Product Description

Single Screw Loss-in-weight Feeders

General Introduction
NANJING PEGE TECHNO MACHINE CO., LTD. proudly presents the versatile and precision-driven PEGE Single Screw Loss-in-Weight Feeder, perfect for myriad feeding applications. These feeders masterfully function across small to medium ranges with unparalleled precision, given optimal ambient settings. Designed with flexibility in mind, they accommodate bulk solids, liquids, and even challenging flow products. Their utility spans across various continuous processes, notably feeding extruders where consistency is paramount. Additionally, they're pivotal in the food industry and laboratory environments, tailored with suitable storage and feeding mechanisms. Their design is customized—from compact to modular—to meet diverse application needs.


Principle
Innovatively engineered, the Loss-in-Weight Feeder operates on a principle where the system's overall weight diminishes as material is dispensed. By expertly controlling feed rates, the decrease in weight aligns seamlessly with the desired feed rate, ensuring flawless operation. This dynamic feedback system continually evaluates material flow, ensuring optimal performance.
During operation, the entire system—encompassing the feeder, hopper, and material—is continuously and precisely weighed, ensuring consistent monitoring and control at every stage.
For gravimetric feeders, slight variations in feed rates are a given. Such fluctuations are often due to changes in auger filling capacities or material bulk density. To counteract this, the feeder's auger speed is adeptly adjusted, guaranteeing a smooth and even product dispensing process.

Composition of Loss-in-Weight Feeder
Crafted with meticulous attention to detail, Loss-in-Weight Feeders for bulk materials integrate storage hoppers, controlled feeding devices—including augers, screws, agitators, and pumps—alongside scales or load cells, and sophisticated loss-in-weight controllers, ensuring precision in every aspect of their operation.
Nanjing Pege's Loss-in-Weight Feeders are innovatively tailored for the compound industry, boasting unparalleled flexibility and adaptability. With myriad installation options, varied feeder and hopper sizes, they optimize available space to the fullest. Their vertical container walls maximize capacity and improve bulk flow, while the clever off-center auger arrangement allows up to six feeders to be aligned perfectly. Customizable drive and auger setups during assembly make them ideal for diverse industrial applications.




1,Application Field
Designed for handling resin granules, powder, and pellet blends, the PEGE Single Screw Loss-in-Weight Feeder excels in managing diverse material types with precision.

2,Features

• The cantilever sling-type weighing scale ensures the storage hopper is well-supported, offering outstanding vibration reduction and anti-level interference. This advanced design effectively neutralizes non-weight value interference, enabling precise system flow measurement.

* With independent drives for stirring and feeding, the feeder offers exceptional ductility in feed speeds. Varied speed ratios adapt to material characteristics, enhancing customer formula flexibility.
* Equipped with a servo motor and planetary reducer, the feeding motor delivers precise control, light weight, low vibration, constant torque at low speeds, and an expansive flow range—doubling that of traditional AC motors.
* Convenience in maintenance and cleaning is ensured, as the output bearing seat, screw, and sealing device can be effortlessly extracted from the hopper.
* The PTFE gear-driven motor and screw provide a transitional buffer, safeguarding against foreign matter-induced jamming. It offers an over-torque shutdown alert, preventing gearbox or screw damage from impact deformation.
* The electrical control system is ahead of its time, featuring an Ethernet communication interface prepared for remote control connectivity.
* Clients have the freedom to choose between PLC, MCU, and industrial computer options, aligning with their specific operational needs.
* Source code access is available, facilitating integration with client upper computers and factory centralized control systems, enhancing system interoperability.

FAQs on Loss-in-Weight Feeders

1. How does a loss in weight feeder work?

A gravimetric loss-in-weight feeder is a sophisticated device crucial for controlling and precisely measuring the flow rate of materials within a system. This dynamic instrument handles bulk solids, enabling them to be discharged at a consistent weight per unit time, measured in kg/min or kg/hour. The weight information serves as a feedback-control system, meticulously monitoring and regulating the feed rate entering the apparatus. The weighing systems encompass various types, such as platform scales, load-cells, and weigh hoppers. Depending on the specific process requirements, the gravimetric feeder may function as either a loss-in-weight system or a gain-in-weight system.

1. What are the most important benefits the gravimetric feeder can offer you?

Guarantees superior quality of the final product by precisely metering bulk ingredients.
Dramatically reduces labor costs and enhances the working environment for personnel.
Enhances product stability and consistency.
Minimizes dust pollution, promoting a more environmentally friendly operation.

1. What is the general accuracy rate of a good loss-in-weight feeder?

Our feeders boast an impressive feeding accuracy rate of 0.5%, while the micro twin screw loss-in-weight feeder achieves an even more remarkable accuracy rate of up to 0.3%.

1. What is the lead time for the machine?
