Product Description

Twin Screw Loss-in-weight Feeders for Powder Blending

General Introduction

Our Loss-in-weight feeders are meticulously crafted to accommodate small to medium feeding ranges with unparalleled precision. These feeders operate flawlessly in ideal ambient conditions, offering flexibility to handle a diverse range of bulk solids, liquids, and even challenging flow products. They're pivotal in various continuous processes, especially in feeding extruders, which demand exceptional short-term feeding consistency. Extensively utilized in the food industry and laboratories, these feeders adapt seamlessly with suitable storage containers and feeding devices. Their design spectrum ranges from compact to modular, tailored to specific applications.


Principle
As materials pass through the feeder, the system's weight diminishes. By expertly managing the loss-in-weight feeder, the feed rate adjusts to align the weight loss speed with the desired rate. This continuous adjustment ensures uninterrupted flow monitoring and optimal performance.
During operation, every component and contained product are subjected to continuous weighing: the feeder, the hopper, and the material, ensuring precise control and efficiency.
Gravimetric feeders, though precise, experience slight feed rate fluctuations owing to variances in auger fill capacity and material bulk density. These are expertly compensated by adapting the auger speed, ensuring consistent and even product dispensing.

Features

1. The innovative cantilever type weighing frame provides a low center of gravity, enhancing stability with reduced vibration and superior anti-interference capabilities.
2. Designed with a vertical U-shaped hopper that boasts a mirror-like inner wall, our system eliminates material bridging for flawless operation.
3. Our Stainless Steel bellow sensor promises minimal deformation over time, delivering high precision with negligible signal drift, and enduring harsh environments.
4. With 485 Digital transmission, our weighing data ensures interference-free, consistent data transmission without attenuation.
5. Our innovative design separates feeding and stirring operations, featuring an independent agitation motor with adjustable stirring speed to meet precise requirements.
6. Positioned optimally, the absence of an agitation motor atop the hopper significantly reduces operational vibrations, achieving unparalleled stability and precision.

FAQs

1. How does a loss in weight feeder operate?

A gravimetric loss in weight feeder stands as a pivotal instrument, designed to meticulously control and measure the flow rate of substances within an intricate system. Masterfully engineered to manage bulk solids, this sophisticated equipment ensures a consistent discharge of material at a precise weight per unit of time, typically measured in kg/min or Kg/hour. By harnessing feedback control through weight signals, it adeptly monitors and regulates the feed rate entering the system. The weighing mechanisms encompass an array of examples, including platform scales, load-cells, and weigh hoppers, among others. Depending on the specific process requirements, these gravimetric feeders can function as either loss-in-weight systems or gain-in-weight systems, providing unparalleled versatility and precision.

1. What are the key advantages offered by a gravimetric feeder?

To assure the superior quality of the final product through precise metering of bulk ingredients, ensuring excellence and consistency.
To significantly reduce labor costs while enhancing the working environment for your workforce, contributing to increased efficiency and satisfaction.
