Libra Mass Flow System

The Libra VF Mass Flow System is a two-tier conveyor that combines VF vibratory technology with load-cell scales, so product is measured by both weight and volume. Its loss-in-weight feedback gives continuous, real-time load measurement and adjusts product speed to keep feed rates consistent and precise. Achievable accuracy is ±1%, which outperforms conventional weigh belts and weigh chutes.

Installation and hygiene

The Libra has a small footprint and close to 100% vibration isolation efficiency, so it can be mounted on many existing sub-structures and used to meter, weigh, blend and feed conveyors, drum seasoners and more. There are no pulleys to break or collect debris and no belts to maintain or clean, and product contact surfaces are FDA-approved stainless steel.

Typical applications

• Product blending
• Metering
• Drum feeding
• Weighing

The VF line

PPM's VF electromagnetic conveyors have been used in food plants for more than 30 years. One drive concept serves a wide range of products, from snacks, nuts, baked goods, dried fruit and cereals to frozen and wet products.
