Twin screw feeders for difficult bulk materials
For manufacturers handling sticky or fine powders, twin screw feeders ensure reliable flow and precise dosing, solving material bridging and feeding challenges in continuous operations.

Feeds and Conveys Bulk Materials Accurately
The K2-ML-T35 and other models from Coperion K-Tron are designed to provide precise feeding of bulk materials with twin screw technology. These feeders excel in handling challenging materials such as superabsorbent polymers, dairy protein powders, and powder coatings. They operate with a dual-screw mechanism tailored to both volumetric and gravimetric configurations, ensuring high accuracy in continuous and automated processing environments, critical for industries like plastics, chemicals, and pharmaceuticals.
The feeders use high accuracy SFT weighing technology to manage feed rates with precision, capable of modifying throughput to meet specific production demands. They are integrated seamlessly into existing processing lines, featuring modular designs that allow easy customization and flexibility. With the availability of hazardous location options (ATEX, NEC) and constructed with stainless steel for corrosion resistance, the feeders meet rigorous industry standards.
Designed for seamless integration, these feeders offer PLC controls for automated system management, which can significantly reduce labor costs and improve processing efficiency. Additionally, maintenance and cleaning are streamlined by easy disassembly features, ensuring compliance with sanitary requirements in food and pharmaceutical applications. For operations seeking reduced energy consumption, the feeders boast minimal energy use aligned with environmental standards, making them an efficient choice for modern manufacturing operations.
