Product Description

Single Screw Loss-in-weight Feeders

General Introduction
PEGE's Loss-in-weight feeders are engineered to excel in diverse feeding ranges, from small to medium capacities. They operate with unparalleled precision under ideal ambient conditions, showcasing remarkable versatility. Capable of managing bulk solids, liquids, and even challenging products with poor flow characteristics, they become indispensable in continuous processes like extruder feeding where short-term consistency is critical. These feeders also find extensive use in the food industry and laboratory settings, adapting seamlessly thanks to their versatile storage options and feeding devices. With designs ranging from compact to modular, they cater to varying application needs.


Principle
The innovative design of the loss-in-weight feeder allows for precise control of feed rates. As materials pass through, the system's weight naturally decreases. The feeder adjusts the feed rate to ensure the speed of weight loss is perfectly aligned with the desired rate. Continuous monitoring ensures material flow remains consistent, optimizing performance.
During operation, every component and material within the system—including the feeder, hopper, and material—are meticulously weighed to guarantee constant accuracy and reliability.
Gravimetric feeders are designed to counteract any slight feed rate fluctuations. These variations, stemming from changes in the augers' filling capacity and the material's bulk density, are expertly compensated by adjusting the auger speed, ensuring smooth, uniform product distribution.

Composition of loss-in-weight feeder
Nanjing Pege's loss-in-weight feeders are intricately composed for efficiency in handling bulk materials. They include storage hoppers, precise feeding devices like augers, screws, agitators, pumps, and sophisticated scales or load cells. The advanced loss-in-weight controllers, or feeder controllers, orchestrate seamless operations.
Tailored for the compound industry, the Nanjing Pege feeders boast optimized designs. They offer flexible installation setups, various feeder sizes, and adjustable hopper sizes to make the most out of available space. The vertical container walls maximize millimetre usage, enhancing bulk material flow. The innovative off-centre auger arrangement permits up to six feeders to be strategically placed side by side, and the drive and auger setup can be customized during assembly for ultimate flexibility.




1,Application field
Efficiently caters to resin granules, powder, and pellet blendings.

2,Features

• Designed with a cantilever sling-type weighing scale, the system supports the storage hopper with anti-vibration and anti-interference features. This ensures accurate flow measurement by minimizing non-weight value disruptions from vibratory influences.

*Stirring and feeding mechanisms operate independently, driven separately to maintain adaptive feeding speeds. Various speed ratios are selectable based on material characteristics, allowing enhanced flexibility for customer-specific formula adjustments.
*The use of a servo motor paired with a planetary reducer ensures precise control, offering light weight, minimal vibration, constant torque at low speeds, and a broad flow range—doubling the flow capacity compared to traditional AC motors.
* Streamlined maintenance and cleaning are facilitated by the design, allowing the output bearing seat, screw, and sealing device to be easily withdrawn from the hopper.
* Equipped with PTFE gear-driven motors and screws, the design provides a buffer function during screw obstructions by foreign matter. This grants the motor over-torque shutdown time to prevent any damage to the gearbox or screw from impact deformation.
* An Ethernet communication interface is integrated into the electrical control system, offering capabilities for remote control.
* Choose from PLC, MCU, and industrial computer options to tailor the system to your specific requirements.
* Program source code available for seamless integration with the client's upper-level 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 a sophisticated instrument designed for precise control and measurement of substance flow in complex systems. It expertly handles bulk solids, allowing discharge at a consistent weight per unit time, measured in kg/min or kg/hour. The weight signal is crucial for feedback control, managing and monitoring feed rates entering the system. Weighing systems like platform scales, load-cells, and weigh hoppers are integral to its operation. Depending on process requirements, the gravimetric feeder may function as either a loss-in-weight or gain-in-weight system.
