Loss-in-weight K3 vibratory feeder
Loss-in-weight vibratory feeder for fragile materials
Gentle gravimetric feeder for food, pharma & industrial applications
Coperion K-Tron K3 vibratory Feeder is a high-precision gravimetric system engineered for gentle handling of fragile, friable, abrasive, or fibrous materials. Designed for applications requiring uniform, low-rate feeding, it delivers exceptional accuracy through its patented vibratory drive technology. The modular K3 range is available in standard and hygienic easy-clean versions, making it ideal for industries such as food, pharmaceutical, chemical, and plastics.
The K3 vibratory feeder is ideal for:
- Fragile materials: finished food ingredients, flakes, or fragile granules
- Abrasive or fibrous products: glass fibers, minerals, or tough additives
- Low-rate or uniform feed applications requiring gentle material discharge
- Hygienic or ATEX environments demanding precise, dust-free operation
Benefits:
- Gentle, low-impact feeding for delicate materials
- High accuracy with patented parallel-motion drive technology
- Modular tray design for easy customization
- Quick product changeover with special quick-release clamps
- Minimal maintenance, no mechanical wear parts
- Low energy consumption and reduced downtime
This feeder is compatible with plastics, chemicals, and mineral processing applications. For more details, please visit the Loss-in-weight K3 vibratory feeder page on Coperion performance material website.

Vibratory feeder line ensures precise, even discharge by maintaining consistent material flow with minimal pulsation. The innovative drive system uses a pendulum-based shock absorber to direct motion purely along the feeding axis, eliminating rotational movement common in traditional vibratory feeders. This ensures a smooth, controlled flow even at very low feed rates, protecting product integrity.
Designed for precision and reliability
Equipped with Coperion K-Tron’s advanced control system, the K3 continuously monitors acceleration, displacement, load, current, and temperature up to 25,000 times per second. The intelligent controller automatically fine-tunes vibration amplitude for optimal mass flow, ensuring steady and repeatable accuracy over time.
Built for hygienic and industrial use
The K3 series is available in standard and hygienic design (HD) versions, including silicone covers to fully enclose the drive assembly. This makes it suitable for food and pharmaceutical applications while maintaining compliance with ATEX and NEC safety standards. The absence of moving wear parts minimizes cleaning effort and lowers maintenance costs, supporting long-term operational efficiency.
