Loss-in-Weight Auger systems provide a reliable and efficient solution for controlling product discharge in various industries. Here’s a breakdown of how they work:
Applications:
- Product Discharge Monitoring: The system measures the amount of product lost from a hopper over a specified time period, offering precise control over discharge rates.
- Dual Screw Configuration: The system typically uses two screws – a feeding screw and a conveying screw – to move the product. The pre-feeder can be customized depending on the material and desired consistency, with options like rotary valves, belt conveyors, or chain conveyors.
- Closed System for Contamination Prevention: Since the product is never exposed to the atmosphere, the system reduces the risk of contamination by liquids or foreign bodies, ensuring a clean and dust-free environment.
- Variable Speed Control: The Loss-in-Weight Auger systems are equipped with variable speed controls. The weight throughput is directly proportional to the screw RPM or belt speed. This allows for flexibility in adjusting the discharge rate based on the desired weight or material consistency.
- Bulk Density Monitoring: The system monitors fluctuations in bulk density, which can affect weight consistency. The integrated scales detect these variations, and the PLC adjusts the speed accordingly to maintain accurate weight output.
- High Accuracy: Once the desired weight is input, the system will consistently maintain it, ensuring accuracy up to +/- 2%. This precise control is crucial for industries where precise dosing is needed.
