Product Description

Introducing the Twin Screw Loss-in-weight Feeders: Versatile Solutions for Powder Blending Excellence

General Introduction

Our state-of-the-art loss-in-weight feeders are designed for small to medium feeding ranges and deliver unmatched precision in optimal ambient conditions. These feeders offer incredible versatility, handling bulk solids, liquids, and even challenging, poorly flowing products with ease. Perfectly suited for a myriad of continuous processes, they are indispensable for feeding extruders that demand exceptional short-term feeding consistency. These feeders also excel in the food industry and laboratory settings, thanks to their compatibility with specialized storage containers and adaptive feeding devices. From compact designs to modular concepts, our feeders adapt seamlessly to meet diverse usage requirements.


Principle
As material flows through the feeder, the system's weight decreases in a controlled manner. The dynamic loss-in-weight feeder adjusts the feed rate, ensuring the weight loss speed aligns perfectly with the desired feeding rate. This sophisticated control continuously monitors the material flow, guaranteeing precision.
During operation, each component, including the feeder, hopper, and material, is continuously weighed, ensuring precise and accurate feeding.
Gravimetric feeders experience minor fluctuations in feed rates, primarily due to variations in auger filling capacity and material bulk density. To counteract these fluctuations, the system automatically adjusts the auger speed, ensuring a consistent and even product dispensation.

Features

1. Our cantilever-type weighing frame ensures a lower center of gravity, providing superior vibration resistance and anti-interference performance throughout the feeding process.
2. The vertical U-shaped hopper, featuring a mirror-smooth inner surface and free from corner enclosures, prevents material bridging, ensuring smooth and uninterrupted flow.
3. Equipped with a stainless steel bellow sensor, our feeders boast high precision with minimal signal drift, ensuring durability even in harsh environments.
4. The 485 Digital transmission system ensures weighing data is transmitted without attenuation and remains interference-free, maintaining accuracy.
5. With independent feeding and stirring functions operated by separate motors, the stirring speed can be fine-tuned to meet specific demands, enhancing performance.
6. Our innovative design eliminates the need for an agitation motor atop the hopper, reducing operational vibration and achieving exceptional stability and accuracy.
