Mass Finishing Process Water, Part 1 – Understand When to Balance Flow or Flood the Process Bowl

Maintaining the correct compound and water flow rate into a mass finishing machine is essential for the stability and success of a process.

If inadequate compound and water are supplied to the machine, results will be more extreme and lead to unpredictable processing times, ineffective finishing, dirty work pieces after finishing, glazed media, and, potentially, a total collapse of the process.

Excessive compound and water flow can be equally problematic. Too much water and compound will slow down the movement of media and work pieces in the machine or cause a complete stop.

For example, in rotary vibrators the typical spiral movement of the media/work piece mix will give way to an uncontrolled shaking. In centrifugal disc machines, the rotating spinner will slip under the media/work piece mix with no movement at all.

Longer processing times, poor finishing results, and even a complete collapse of the process can occur.

For the best results and stability, Rosler understands that the flow rate of compound and water into the machine must be equal to the flow rate out of the machine.

Mass Finishing Water & Compounds, Part 2 – Precise Water Flow, Dosing Drive Results

A number of factors contribute to mass finishing success. Machinery, consumables, compounds, and process water must be evaluated individually and as a whole to create optimal results and stable process conditions.

When considering the flow rate of compound and process water into the processing bowl of a mass finishing machine, careful calibration is required based on the machine type and size, finishing task, condition of the raw work pieces, and process water conditions.

For example, high‐energy machines require a much higher flow rate than vibratory finishing systems. Similarly, work pieces heavily contaminated with oil, grease, and/or dirt require more compound and water than less contaminated work pieces.

Water flow and compound dosing rates are usually determined by processing trials in the test lab of the equipment supplier. Once a finishing process has been defined, the user must make sure that the established water and compound flow parameters are precisely maintained. This requires a well-calibrated and well-maintained dosing system.

At Rosler, we draw upon more than 80 years of worldwide experience to create and maintain effective mass finishing systems and deliver precise results. Our ability to do so is thanks, in part, to understanding the importance of water flow and compound dosing.

Mass Finishing Success Requires Constant Operational Focus

When most companies take on capital expenditure projects such as purchasing mass finishing equipment, very careful attention is paid to investing in the most productive, cost‐efficient equipment as possible to achieve the best possible quality. Operational efficiency is often another story.

Once the equipment is up and running routine takes over and less attention is paid to keeping the equipment operating at its peak performance. Whether the machinery is never calibrated to reach its fullest potential or the on-going process is not carefully monitored once the process is dialed in, lacking operational focus can be costly and counterproductive. Figuratively speaking, poorly managed mass finishing operations are pouring money down the drain!

Rosler works with its clients to ensure that our machinery delivers initial success and continues to provide precise, repeatable results long into the future by promoting operational attention and heading off costly mistakes.

Consequences of Inattention

For mass finishing processes, the lack of operational focus may take many forms individually or simultaneously, including:
