Circulation water system

Saving in Resources by Using Closed-Loop Systems

Rösler Process water recycling systems can be connected to virtually any mass finishing machine. This increases the savings potential of mass finishing. Most mass finishing processes such as de-burring, precision grinding, rough grinding, radiussing or polishing are wet processes. Water and cleaning agents (compounds) are the carriers for resultant removal of media and metal fines.
The resultant process water is completely recycled via a closed-loop system. Water and compound savings contribute to significant cost reductions. The system technology is based on special centrifugal technology with an acceleration factor of up to 2000 g, coupled with environmentally-friendly chemistry developed in-house.
Rösler Process-water circulation systems can be adapted to any mass finishing application. Semi- and fully-automatic centrifugal systems are available.

Semi-automatic compact centrifuges Z800

In addition to exceptional separation performance, this series of semi-automatic basket centrifuges is particularly characterized by its space-saving placement in the immediate vicinity of the vibratory grinding machines. The centrifuge as well as the system control and the process water and clean water tank are functionally installed as a complete unit. The core of the installation is the centrifuge, developed and built by Rösler.

Automatic centrifuges Z1000

In some application cases, it is necessary to centrifuge particularly large quantities of solids or large volumes of water in a short period of time. Installations that provide for manually changing the slurry inserts often cannot be integrated into such a workflow. For this reason, process water circuit installations from the ASS series, with automatic slurry removal, are used here. The special feature of the automatic process water circuit installations is the automatic removal of solid particles after centrifuging into a 300-liter slurry carriage under the centrifuge. After this process, the rotor is rinsed in order to remove any possible residual contamination and to prevent imbalance and consequential short-term bearing wear in the following cleaning cycle. For safeguarding, the centrifuges are standard-equipped with an imbalance monitor that shuts off the system as required.


It is time to drive digital transformation forward and think of innovative digitalisation solutions for the vibratory finishing sector.

The patent-pending software developed by Rosler allows you to enter up to 13 different process parameters, such as compound concentration, pH value, conductivity or bacterial infestation, and to monitor them at the same time through the interactive interface. All relevant machine and process data is displayed on a dashboard. If a parameter is out of the target range and process problems occur the system makes recommendations for corrective actions that can be implemented immediately.. You can thus detect deviations from the setpoint values at an early stage and take immediate countermeasures. In addition, you have the option to review the history for all parameters in table or graph form and spot longer term trends in the process. in the long term by means of a history and displaying them in the form of diagrams or tables.

The smart process water management solution is the starting point for a series of upcoming digital developments. For example, automated measurements of process parameters and the adjustment of these parameters are future enhancements currently under development.
