Product Description

Twin Screw Loss-in-weight Feeders for Powder Blending

General Introduction

Our advanced Loss-in-weight feeders excel in delivering unparalleled precision across small to medium feeding ranges. Designed to perform with utmost accuracy under optimal conditions, these feeders are impressively versatile, effortlessly managing bulk solids, liquids, and even challenging, poorly flowing materials. They are integral to numerous continuous processes, notably in feeding extruders where exceptional short-term feeding consistency is crucial. Moreover, they find substantial applications in the food industry and laboratories, equipped with specialized storage solutions and customized feeding devices. Choose from compact designs to modular systems, tailored precisely to meet your application needs.


Principle
Experience the precision of our loss-in-weight feeder system—where as materials pass through, the system's weight decreases seamlessly. By continuously monitoring the weight loss, the feeder adjusts the feed rate perfectly, aligning the speed of weight reduction with the desired feeding rate. Ensure smooth operation as our control mechanisms meticulously verify the material's flow.
During continuous operation, every component, including the feeder, hopper, and material, undergoes persistent weighing, ensuring exemplary consistency and reliability.
Gravimetric feeders, renowned for their precision, do exhibit minor feed rate fluctuations. These arise from variances in auger filling and material bulk density but are adeptly counterbalanced by adjusting auger speed, ensuring a uniform dispensing of the product.

Twin Screw Loss-in-weight Feeders

Application material
Our feeders are engineered to handle a variety of materials including Resin Granules, Resin Powder, Calcium Carbonate, French Chalk, Tio2, and Carbon Black with precision and ease.

Features

1. The Cantilever weighing frame ensures a lower barycenter, reducing vibrations and enhancing the anti-interference capabilities for the entire feeder, ensuring precision and stability.
2. The Vertical U-shaped hopper, featuring a mirror-like inner surface and free from corner enclosures, guarantees a bridge-free material flow, optimizing performance.
3. Our Stainless Steel bellow sensor is engineered for long-term durability, showcasing minimal deformation and high precision with minimal signal drift, perfect for challenging environments.
4. Utilizing 485 Digital transmission, weighing data is transmitted with exceptional accuracy, free from attenuation and interference throughout the process.
5. Feeding and stirring operate independently with our dedicated agitation motor, allowing tailored stirring speeds to meet exact demands.
6. Eliminating the need for an agitation motor atop the hopper reduces operational vibrations, achieving unparalleled stability and precision.
