Ro-Tap Sieve Shakers

The W.S. Tyler RO-TAP® has been used for decades and can be traced to dozens of industry standards. Its durable qualities are available in both mechanical and electromagnetic models, making applicable to countless particle analysis operations. 

At this point, you probably know what a RO-TAP is, how much it costs, as well as the pro and cons associated with using this particular unit. That said, you’re also probably wondering what comes with an RO-TAP purchase.RO-TAP-Sieve-Shaker

W.S. Tyler has been a pioneer of test sieve analysis since the 1930s and knows exactly what it takes to ensure your sieve shaker equipment yields accurate results for decades. 

With that, this article will take a deep dive into what the buying process of a RO-TAP looks like, how to request a quote, what you can expect when your RO-TAP arrives at your facility, how to set it up, what warranty options, and what you should do in the event that you need technical assistance.

What Comes With a RO-TAP Purchase?

Other than test sieves, everything you need to get your RO-TAP unit up and running is included. You will receive two boxes when your delivery arrives and can expect: 

Main Box: 

  • The RO-TAP model you selected

Secondary Box:

  • Sieve stack cover with the cork pre-installed
  • Manual
  • Sieve adjustment inserts (RX-812 ONLY)

When purchasing a RO-TAP unit, you also have the option to add a sound enclosure or a test stand to your order. While these accessories are both sold separately, customers who bundle them with an RX-29 unit will receive a 10% discount on each item in the order.


What Initial Setup is Required?

Initial setup begins with taking the RO-TAP unit itself out of the box in which it was shipped in. As the average weight range of an RO-TAP is from 90 to 180 LBS depending on which model you select, we highly recommend that you have a co-worker assist you.

If you are using an RX-29, RX-30, or an RX-94 model, you will need to check the hammer height to ensure it complies with the number of sieves in your stack. If hammer adjustment is required, you simply use a T-Square to ensure the height of the hammer is 1 5/16”.

Once this is complete, all there is left to do is to load a sieve stack into the RO-TAP, place the sieve cover on top of the stack, plug it in, power it on, and begin yielding accurate results.

To learn more about conducting a particle size analysis from beginning to end, refer to our article: How to perform a test sieve analysis.

When incorporating any of the RO-TAP models into a lab setting, it is vital that you attach it to a table that is sturdy enough to withstand both the weight and oscillating motion of the unit. You must also make sure you order the correct electrical configuration for the outlets in your facility.

What Warranty Options are Available?

Each RO-TAP unit comes with a 1-year guaranteed warranty that starts once the unit is powered on for the first time. Under the warranty, any manufacturing malfunctions will be fixed at no charge within the year time frame.

After the first year, it is up to the on-site team to maintain a regular maintenance schedule to avoid issues, such as unusually loud equipment. Placing oil on some of the bushings and checking the moving parts every few months are simple maintenance techniques that will keep your operation up and running.RO-TAP-Maintenance-Kit

With that, we recommend you keep at least one maintenance kit on hand to minimize any downtime you may encounter after the warranty has expired.
