Product Description

Single Screw Loss-in-weight Feeders

General Introduction
Exuding precision and versatility, loss-in-weight feeders from Nanjing Pege are ideal for small to medium feeding ranges. With an outstanding precision accuracy of 0.5%, these feeders excel under optimal ambient conditions, catering to a range of materials including bulk solids, liquids, and challenging-to-handle products. Their flexibility allows them to be pivotal across various continuous processes, notably in feeding extruders that demand consistent short-term feeding. These feeders find applications in the food sector and laboratory environments, employing suitable storage containers and customized feeding devices. The design spectrum varies from compact to modular, tailored to specific application needs.


Principle
Ingeniously engineered, when material passes through our feeder, the system's weight decreases. The sophisticated control of the loss-in-weight feeder adjusts the feed rate, ensuring that the speed of weight loss aligns seamlessly with the desired feed rate. Continuous monitoring by the feeder controls guarantees uninterrupted material flow assessments.
Every component and contained product is meticulously weighed throughout operations. This includes the feeder, hopper, and material, ensuring utmost accuracy and consistency.
Gravimetric feeders may exhibit minor feed rate fluctuations, often due to variations in auger filling capacity and material bulk density. These are expertly corrected by adjusting the auger speed, ensuring a smooth and even product dispensing process.

Composition of loss-in-weight feeder
Our advanced loss-in-weight feeders for bulk materials are composed of storage hoppers, precision-controlled feeding devices such as augers, screws, agitators, and pumps, alongside scales or load cells, and sophisticated loss-in-weight controllers.
Nanjing Pege's loss-in-weight feeders are meticulously optimized for the compound industry. Offering flexible installation options, various feeder and hopper sizes adapt to any spatial constraints. The innovative vertical container design maximizes space utility and enhances bulk material flow. With an off-centre auger arrangement, up to six feeders can be efficiently positioned side by side. Our customizable drive and auger configurations ensure maximum operational efficacy during assembly.




1,Application field
Expertly crafted for resin granules, precise powder handling, and efficient pellet blending applications.

2,Features

• Our innovative cantilever sling-type weighing scale supports the storage hopper, offering superior vibration reduction and counteracting level interference. It effectively isolates non-weight value interference, thus ensuring precise system flow measurements.

* With independently driven stirring and feeding mechanisms, our system guarantees a feeding speed that is finely adaptable. Various speed ratios can be selected according to material properties, enhancing the flexibility for customer-specific formula adjustments.
* The feeding motor integrates a servo motor with a planetary reducer for precise control, lightweight design, minimal vibration, constant low-speed torque, and double the flow range compared to an AC motor.
* The innovative design allows the output bearing seat, screw, and sealing device to be effortlessly removed from the hopper, facilitating easy maintenance and cleaning.
* Our PTFE gear-driven motor and screw provide a buffer function when foreign matter jams the screw, enabling an over-torque shutdown alarm. This feature protects the gearbox and screw from damage due to impact deformation.
* The electrical control system includes an Ethernet communication interface, paving the way for seamless remote control.
* Customers can choose from PLC, MCU, and industrial computer options tailored to their specific needs.
* We offer program source code access for integration with the client's upper computer and factory-wide centralized control systems.
