What Type of Rock Tumbler Are There?

Rock tumblers are designed for anyone to enjoy, so whether you need one for your job, your own hobby, or for your kid who collects rocks, you will need to make sure that you choose the right type of rock tumbler. Most of the rock tumblers on the market are rotary. They give you a smooth finish; but if you want a quicker polish, then a vibratory tumbler may be an option. However, these will not give you a smooth finish like a rotary tumbler. Rock tumblers can typically be separated into three categories.

Toy Rock Tumblers: These rock tumblers are designed to smooth a small handful of stones at a time. The machines are made from plastic, so they may not be the most durable option, but they are they are the cheapest, which is why they are great for kids. The plastic material tends to wear quickly, and it also makes a lot of noise when the machine is tumbling.

Hobbyist Rock Tumblers: These are mid-tier rock tumblers that are designed to be a little more durable, so it has a metal barrel that can hold two to 10 pounds of rocks at once. The inside of the barrel is lined with rubber so that it does not create a lot of noise during the tumbling process. This type of tumbler can even be repaired, so it will last for years to come.

Commercial Rock Tumblers: These are large machines that are used for industrial purposes. They are able to tumble a few thousand pounds of rocks at once; so if you work for a company that creates smooth stones for a driveway, jewelry, or any other reason, you may need to use this type of tumbler.

Benefits of the Best Rock Tumbler

When you purchase a rock tumbler, you will find that there are many benefits to owning one. First, these devices are quick and easy to use, and the result is often a smooth round shape that shines.

In addition, you do not need to watch over these models are they are working, which means that you can go on about your day as you normally would.

Downsides of Rock Tumblers

As with any purchase that you make, there are going to be a few downsides to consider. Many rock tumblers take several days to produce smooth rock, so you may need to keep it running for more than a week.

Don’t forget that plastic models will wear out faster, so a metal barrel may be the best option when it comes to longevity.
