Product Description

Single Screw Loss-in-weight Feeders

General Introduction
The Loss-in-weight feeders cater perfectly to small and medium feeding ranges, offering unparalleled precision under optimal conditions. Their adaptability is unmatched, handling everything from bulk solids and liquids to hard-to-flow materials with ease. These feeders excel in continuous processes, providing consistent feeding for extruders. Widely utilized in the food industry and laboratories, they come equipped with suitable storage containers and customized feeding devices. Versatility in design ranges from compact to modular, tailored to specific applications.


Principle
In operation, as material flows through the feeder, the system's weight diminishes. The feeder adjusts feed rates to ensure the speed of weight reduction mirrors the required feed rate. This continuous monitoring guarantees smooth material flow.
During operation, every component including the feeder, hopper, and material is constantly weighed.
Gravimetric feeders experience slight feed rate variations, attributed to changes in auger filling capacity and material bulk density. These variations are counteracted by modifying auger speeds, ensuring uniform product dispensing.

Composition of loss-in-weight feeder
Bulk-material loss-in-weight feeders comprise storage hoppers, precise feeding devices like augers, screws, agitators, and pumps, alongside scales or load cells, all managed by sophisticated loss-in-weight controllers.
Nanjing Pege's loss-in-weight feeders are optimized for the compound industry, offering flexible installation, variable feeder and hopper sizes to maximize space efficiency. Vertical container walls enhance bulk material flow, while the off-center auger setup allows for six feeders to be aligned side-by-side. Customizable drive and auger settings during assembly provide further adaptability.




1,Application field
Ideal for resin granules, powder, and pellet blending.

2,Features

• The cantilever sling-type weighing scale supports the storage hopper, featuring vibration reduction and anti-level interference, ensuring precise flow measurement by shielding non-weight value interference.

*Separation of stirring and feeding with independent drives ensures flexible feeding speeds, allowing customization according to material characteristics for optimized formula adjustments.
*Utilizing a servo motor and planetary reducer, the feeding motor delivers precise control with lightweight design, minimal vibration, consistent low-speed torque, and a flow range double that of AC motors.
* Ease of maintenance and cleaning is ensured with the direct pull-out design of the output bearing seat, screw, and sealing device from the hopper.
* The PTFE gear-driven motor and screw provide a transitional buffer function, preventing gearbox or screw damage from impact deformation by issuing an over-torque shutdown alarm when foreign matter causes screw obstruction.
* The electrical control system includes an Ethernet communication interface for seamless remote control capabilities.
* Options for PLC, MCU, and industrial computers are available to suit customer preferences.
* We can supply the program source code, facilitating integration with the client's upper computer and centralized factory control system.
