Product Description

Introducing the Precision Engineered Twin Screw Loss-in-weight Feeders for Exemplary Powder Blending

An All-Encompassing Overview

Experience unparalleled accuracy with our Loss-in-weight feeders, expertly designed for small to medium feeding ranges. These feeders excel under optimal ambient conditions, offering exceptional flexibility to adeptly manage bulk solids, liquids, and even challenging, poorly flowing products. They are integral to numerous continuous processes, such as feeding extruders that demand consistent short-term feeding precision. Additionally, they play a vital role in the food industry and laboratory settings, utilizing expertly designed storage containers and customized feeding devices. Our designs range from space-saving compact constructions to versatile modular concepts, tailored for diverse applications.


Operating Principle
As materials transit through the feeder, the system's weight gradually decreases. With precision control over the loss-in-weight feeder, the feed rate is meticulously adjusted to ensure the rate of weight loss aligns seamlessly with the predetermined feed target. Continuous monitoring of material flow guarantees accuracy.
During operation, every component, including the feeder, hopper, and material, undergoes continuous weighing to maintain top-notch accuracy.
Take, for example, gravimetric feeders: they experience slight feed rate fluctuations due to variations in the augers' filling capacity and material's bulk density. These are expertly counterbalanced by modifying the auger speed, ensuring that the product is dispensed with unwavering consistency.

Distinctive Features

1. A cantilever-type weighing frame ensures a lower center of gravity, minimizing vibrations and enhancing the feeder's anti-interference capabilities.
2. The vertical U-shaped hopper, with its mirror-like inner wall and absence of corner enclosures, prevents material bridging, ensuring seamless operations.
3. Our stainless steel bellow sensor boasts minimal deformation over time, high precision with negligible signal drift, and robustness for challenging environments.
4. The 485 Digital transmission system ensures data is transmitted without attenuation and is highly resistant to interference, safeguarding accuracy.
5. With independent operation for feeding and stirring, our design allows for precise control over stirring speed, tailored to your specific requirements.
6. Eliminating the agitation motor from the hopper's top reduces operational vibrations, delivering unmatched stability and precision.

Frequently Asked Questions

1. How does a loss in weight feeder operate?

A Gravimetric Loss in Weight Feeder is an essential instrument for precision in controlling and measuring the flow rate of a substance within a system. Engineered to proficiently handle bulk solids, it allows these materials to discharge consistently at a pre-determined weight per unit of time, using measurement units such as kg/min or Kg/hour. The weight data serves as a feedback mechanism for real-time control, meticulously regulating and monitoring the feed rate entering the instrument. This sophisticated weighing system includes a range of components like platform scales, load-cells, and weigh hoppers. Depending on the specific process requirements, the gravimetric feeder can function as either a loss-in-weight or gain-in-weight system.
