Product Description

Introducing our innovative Twin Screw Loss-in-weight Feeders, meticulously engineered for exceptional powder blending efficiency.

General Introduction

Loss-in-weight feeders, designed for precision across small to medium feeding capacities, operate with unparalleled accuracy, given optimal ambient conditions. Their versatility is unmatched, capable of handling bulk solids, liquids, and even challenging, poorly flowing materials. These feeders find a broad spectrum of applications in continuous processes that demand precise feeding, such as extruders requiring short-term consistency. Additionally, their utility extends to the food industry and laboratories, facilitated by customizable storage solutions and feeding devices. The design spectrum ranges from compact, space-saving structures to versatile modular concepts, tailored to specific user needs.


Principle
In operation, as materials traverse through the feeder, the system's weight diminishes. By managing the loss-in-weight feeder, the feed rate is meticulously adjusted, ensuring the speed of weight reduction aligns perfectly with the desired feed rate. Continual monitoring ensures a consistent material flow, maintaining operational integrity.
Every component within the system, including the feeder, hopper, and material, undergoes continuous weighing during operation, ensuring precision and consistency.
Gravimetric feeders may exhibit minor feed rate fluctuations, stemming from variations in auger filling capacity and material bulk density. These are seamlessly compensated by adjusting the auger speed, guaranteeing even product distribution and maintaining product uniformity.

Features

1. Our cantilever weighing frame design boasts a lower barycenter, minimizing vibration and offering superior anti-interference performance, ensuring stability and accuracy of the entire feeder system.
2. The vertical U-shaped hopper, with its seamless mirror-finish inner walls, prevents material bridging and ensures smooth material flow.
3. Our stainless steel bellow sensor exhibits minimal deformation even after prolonged use. It is highly precise, with negligible signal drift, making it ideal for harsh environments.
4. The 485 digital transmission protocol ensures weighing data is transmitted with zero attenuation and robust anti-interference capabilities.
5. Feeding and stirring operations are independently managed via separate motors, allowing for customizable stirring speeds tailored to specific demands.
6. Eliminating the agitation motor from the hopper's top significantly reduces operational vibration, enhancing system stability and precision.

FAQs

1. How does a loss in weight feeder work?

A gravimetric loss in weight feeder is a sophisticated instrument critical for controlling and measuring the material flow within an industrial system. This remarkable equipment expertly handles bulk solids, enabling them to be discharged at a consistent weight per unit of time, precisely measured in kg/min or kg/hour. Through an advanced feedback control system, signals about the material's weight are used to meticulously monitor and regulate the feed rate entering the system. The weighing systems are comprehensive, including platform scales, load-cells, weigh hoppers, and more. Depending on the specific process requirements, the gravimetric feeder may operate as either a loss-in-weight system or a gain-in-weight system, showcasing its versatility and precision.
