Product Description

Single Screw Loss-in-weight Feeders

General Introduction
Loss-in-weight feeders are marvels of engineering designed for both small and medium feeding ranges. These precision instruments perform with unparalleled accuracy under optimal conditions, showcasing impressive versatility. They adeptly handle an array of materials, including bulk solids, liquids, and even those that are challenging to flow. These feeders are indispensable in continuous processes, particularly when feeding extruders that demand exceptional short-term feeding consistency. Their utility extends across diverse sectors, including the food industry and laboratory settings, where they seamlessly integrate with suitable storage containers and customized feeding devices. Depending on the application, designs range from compact, space-efficient models to modular concepts tailored for specific uses.


Principle
The operational magic of a loss-in-weight feeder lies in its precise control over material feed. As material is introduced into the system, its weight decreases. By regulating the feeder, the rate of feed is finely tuned, ensuring the speed of weight loss aligns perfectly with the desired feed rate. These controls continuously monitor the material flow, maintaining constant vigilance over the feeding process.
During operation, every component—whether it's the feeder, hopper, or material—undergoes continuous weighing. This ensures that the system operates with impeccable precision, accounting for every nuance of the material's weight throughout the process.
Gravimetric feeders, like finely tuned instruments, exhibit slight variations in feed rates due to factors such as auger filling capacity and material bulk density. These subtle fluctuations are skillfully managed by adjusting the auger speed, delivering a consistent and even product flow.

Composition of loss-in-weight feeder
The architecture of loss-in-weight feeders for bulk materials is both sophisticated and efficient. These systems comprise storage hoppers, intricately controlled feeding devices such as augers, screws, agitators, and pumps. They also feature precision scales or load cells, along with advanced loss-in-weight controllers that oversee the entire feeding process with remarkable accuracy.
Nanjing Pege's loss-in-weight feeders have been meticulously optimized for the compound industry. Offering flexibility in installation, various feeder sizes, and customizable hopper dimensions, these feeders make efficient use of every available space. Their vertical container walls maximize capacity, enhancing bulk material flow. The unique off-centre auger design allows the convenient arrangement of up to six feeders side by side, while the drive and auger configurations can be tailored during assembly to suit specific needs.




1,Application field
Ideal for resin granules, powder, and pellet blendings, these feeders offer precision and adaptability across a spectrum of applications.

2,Features

• The cantilever sling-type weighing scale, supporting the storage hopper, is engineered for superior performance. It minimizes vibration and interference, effectively shielding against non-weight value disturbances, thereby ensuring an accurate measurement of system flow.

* The separation of stirring and feeding with independent drive systems guarantees a feeding speed that is both flexible and controlled. By selecting various speed ratios based on material characteristics, it enhances the adaptability of customer formulations.
* Employing a servo motor paired with a planetary reducer, the feeding motor provides precise control, lightweight construction, minimal vibration, and consistent low-speed torque. This setup offers a flow range that doubles that of traditional AC motors.
* Designed for ease of maintenance and cleaning, the output bearing seat, screw, and sealing device can be effortlessly extracted from the hopper.
* Engineered with a PTFE gear-driven motor and screw, the system includes a transitional buffer function. This feature triggers an over-torque shutdown alarm when the screw encounters foreign obstruction, protecting the gearbox and screw from damage.
* The advanced electrical control system features an Ethernet communication interface, facilitating seamless remote control.
* Customers have the flexibility to choose from PLC, MCU, and industrial computer control options to best meet their operational needs.
* We offer access to the program source code, enabling integration with the client's upper computer and factory centralized control systems.
