Product Description

Single Screw Loss-in-weight Feeders

General Introduction
Our innovative Loss-in-weight feeders are designed for precision. Perfect for small to medium feeding applications, they ensure optimal performance under ideal conditions, offering incredible flexibility. Capable of handling bulk solids, liquids, and even challenging materials, these feeders excel in continuous processes like extruder feeding, demanding high short-term consistency. Their versatility extends to the food industry and laboratories through tailored storage containers and adaptable feeding devices. With designs ranging from compact to modular, they meet diverse usage needs seamlessly.


Principle
The core principle of our loss-in-weight feeder is simple yet effective. As material flows through the feeder, the system's weight decreases. By controlling the feeder's feed rate, the rate of weight loss is meticulously adjusted to match the desired feed rate. Continuous monitoring ensures consistent material flow, making our feeders a benchmark in precision.
During operation, every component, from the feeder to the hopper and the material itself, is continuously weighed. This dynamic weighing ensures unmatched accuracy and reliability.
Gravimetric feeders, for example, experience minor feed rate fluctuations. These arise from variances in auger filling capacity and material bulk density. Our system compensates by adjusting auger speed, ensuring smooth and even product dispensing.

Composition of loss-in-weight feeder
Our state-of-the-art loss-in-weight feeders for bulk materials feature an array of components: storage hoppers, precision-controlled feeding devices such as augers, screws, agitators, and pumps. Additionally, they include scales or load cells, sophisticated loss-in-weight controllers, and feeder controllers, all orchestrated for peak performance.
Nanjing Pege's loss-in-weight feeders redefine adaptability for the compound industry. With flexible installation, diverse feeder sizes, and optimized hopper dimensions, our systems maximize available space. Vertical container walls enhance bulk material flow, and the off-centre auger arrangement allows up to six feeders to be arrayed side by side. Customizable drive and auger setups during assembly further underscore our commitment to tailored solutions.




1,Application field
Engineered for excellence, our feeders are ideal for handling resin granules, powder, and pellet blendings with unparalleled precision and reliability.

2,Features

• Our cutting-edge weighing scale employs a cantilever sling-type design, which supports the storage hopper. This design minimizes vibration, reduces interference, and accurately measures system flow by effectively isolating non-weight value disturbances.

*Stirring and feeding operations are independently driven to maintain ductile feed speed. Our variable speed ratios, tailored to material characteristics, enhance formula adjustment flexibility for customers.
*Utilizing a servo motor paired with a planetary reducer, our feeding motor ensures precise control, lightweight operation, minimal vibration, consistent low-speed torque, and a wide flow range—doubling the flow range of conventional AC motors.
* For ease of maintenance and cleaning, the output bearing seat, screw, and sealing device can be effortlessly extracted from the hopper.
* Our PTFE gear-driven motor and screw setup includes a transitional buffer function. In instances of foreign object interference, the system provides a motor over-torque shutdown alarm, safeguarding the gearbox and screw from damage.
* The electrical control system is equipped with an Ethernet communication interface for seamless remote control, ensuring modern connectivity.
* Offering versatility, we provide PLC, MCU, and industrial computers for customizable customer selection.
* We offer the program source code for integration with client systems and centralized factory control, facilitating streamlined operation and management.
