The screw metering scale is a high-precision industrial device engineered for accurate measurement and controlled dispensing of bulk materials, including powders, granules, and small pellets. Its core functionality revolves around a rotating screw conveyor, which works in tandem with integrated weighing sensors and a smart control system to regulate material flow with exceptional precision.
Operating on the principle of volumetric and gravimetric integration, the scale utilizes the screw’s rotational speed and pitch to convey materials consistently. As the screw turns, it feeds material through a hopper and into the metering chamber, where load cells or weight sensors monitor the real-time mass flow. The control system dynamically adjusts the screw’s rotation speed based on preset parameters, ensuring the dispensed quantity aligns precisely with desired targets—minimizing waste and maintaining strict dosage consistency.
Designed for versatility, it adapts to various material properties, from free-flowing to slightly cohesive substances, and offers adjustable metering ranges to suit diverse production needs. Key features include robust construction (resistant to corrosion and wear), easy disassembly for cleaning, and seamless integration with automated production lines via PLC or HMI systems.
Widely applied in industries such as food processing, pharmaceuticals, chemicals, and building materials, the screw metering scale enhances production efficiency by enabling precise batching, continuous feeding, and reliable inventory control. Its ability to deliver repeatable accuracy (typically within ±1% to ±0.5%) makes it an essential component in quality-critical processes where consistent material dosing is paramount.
