Considerations in Belt Feeder Design & Operation

Belt Speed. Conveyor belt speed, or the speed at which the belt passes under the hopper, also acts as a measure to control feed rate. By increasing belt speed, flow rate is also increased. Strike-off plate height and belt speed are adjusted in tandem to find the right balance between the desired flow rate and the amount of material the conveyor

Diagnosing Supplemental Restraint Systems (SRS) MOTOR

I’m sure the birthplace of automotive passenger restraints was the front seat of my dad’s ’57 Chevy. His right arm would “deploy” every time he slammed the brakes, pinning me into that seat with the force of a five-point racing harness. Dad’s arm has since been replaced by a supplemental restraint system (SRS) consisting of
