A conveyor at 30 degrees has a cosine = 0.866. Therefore, a weight of 40 pounds on the conveyor would result in a measured force of 34.64 lbs on the scale. A fixed angle conveyor scale can be compensated by a change of gain in the scale. In the above example, 34.64 lbs/cos. (30)=40 pounds.

A weigh feeder can be dangerous. A pinch point exists between the slider deck and pulleys and the conveyor belt. ALWAYS STOP the belt, lock-out, and/or place a "Do Not Energize" tag on the main disconnect. It takes very little additional time to secure the weigh feeder. In particular, follow this safe practice when: • Replacing the belt,

Factors to Consider in Belt Feeder Design. Several factors influence belt feeder operation and reliability: Head Load. Head load is the single most important factor in belt feeder design. The head load is the amount of pressure put on the belt directly under the hopper opening as a result of the weight of the material resting on the belt.
