Pros and Cons of a Ro-Tap Sieve Shaker
Deciding to buy particle analysis equipment can be an overwhelming process. There are a lot of different particle analysis machines and systems out there that all have unique pros and cons.
We want to help you during this decision making process by breaking down those pros and cons for one of our products, the Ro-Tap Sieve Shaker.
In this article, we are going to take a look at the pros and cons of a Ro-Tap Sieve Shaker.
We can’t speak for all sieve shakers with this list, but we think it’s safe to assume that some of these will be true for other brands of shakers as well, not just the Ro-Tap.
We offer both mechanical and electronic units of the Ro-Tap, as well as many different models of each of those. For the sake of this article, we are just going to be talking about our most popular machine, the Ro-Tap RX-29 and RX-30.
This is a mechanical shaker that is used to separate particles in a test sieve stack in industries all over the world.
We like to be upfront with our customers. While we think the Ro-Tap is a great solution for our customers, we also know that is isn’t right for everyone. We want to save you time in your buying process by addressing the pros and cons of our Ro-Tap Sieve Shaker.
The machine is built in our facility in Mentor, Ohio by our specialist. The machine was created to operate with two strong motions, oscillation(rotating) and a tapping motion.
Ro-Tap’s have a very long lifespan. We have customers who have had their sieve shakers for over 40 years. These are mechanical and robust machines that are designed to withstand a lot of movement and wear.
There are a few reasons we have listed cost as a proof the Ro-Tap Sieve Shaker. The first is that price is reasonable in terms of the unit itself.
A Ro-Tap Sieve Shaker is going to cost you anywhere from $1,230 to $3,902.
When looking at all types of particle analysis equipment, a Ro-Tap falls on the lower end of the cost range. Ro-Taps are less expensive than buying the more complex methods of particle analysis, like a computer particle analyzer. You could expect to pay at least $60,000 for one of those.
We have written an entire article on the cost of the Ro-Tap and all the options included. You can read all about it in: How Much Does a Ro-Tap Sieve Shaker Cost.
A second reason, which goes along with durability, is that for the price, this machine has a very long lifespan. We already addressed above how this machine can last a very long time, and it’s not super expensive either.
It may seem like a no-brainer, but the most obvious benefit of using a Ro-Tap is that you are eliminating the need to perform a hand sieve analysis.
The machine shakes the particles down through a test sieve stack and the results are analyzed at each sieve level. Because the machine is doing the manual work, this creates repeatable results each time. When you are doing a hand sieve analysis, there is a possibility for human error, and a sieve shaker eliminates that.
There can still be errors that occur in your process depending on your particle size and material being sieved. To ensure that you are using your sieve shaker properly and for the correct amount of time, you will need to perform an end of sieve analysis. This will ensure that you have consistent/repeatable results.
Using a sieve shaker decreases the time it takes to perform a sieve analysis. This allows you to not only perform and analyze results faster, but also allows you to complete more tests each day.
Sieving by hand requires more time and more diligence in your process to ensure accurate results.
This one is something we address often when we talk about the Ro-Tap. The Ro-Tap is noisy. The machine uses a hammer to tap particles down through a stack of test sieves while it oscillates and shakes. This tapping motion creates quite a bit of noise.
Some people find that the noise of the machine is too loud. We find this to be the case in small labs or situations where the machine runs nearby others working.
We wrote an article all about the noises the sieve shaker makes: 5 Reasons Your Sieve Shaker Is Noisy.
Once a sieve shaker has been used for about a year, it will start to need upkeep. There are a lot of parts inside of the machine and over time, they will suffer wear and tear.
Although replacing the parts is not usually difficult, it does require some downtime and some understanding of the machine. We offer diagrams and our customer service team for support.
It isn’t a massive amount of maintenance, but as opposed to a more advanced machine like the CPA, there is going to be more downtime.
The Ro-Tap Sieve shaker measures 28”w by 21"d by_25”h and weighs 170 lbs. It is not a small machine.
The sound enclosure cabinet measures 35"w by 24"d by 29"h.
We find this to be fine for most customers and labs. But, if you are operating in a very small space or need to move this machine frequently, you may find this to be a con of the machine.
If this sounds like you, we recommend one of our electronic Ro-Tap sieve shakers.
To Sum It Up
There are a lot of different options out there for you to pick from if you are thinking about particle analysis equipment.
