibility.
*For ultimate precision, the feeding motor employs a servo motor coupled with a planetary reducer. This setup provides light weight, minimized vibrations, constant low-speed torque, and an extensive flow range that outperforms traditional AC motors.
* Maintenance and cleaning are streamlined with the ability to directly extract the output bearing seat, screw, and sealing device from the hopper.
* The PTFE gear-driven motor and screw offer a transitional buffer when encountering foreign objects, activating over-torque shutdown alarms to prevent damage to the gearbox or screw from unforeseen impacts.
* Advance connectivity with a reserved Ethernet communication interface supports remote control capabilities.
* Customers can select from PLC, MCU, or industrial computers, offering tailored control options.
* We provide program source codes for seamless integration with the client's upper computer systems and centralized factory control networks.

FAQs on Loss-in-Weight Feeders

1. How Does a Loss in Weight Feeder Work?

The gravimetric loss-in-weight feeder is an indispensable tool designed to meticulously control and accurately measure the flow rate of substances within a system. This innovative equipment excels at handling bulk solids, allowing them to discharge with a constant weight per unit time. Measurement is expressed in kg/min or Kg/hour, leveraging feedback control via weight signals. This system adeptly manages feed rates into instruments, incorporating platform scales, load-cells, and weigh hoppers. Depending on process needs, it may function as either a loss-in-weight or a gain-in-weight system.
