Recirculation of vibratory finishing water without filter aids

Recirculation of Vibratory Finishing Water without Filter Aids

During the vibratory finishing of workpieces, extremely fine metal particles and abrasion from media are generated. These particles enter the process water and gradually increase the load on the entire system.

To ensure a stable production process and consistently high machining quality, reliable cleaning of the process water is essential. At the same time, maintenance effort, consumables, and disposal costs should be minimized.

Problem

During the vibratory finishing process, solid particles and abrasive residues continuously enter the process water. Without proper treatment, this can lead to:

• Deterioration of surface quality of the workpieces
• Deposits in tanks, pipelines and equipment
• Increased maintenance effort for machines
• Reduced service life of the process water
• Rising disposal and operating costs

Conventional filtration systems often require filter aids or consumables that must be regularly replaced and disposed of.

Solution

A centrifugal separator is used for continuous cleaning of the process water. The contaminated water is fed into the separator, where even the finest particles are reliably removed by high centrifugal forces.

The separated solids are discharged as compact sludge, while the cleaned water is returned to the production cycle. This method allows continuous recirculation of the process water—without the need for filter aids.

Centrifugal separators utilize the physical principle of phase separation in a centrifugal field and can efficiently remove even very fine particles from process fluids.

Advantages of Recirculation

• Continuously clean process water
• Stable machining conditions
• Reduced maintenance effort
• Extended service life of the fluid
• No filter consumables required
• Reduced disposal and operating costs

Continuous recirculation without filter aids improves efficiency and significantly reduces resource consumption.
