The belt scale weigh frame is suitable for medium to heavy capacity belt conveyors, for high accuracy continuous weighing applications. The special free-floating structure and the multiple idler technology allows to obtain very high performances. All the scales are custom made.

Main advantages

• For high capacities, up to 20.000 t/h
• Customized dimensions for any conveyor width, from 500 to 3000 mm.
• Very accurate: from 0,25 % of accuracy (*), MID approved
• Suitable for inclined belts up to 25 degrees(*), thanks to its special technology.

Weigh frame technical features
