Product Description

Single Screw Loss-in-weight Feeders

General Introduction
Loss-in-weight feeders are the epitome of precision for both small to medium feeding requirements, maintaining unparalleled accuracy in ideal conditions. Their versatility allows them to adeptly handle bulk solids, liquids, and even products with challenging flow characteristics. Widely utilized in continuous processes demanding exceptional short-term feeding consistency, such as extruder feeding, they also find applications in the food industry and laboratories with suitable storage containers and feeding devices. Depending on the usage scenario, designs range from compact configurations to sophisticated modular layouts.


Principle
As material is dispensed from the feeder, the system's weight diminishes, and the loss-in-weight feeder's control mechanisms adjust the feed rate. This ensures the rate of weight loss aligns perfectly with the desired feed rate, with continuous checks to verify smooth material flow.
Throughout operation, all components, including any contained product, are constantly weighed: the feeder, the hopper, and the material itself.
Gravimetric feeders experience minor fluctuations in feed rates due to variations in auger filling capacity and bulk material density. These are expertly countered by adjusting auger speed, ensuring consistent product dispensing.

Composition of loss-in-weight feeder
Loss-in-weight feeders for bulk materials are equipped with storage hoppers, precisely controlled feeding devices like augers, screws, agitators, pumps, alongside scales or load cells, and sophisticated loss-in-weight controllers.
The Nanjing Pege's loss-in-weight feeders are meticulously optimized for the compound industry, offering flexible installation options, various feeder and hopper sizes tailored to available spaces. The vertical container walls maximize every millimeter, enhancing bulk material flow. Unique off-center auger arrangements allow up to six feeders to be arrayed side-by-side, with customizable drive and auger setups during assembly.




1,Application field
Perfectly suited for resin granules, powder, and pellet blendings.

2,Features

• The cantilever sling-type weighing scale, supporting the storage hopper, boasts vibration reduction and anti-level interference capabilities. It effectively isolates non-weight value interference from vibrations, ensuring accurate system flow measurement.

*The stirring and feeding mechanisms are independently driven, allowing the feeding speed to remain adaptable. Various speed ratios are selected based on material characteristics, enhancing customer formula flexibility.
*The feeding motor utilizes a cutting-edge servo motor combined with a planetary reducer for precise control. This results in a lightweight design with minimal vibration, consistent low-speed torque, and an expansive flow range, doubling that of traditional AC motors.
* Maintenance and cleaning are simplified with the design allowing the output bearing seat, screw, and sealing device to be effortlessly removed from the hopper.
* The motor and screw, driven by resilient PTFE gears, provide a transitional buffer when encountering foreign matter. This feature triggers an over-torque shutdown alarm, safeguarding the gearbox and screw from impact damage.
* The advanced electrical control system includes an Ethernet communication interface, facilitating seamless remote control capabilities.
* Customers can choose from PLC, MCU, or industrial computer control options, offering flexibility and customization.
* We offer program source code access for integration with the client's upper computer and centralized factory control systems.

FAQs on Loss-in-Weight Feeders

1. How does a loss-in-weight feeder operate?

The gravimetric loss-in-weight feeder is a crucial instrument designed to control and precisely measure the flow rate of a substance within a systemic setup. This remarkable equipment is adept at managing bulk solids, enabling a consistent discharge at a fixed weight per unit of time, typically measured in kg/min or kg/hour. The weight signal serves as a feedback control mechanism, adeptly overseeing and regulating the feed rate into the instrument. The weighing systems encompass various examples 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 or gain-in-weight system.
