The aim of this manual is to help engineers design balanced vibrating conveyors. They are used to transport bulk materials through stainless steel vibrating chutes for use in the food, chemical, pharmaceutical, tobacco and other industries. The equipment is considered hygienic to avoid contamination and is easy to clean. The conveyor belt is supported by elastic fibreglass springs fixed to a base. The vibration is produced by an eccentric driven by an electric motor. Below the chute is a steel profile frame with elastic springs fixed to the base with reverse vibrations of the chute. The weight of the chute must be equal to the weight of the counterweight. A vibrating conveyor in operation is balanced when the springs of the chute and counterweight are vibrating at their natural frequency, coinciding with or as close as possible to the rotation of the eccentric. This results in minimal vibration at the base, quiet operation and minimal maintenance.
