Product Description

Single Screw Loss-in-weight Feeders

General Introduction
Discover unparalleled accuracy and adaptability with our Loss-in-weight Feeders, perfect for small to medium feeding ranges. Engineered to perform with exceptional precision, these feeders excel in ideal ambient conditions. Their versatility allows them to handle a variety of materials, from bulk solids and liquids to challenging flow products. Vital in continuous processes like extruder feeding, they ensure unmatched short-term consistency. Their applications span across the food industry and laboratories, utilizing tailored storage solutions and feeding mechanisms. Designs range from compact setups to modular systems, tailored to meet diverse needs.


Principle
As materials are fed, the system's weight diminishes. The innovative control of our loss-in-weight feeder adjusts the feed rate, ensuring the weight loss corresponds precisely with the desired rate. Continuous monitoring of flow keeps the feeder's performance in check, aligning operation with your demands.
Every component, inclusive of any product within, is continuously weighed throughout operation: the feeder, hopper, and material are all under constant surveillance.
Gravimetric feeders experience minor feed rate fluctuations due to variations in auger fill capacity and material bulk density. By adjusting auger speed, these fluctuations are compensated, ensuring a seamless and consistent product dispensation.

Composition of loss-in-weight feeder
Engineered for precision, our loss-in-weight feeders for bulk materials feature storage hoppers, controlled feeding devices like augers, screws, and pumps. Scales or load cells, alongside sophisticated loss-in-weight controllers, ensure optimal control and efficiency.
The Nanjing Pege loss-in-weight feeders are expertly optimized for the compound industry, offering unrivaled installation flexibility. With a variety of feeder and hopper sizes, they adapt to any space constraints. Vertical container walls optimize material flow, while a unique off-centre auger design allows for up to six feeders side-by-side. Drive and auger setups remain customizable, even during assembly, for maximum efficiency.




1,Application field
Tailored for resin granules, powder, and pellet blendings, our feeders deliver precision and versatility across diverse applications.

2,Features

• Our cantilever sling-type weighing scale supports the storage hopper, effectively dampening vibrations and shielding against non-weight value interference for precise flow measurement.

* With independent stirring and feeding drives, the feeding speed remains adaptable. Various speed ratios can be selected based on material characteristics, enhancing formula flexibility for customers.
* The feeder employs a servo motor with a planetary reducer, offering precise control, lightweight design, minimal vibration, low-speed constant torque, and an extensive flow range, doubling that of an AC motor.
* Maintenance and cleaning are simplified with easy removal of the output bearing seat, screw, and sealing device directly from the hopper.
* Driven by PTFE gears, the motor and screw benefit from a transitional buffer if blocked by foreign objects, providing over-torque shutdown alarm time, protecting the gearbox and screw from damage.
* Equipped with an Ethernet communication interface, the electrical control system allows for seamless remote control integration.
* A selection of PLC, MCU, and industrial computers is available to meet customer needs.
* Providing the program source code facilitates integration with the client's upper computer and centralized factory control system.

FAQs on Loss-in-Weight Feeders

1. How does a loss in weight feeder work?

The gravimetric loss in weight feeder is an essential tool for precisely controlling and measuring the flow rate of materials within a system. It is adept at handling bulk solids, permitting a discharge at a consistent weight per unit of time, such as kg/min or kg/hour. The weight feedback acts as a control mechanism, regulating the feed rate into the system. This sophisticated weighing system might include platform scales, load-cells, weigh hoppers, and more. Whether it operates as a loss-in-weight or gain-in-weight system depends on the specific process needs.

1. What are the most important benefits the gravimetric feeder offers?

They ensure the supreme quality of the final product through precise metering of bulk ingredients.
They minimize labor costs and significantly enhance the working environment.
