Introduction
Gravimetric Screw Feeder Is A Type Of Rotary Screw Feeder Running With A Greater Accuracy With Respect To Actual Loss In Weight Concept. Feeder Comes With A Plc Panel In Which The Rate Of Loss In Weight By Controlling The Speed Of The Rotary Screw Feeder Which Has Been Set According To The Process Requirement. Plc Panel Controlling Actions Are Carried Out Under PidActions To Maintain The Accuracy.
The Rate Of Loss In Weight Can Be Controlled By Various Methods.
A) By Manually Entering The Rate Of Loss In Weight.
B) By Entering A Ratio With Respective To Any Of Flow Achieved From Plant Side.

Features and Benefits
- A gravimetric feeder is a self-calibrating dosing system that doses based on weight in speed. A volumetric feeder, on the other hand, does this based on volume in speed. In gravimetric dosing, the weight of the dosed additive is measured using a load cell that is the foundation of the entire system. Weight is calculated using loss-in-weight technology, which measures the reduced weight while dosing.
- In the self-calibratingGravimetric feedersystem, the motor automatically alters its speed when a change is detected in the material flow. This eliminates the need for manual adjustment, which is required when using a volumetric feeder. Such a change in material flow can be the result of the addition of new material or fluctuations in the material density, among other factors. This means that, when using a gravimetric feeder to dose, you are in complete control of the quality of your final product. Thanks to the gravimetric feeder's self-calibrating dosing system, you will never run the risk of overdosing and will therefore automatically save costs when using expensive additives.
- In addition to the advantages offered by the self-calibrating technology, a gravimetric feeder provided from us is easy to operate using the touch screen controller.Gravimetric feedercan also be provided with optional monitoring and reporting software. This software allows for close monitoring of the production process for quality management purposes, and any errors in the production process are quickly discovered.
