A screw feeder is a precise dosing device that is primarily used in the industrial processing of bulk materials. Its special design makes it ideal for the continuous and uniform dosing of powdery, fine-grained or free-flowing materials. Typical areas of application include plastics processing, the chemical, construction and food industries as well as other sectors in which precise quantity control is required.
The dosing principle of a screw feeder is based on a rotating screw conveyor that removes the material from a container and feeds it to the next process stage in a controlled manner. Depending on the application, screw feeders can work volumetrically or gravimetrically. Volumetric models dispense according to a set volume per revolution, while gravimetric systems monitor the actual weight in real time and regulate accordingly to ensure maximum dosing accuracy.
A key feature of the loss-in-weight feeder is its ability to take very accurate measurements. This is achieved by using high-precision sensors that can detect even the smallest changes in weight. This accuracy is particularly important in processes where compliance with precise recipes or formulations is required.
Another important aspect of the loss-in-weight feeder is its ability to integrate into automated systems. Many of these scales can be connected to control systems that automatically adjust the material flow based on the measured weights.
This enables very efficient and precise control of the dosing process.
In summary, a loss-in-weight feeder is a high-precision instrument used in various industries for the accurate dosing and weight measurement of materials. Its ability to measure and control continuous material flows makes it an indispensable tool in many modern manufacturing processes.
