Piston vibrator linear, type BLE

Piston vibrator linear of the BLE series – Pneumatically driven, this serves to support material flow, screening, compacting, sorting, loosening, conveying and cleaning with the aid of vibration.

The piston vibrator is suitable for applications with special emphasis on an exactly linear direction of the force. The vibrators are available in various structural designs: cylindrical, 6 – corner (BLE8 only) and cuboid (BLE18 only).

They have a piston emerging from the housing, on which there are fastening possibilities. This type of piston vibrator can therefore be used, for example, as a vibratory drive for small conveyor troughs or similar installations.

Alternatively, our piston vibrators type K can be used, which have a closed housing with a completely encapsulated and internal piston.

Technical features

• Maintenance-free
• Frequency and amplitude adjustable
• Large vibration amplitudes
• Optimal start-stop behavior
• Start in any position
• Minimal noise emission
• Low air consumption

Field of application

These vibrators are suitable for the following applications:

• Vibratory drive for small discharge chutes or conveyor troughs
• Knocking off adhesions on the walls of bunkers, hoppers, containers and silos
• Drive for small vibrating tables and chutes
• Discharge aid for bins
• Maintaining material flow and clearing product jams

Vibration

Vibration is generated by means of a self-reversing piston guided in a cylinder.

This piston is blown with compressed air, which causes it to move linearly in the cylinder guide towards the end position. The direction of movement is reversed in the end position by the self-reversing action and the piston moves in the direction of the other end position. In this position, the direction of movement is also reversed. The inertia of the mass of the piston causes a force effect. This force effect is transmitted to the structure as a vibration (due to the continuous reversal).

The piston vibrators generate a linear and sinusoidal vibration due to this active principle.

Pressure/temperature

The piston vibrators are operated with up to 6 bar of compressed air. The frequency of the vibration can be increased/decreased by throttling the air supply.

The standard operating temperature is -10°C to +150°C (for model F15P only 0°C to +100°C).
