Product Description

Twin Screw Loss-in-weight Feeders for Powder Blending

General Introduction

Loss-in-weight feeders are sophisticated devices ideal for small to medium feeding applications. With remarkable precision, they function seamlessly under optimal ambient conditions. Versatile and robust, they can effortlessly manage bulk solids, liquids, and even challenging, poorly flowing materials. These feeders are integral to numerous continuous processes, such as feeding extruders, where consistent, short-term feeding is crucial. Their adaptability extends to the food industry and laboratory settings, utilizing specialized storage containers and advanced feeding devices. Depending on specific applications, their design can range from sleek, compact constructions to highly adaptable modular concepts.


Principle
The operation of a loss-in-weight feeder revolves around a simple yet sophisticated principle: as material flows through the feeder, the system's overall weight diminishes. By meticulously controlling the loss-in-weight feeder, the feed rate is precisely adjusted to ensure that the speed of weight reduction aligns perfectly with the desired feed rate. The system continuously monitors the flow of material to maintain optimal performance.
During operation, a continuous weighing process is applied to all components and the materials they contain, including the feeder, the hopper, and the materials themselves.
Gravimetric feeders, for instance, may experience slight fluctuations in their feed rates due to changes in the filling capacity of the augers and variations in the material's bulk density. These discrepancies are expertly managed by adjusting the auger speed, ensuring a consistent and even product dispensation.

Features

1. Engineered with a cantilever-type weighing frame, our feeders boast a lower center of gravity and enhanced anti-interference qualities, ensuring reduced vibration and superior stability throughout operation.
2. The design features a vertical U-shaped hopper with a mirror-like inner wall and no corner enclosures, effectively preventing material bridging and ensuring smooth material flow.
3. Our stainless steel bellow sensor is renowned for its minimal deformation over extended use, offering high precision with negligible signal drift, and is built to endure even the harshest environments.
4. Utilizing 485 digital transmission, our system ensures weighing data is relayed without attenuation or interference, guaranteeing accurate and reliable performance.
5. The feeding and stirring processes are independently controlled, with a separate agitation motor, allowing for adjustable stirring speeds to match precise operational demands.
6. By eliminating the agitation motor from the top of the hopper, we achieve reduced operational vibration, leading to enhanced stability and pinpoint accuracy.

FAQs

1. How does the loss-in-weight feeder work? The loss-in-weight feeder operates on a precise mechanism: as the feeder discharges material, the system continuously weighs the feeder, hopper, and material. The rate of weight decrease is calculated, and the feeder speed is modulated to maintain the desired feed rate, ensuring optimal performance.

The gravimetric loss-in-weight feeder is an integral instrument designed to precisely regulate and measure the flow rate of substances within a system. This advanced equipment adeptly manages bulk solids, ensuring a steady discharge at a consistent weight per unit of time, either in kg/min or kg/hour. The weight signal serves as a crucial feedback control mechanism, overseeing and adjusting the feed rate within the instrument. Notable weighing systems include platform scales, load cells, and weigh hoppers. Depending on the end-to-end process requirements, the gravimetric feeder can operate as either a loss-in-weight or gain-in-weight system.
