Product Description

Twin Screw Loss-in-weight Feeders for Powder Blending

General Introduction

Loss-in-weight feeders, crafted for precision in small to medium feeding ranges, stand as a testament to efficiency and flexibility. Operating with remarkable precision under optimal conditions, they excel in delivering consistent results whether handling bulk solids, liquids, or challenging materials. Ideal for continuous processes like extruder feeding that demand unparalleled consistency, these feeders also find their place in the food industry and laboratories, adapting to various storage and feeding configurations. Their designs range from compact to modular, tailored to meet diverse applications.


Principle
As material moves through the feeder, the system's weight diminishes. The feeder's control mechanism adjusts the feed rate, ensuring the speed of weight loss aligns with the desired rate. This continuous monitoring guarantees a seamless flow of materials.
Throughout operation, every component and product within the feeder, hopper, and material are weighed continuously, ensuring precise monitoring and control.
Gravimetric feeders, despite slight feed rate fluctuations due to variables like auger filling capacity and material bulk density, maintain even product dispensing by adjusting auger speed to compensate.

FAQs

1. How does loss in weight feeder work?

The Gravimetric Loss in Weight Feeder is an essential instrument designed to precisely control and measure the flow rate of substances within system environments. This advanced equipment expertly manages bulk solids, enabling them to discharge consistently at set weights per time unit, such as kg/min or kg/hour. It utilizes weight signals as part of an integrated feedback control system, ensuring precise monitoring and regulation of the feed rate into the instrument. The feeder's weighing systems incorporate various technologies, including platform scales, load-cells, and weigh hoppers. Depending on the specific process requirements, the gravimetric feeder may operate as either a loss-in-weight or gain-in-weight system, providing unparalleled flexibility and precision.

1. What are the prominent advantages that the gravimetric feeder can offer you?

To guarantee superior quality in the final product through precise metering of bulk ingredients, ensuring consistently excellent results.
To significantly lower labor costs while simultaneously enhancing the working environment for employees, promoting efficiency and well-being.
To enhance product stability, ensuring consistent and reliable performance in every batch produced.
To minimize dust pollution, aligning with environmentally friendly practices and contributing to a cleaner, greener operation.

1. What is the standard accuracy rate of a quality loss in weight feeder?

Our standard feeder boasts an impressive feeding accuracy rate of 0.5%. Our micro twin screw loss in weight feeder takes precision even further, achieving an exceptional accuracy rate of up to 0.3%.

1. What components form the core of a typical loss in weight feeder?

Loss-in-weight feeders for bulk materials are composed of several key elements: a storage hopper, controlled feeding devices like augers, screws, chutes, or pumps, and crucial scales or load cells. They are equipped with sophisticated loss-in-weight controllers. Additionally, optional components such as agitators may be included to enhance the quality and consistency of bulk materials.
