Product Description

Single Screw Loss-in-weight Feeders

General Introduction
Our cutting-edge Loss-in-weight feeders are meticulously engineered for small to medium feeding ranges, operating with unparalleled precision under optimal ambient conditions. Renowned for their versatility, these feeders seamlessly handle bulk solids, liquids, and even challenging, poorly flowing materials. They become indispensable assets across numerous continuous processes, such as extruder feeding, where remarkable short-term feeding consistency is paramount. The feeders find extensive use in the food industry and laboratories, thanks to customized storage containers and feeding devices. From compact designs to modular concepts, our feeders cater to diverse applications.


Principle
The principle behind the loss-in-weight feeder involves a fascinating process where feeding material leads to a reduction in system weight. By adeptly controlling the feeder, the feed rate is adjusted, ensuring the weight loss speed harmonizes with the desired feed rate. This exemplary control mechanism continually verifies material flow, achieving seamless operation.
During operation, every component, including the feeder, hopper, and material, is subjected to continuous weighing, guaranteeing precision at every step.
Gravimetric feeders display slight feed rate fluctuations, influenced by auger filling capacity and material bulk density. To maintain even product dispensing, these fluctuations are expertly compensated by adapting auger speeds, ensuring consistency and reliability.

Composition of loss-in-weight feeder
Expertly crafted for bulk materials, loss-in-weight feeders incorporate storage hoppers, precision-controlled feeding devices including augers, screws, agitators, pumps, and sophisticated scales or load cells. The advanced loss-in-weight controllers seamlessly manage the entire feeding process, ensuring optimal performance.
The Nanjing Pege's state-of-the-art loss-in-weight feeders are expertly optimized for the compound industry. With flexible installation options and diverse feeder and hopper sizes, they adapt seamlessly to any spatial arrangement. Vertical container walls maximize space efficiency and enhance bulk material flow. The innovative off-centre auger arrangement allows for up to six feeders to be positioned adjacently, while the drive and auger setup are customizable during assembly for tailored performance.




1,Application field
Ideal for resin granules, powder, and pellet blendings, our feeders excel in diverse application fields.

2,Features

• Innovatively designed, the cantilever sling-type weighing scale supports the storage hopper, boasting vibration reduction and anti-interference capabilities. It effectively neutralizes non-weight value interference from vibrators, ensuring remarkably accurate system flow measurement.

*Stirring and feeding mechanisms, independently driven, guarantee optimal feeding speed flexibility. With various speed ratios suited to material characteristics, customers experience unparalleled formula adjustment flexibility.
*Our feeding motor, featuring a servo motor coupled with a planetary reducer, offers precise control, lightweight design, minimal vibration, consistent low-speed torque, and an impressive range of flow, doubling that of conventional AC motors.
* The innovative design allows the output bearing seat, screw, and sealing device to be effortlessly removed from the hopper for easy, efficient maintenance and cleaning.
* The motor and screw, powered by PTFE gear, provide a transitional buffer function when foreign matter causes a screw jam, triggering an over-torque shutdown alarm to safeguard the gearbox and screw from damage.
* Our sophisticated electrical control system includes an Ethernet communication interface, enabling seamless remote control capability.
* Customers can choose from PLC, MCU, and industrial computer options, offering unparalleled flexibility and control.
* We offer program source code access for seamless integration with the client's upper computer and factory centralized control system, ensuring comprehensive connectivity.
