Product Description

Twin Screw Loss-in-weight Feeders for Powder Blending

General Introduction

Experience unmatched accuracy with our cutting-edge Loss-in-weight feeders, masterfully crafted for both small and medium feeding capacities. Designed to thrive in optimal ambient conditions, these feeders excel in handling a vast array of materials, including bulk solids, liquids, and even those notoriously difficult and poorly-flowing substances. Engineered for excellence in continuous processes, they are particularly adept at feeding extruders where maintaining short-term feeding consistency is crucial. Ideal for use across a multitude of industries, from food processing to laboratory environments, they come equipped with specialized storage containers and bespoke feeding devices. With design options ranging from compact to modular, these feeders seamlessly adapt to any application requirement.


Principle
As material passes through the feeder, the system's weight continuously decreases. This sophisticated loss-in-weight control ensures that the feed rate is meticulously adjusted, so the speed of weight reduction matches precisely with the intended feed rate. Constant monitoring is in place to verify the smooth flow of material, guaranteeing optimal performance every step of the way.
During operation, each component, including the feeder, hopper, and material, is weighed with precision throughout, ensuring consistent and accurate performance without fail.
Gravimetric feeders are designed to handle minor fluctuations in feed rate, which can occur due to changes in auger fill capacity and material bulk density. These fluctuations are expertly managed by dynamically adjusting the auger speed, ensuring the product discharge remains consistently even, delivering smooth and reliable operation at all times.

As material is dispensed, the rate of weight reduction is calculated with precision, and the feeder speed is meticulously adjusted to maintain the exact desired rate.

Twin Screw Loss-in-weight Feeders

Application material
Our Twin Screw Loss-in-weight Feeders are proficiently designed to handle a diverse range of materials, including Resin Granules, Resin Powder, Calcium Carbonate, French Chalk, TiO2, and Carbon Black, ensuring versatility and adaptability.

Features

1. The cantilever-type weighing frame is ingeniously designed to maintain a lower center of gravity, significantly reducing vibrations and enhancing the anti-interference performance of the entire feeder for superior stability.
2. The vertical U-shaped hopper features a mirror-polished inner wall with no corner enclosures, effectively preventing material bridging and ensuring an uninterrupted, smooth operational flow.
3. Our feeders are equipped with a stainless steel bellow sensor, delivering exceptional precision with minimal signal drift, and are built to endure long-term use even in the harshest environments.
4. Utilizing 485 Digital transmission, the integrity of the weighing data remains intact with no attenuation, providing robust anti-interference throughout data transmission.
5. Our feeders boast independent motors for feeding and stirring, allowing the stirring speeds to be precisely adjusted to meet specific demands, ensuring efficiency and precision.
6. By strategically eliminating the agitation motor from the hopper's top, vibrations are notably reduced, contributing to the system's remarkable stability and accuracy.
