Centrifuge technology offers eco-friendly advantages

The mass finishing process creates waste water. This substance known as effluent must be properly processed for reuse or disposal. Centrifuge technology offers solutions for cleaning and/or recycling effluent.

Rosler offers a variety of options to process waste water including flocculation systems and the elimination of vibratory finishing sludge. Each type of waste has unique factors and considerations.

Mass Finishing 101

Often overlooked in the manufacturing process, mass finishing can help add value in a variety of ways.  Mass finishing can reduce or eliminate manual process steps, improve process consistency, increase throughput, reduce manual labor, and more.

Manufacturing or process engineers in a manufacturing plant do not have to be the expert that knows all the latest details and techniques of the finishing process. They do, however, need to have a good understanding of the basic mass finishing processes that can be applied.

Mass finishing describes a surface finishing method where parts are deburred, smoothed, polished, or cleaned using media (tumbling or vibratory), compounds (finishing soap), and specialized equipment.

Examples of mass finishing equipment include:

Understanding how the different process components, i.e. the machine, media, compound, water, and the incoming part all interact and influence the desired part finish is important. Each of the inputs in itself has a multitude of adjustments and parameters.

Centrifuge Technology Processes Effluent for Reuse and Disposal

In order to achieve the lowest total cost of ownership and the greatest process efficiency, recycling process water used in mass finishing processes is key. Reusing water not only reduces costs in the form of less consumables used, but also enables companies to reduce their discharge and disposal fees by replacing process water less often and complying with water and waste regulations.pollutant table

Waste water from mass finishing applications is often referred to as effluent and must be cleaned for recycling or discharge.

Waste Water Recycling – Centrifuge Technology Offers Cost, Environmental Savings

Mass finishing techniques are often used to uniformly prepare and finish work-pieces, but the compounds and liquids used to remove fines and other debris from work-pieces must be dealt with to ensure a repeatable process application. Cleaning and/or recycling waste water produced in the mass finishing process is easily achieved with centrifuge technology and provides opportunities to be more environmentally responsible and save money in the form of reduced labor and materials (cleaning agents and compounds).

How Centrifuges Work

In a centrifuge, waste materials including media and metal fines are often referred to as effluent. The effluent to be cleaned either flows directly from the mass finishing system Continue reading Waste Water Recycling – Centrifuge Technology Offers Cost, Environmental Savings

8 Considerations When Purchasing a Rotary Vibratory Machine

Buying Mass Finishing equipment, as with all investments, can be a bit overwhelming at first.   There will surely be a number of suppliers and machine types available to you.  In order to ensure you get the best value for your money we recommend you consider the following when purchasing a rotary vibratory machine:

Movement– Appearances can be deceiving, don’t be fooled into thinking all machines are the same just because the look similar.  Always test the machine and its processing ability before you buy!  Test its amplitude, see how regular the movement is, is it consistently driving the same way?

Strength and durability – Check how heavy the machine is, usually you’ll find something costs less because it is made of cheaper and lighter materials.

THE 9 MOST COMMON MISTAKES YOU NEED TO AVOID TO GET THE MOST OUT OF YOUR MASS FINISHING MACHINE

When maintained properly, mass finishing equipment can be very user friendly.

As a result sometimes operators can get into the habit of just turning them on each day and ignoring simple operating and maintenance rules.  Avoiding the following 9 mistakes that operators commonly make will help you get the most from your equipment:

  • They let the media level drop, often with the aim of saving money or so they can get more work pieces in. This changes the ratio of work pieces per media though and can affect process times, unloading ability, can cause components to damage each other, and can result in the required finish not being achievable.

New Vibratory System Design Accommodates Complex Shapes

Vibratory finishing systems are best known for treating large volumes of mass produced parts. However, thanks to a variety of new, innovative equipment designs, they are increasingly utilized for finishing single work pieces with highly complex geometries.

An excellent example of this new equipment design is Rosler’s model R150/2 DL. A rotary vibrator without an inner dome, this unique finishing process allows for work pieces to be bolted to the vibratory processing bowl.
