Driven by compressed air, the internal balls, rollers, pistons, or turbines generate high-frequency vibrations, which are used to prevent and eliminate material blockages, bridging, and adhesion in silos, pipelines, chutes, and other equipment.
A pneumatic vibrator is a pneumatic device that using high-speed rotating assembly to convert compressed air energy into mechanical vibration. It features a metal housing that protects internal components from the effects of vibration while improving material handling efficiency. Suitable for harsh environments, it can function as a complete pneumatic machine and is widely used in applications such as promoting material flow, preventing blockages, and assisting material feeding.
Overview of fokca turbine pneumatic vibrator
Drive method: Compressed air.
Types: Ball type, roller type, piston type, turbine type, etc.
Advantages: Simple structure, quick start, high-temperature resistance, explosion-proof (no electric spark), suitable for dusty or hazardous environments.
Disadvantages: Requires a stable air supply, relatively high air consumption.
Applications: Preventing blockages in silos, screening equipment, powder conveying pipelines, etc.
Food processing industry:It is an ideal for powdered or hygroscopic materials such as milk powder, flour, grains, sugar, coffee powder, etc.The stable high-frequency vibration prevents bridging and ensures smooth discharge from silos and hoppers.
Pneumatic concrete vibrator:This turbine vibrator can be used to eliminate air bubbles in concrete, enhancing its density, strength, and durability. In the production of precast components such as pipe piles and utility tunnels, long-axis vibrators or external vibrators are used to ensure internal compaction of large tubular components.
Pneumatic vibrating table:It can be used to compact materials or components placed on the table surface through vibration. For example, in concrete component plants, concrete mixtures are placed into molds and then subjected to intense vibration on the vibrating table to achieve rapid compaction and molding.
Pneumatic vibration isolation table and system:It can also be used to isolate or reduce the transmission of external vibrations to precision equipment or workbenches.
| Characteristics | turbine | piston | ball |
| Working Principle | Turbine rotation, centrifugal force | Piston reciprocation, impact force | Steel ball rotation, centrifugal force |
| Vibration Characteristics | High frequency, low amplitude, continuous | Low frequency, high amplitude, impact | High frequency, low amplitude, multi-directional |
| Noise Level | Relatively low | High | Medium |
| Maintenance Requirements | Requires lubrication | Usually lubrication-free | Basically maintenance-free |

Based on the comparative table above, it is not difficult to see that the turbine vibrator generates centrifugal force through high-speed rotation, producing high-frequency, low-amplitude continuous vibration. Its core advantages lie in gentle vibration and extremely low noise levels, making it particularly suitable for handling fine materials and applications requiring a quiet working environment. The main disadvantages are the necessity for continuous lubrication maintenance and its unsuitability for heavy-duty or severely compacted materials.
If you want to know the working principle of turbine vibrator,you must make it clear about the comonents of it.
Turbine Rotor: This is the "heart" of the entire device. It is essentially an impeller with an eccentric mass block. This mass is not uniformly distributed but is intentionally designed to be off-center.
Housing: This roller-type design generally features a robust metal chamber used to house the turbine rotor and is equipped with an air inlet and outlet.
Compressed Air Supply System: Provides a clean and dry power source.
Power Injection
Prepared compressed air is directed into the vibrator through the air inlet and precisely ejected onto the blades of the turbine rotor.
Turbine Rotation
The high-pressure airflow strikes the turbine blades, transferring the pressure and kinetic energy of the air to the turbine, driving it to rotate at high speed. The rotational speed is extremely high, typically reaching thousands to tens of thousands of revolutions per minute (RPM).
Centrifugal Force Generation
Due to the eccentric mass block on the turbine rotor, when it rotates at high speed, a powerful and continuously changing centrifugal force is generated. This force is the source of the vibration transmitted externally by the vibrator.
Vibration Generation
This high-speed, directionally changing centrifugal force is transmitted through the bearings to the entire housing of the vibrator. The housing then transfers this force to the connected equipment. Ultimately, this continuous, high-speed variation in centrifugal force manifests as the desired sustained, high-frequency mechanical vibration.
