Product Description

Discover the Excellence of Twin Screw Loss-in-weight Feeders for Expert Powder Blending

Comprehensive Overview

Our Loss-in-weight feeders shine with versatility, catering to small and medium feeding ranges. These devices deliver impeccable precision, thriving in optimal ambient conditions. Their adaptability extends to handling bulk solids, liquids, and even difficult-to-flow products. Employed in various continuous processes, they excel in feeding extruders demanding high short-term feeding consistency. Beyond industrial applications, their utility spans into the realms of food production and laboratory environments, facilitated by specialized storage and feeding apparatus. The design spectrum ranges from compact to modular, ensuring a perfect fit for diverse applications.


Operating Principle
As the material progresses through the feeder, the system's weight experiences a decrease. By regulating the loss-in-weight feeder, the feed rate is adjusted so that the speed of weight reduction aligns seamlessly with the targeted feed rate. The system's controls continuously monitor the material flow, ensuring precision and consistency.
During operation, a meticulous weighing process is applied to all components and any product they encompass: the feeder, the hopper, and the material.
Gravimetric feeders, for instance, may encounter minor feed rate fluctuations due to variations in auger filling capacity and the material's bulk density. However, these are expertly counterbalanced by fine-tuning the auger speed, thereby guaranteeing an even product distribution.

Product Features

1. The ingenious cantilever-type weighing frame ensures a low barycenter, significantly reducing vibration and enhancing the feeder's anti-interference capabilities.
2. Featuring a vertical U-shaped hopper with a polished inner surface and no corner enclosures, it effectively prevents material bridging.
3. Our Stainless Steel bellow sensor is engineered for longevity, showcasing minimal deformation over extended use, high precision with negligible signal drift, and robust performance in harsh environments.
4. Utilizing 485 Digital transmission, the weighing data is safeguarded against attenuation and interference, ensuring seamless data flow during transmission.
5. The feeder and stirring mechanisms operate independently, with adjustable stirring speeds tailored to specific demands.
6. Our design eliminates the need for an agitation motor atop the hopper, significantly reducing operational vibration to achieve exceptional stability and precision.
