Vibration and impact

Rotary vibration, linear vibration and intermittent impact.

Air-driven mechanisms move bulk material, assist discharge and compact material in vessels and equipment.

Scenario 01

How the vibrator generates motion

Rotating turbines, balls or rollers generate centrifugal force inside the housing. The mechanism and air supply determine the vibration frequency and force.

Product questions

01Rotary Pneumatic VibratorsHow do rotary vibration, linear vibration and impact differ?

Rotary vibrators generate circular vibration through a rotating mechanism. Piston vibrators move along one axis, while impact hammers deliver individual blows rather than continuous vibration.

02Rotary Pneumatic VibratorsDoes air pressure affect vibrator performance?

Yes. Supply pressure affects frequency, force and air consumption. Performance values apply at the stated pressure and are not directly interchangeable between pressure levels.

03Rotary Pneumatic VibratorsHow is vibration transmitted to the material?

The mounting transfers force into the hopper, chute, screen or container. Vessel stiffness, load and mounting position affect the resulting motion, so the vibrator and the supporting structure act together.
