Grinding media is used to crush, crumble, flatten and generally pulverize things in a mill. Typically made of small and textured parts, it’s essential for both the act of grinding and the preservation of your grinding mill, so you won’t want to cut corners with your selection. You’ll want to take your time and do it right.
But what if you aren’t sure how to choose grinding media for your mill? What do you need to know in advance? Here are just a few suggestions when it’s time to shop for grinding media.
1. Pick Your Material
Grinding media comes in many different varieties, so it’s up to you to decide which is best for your mill. Aluminum oxide is cheap but lower in quality than other materials; soda lime glass is more expensive but also more durable. Ceramic grinding media will help you produce a finer dust; dyed polyurethane will help you color-code your output. There’s no right or wrong answer when it comes to the type of material that you prefer, so do your research and make up your own mind.
2. Think About Shape
Grinding media is available in balls, cubes, cylinders, satellites and even sand. Their shape can have a big impact on the speed and safety of your mill, so it’s important that you choose carefully. How fast do you need to work? How strongly do you need to grind your materials? What kind of wear and tear will the grinding media have on your mill? These are all questions to ask before you make a final decision on shapes.
3. Create a Budget
Last but certainly not least, give yourself a price range when you go shopping for grinding media. This will keep you from overspending or getting distracted by shiny features that you don’t need. Keep in mind, too, that different websites might sell by different units, so an ounce of one material might be worth more than a pound of another. Stay vigilant if you want to get the best deal.
If you’re in the market for grinding materials, these are just a few things to consider as you shop. At the end of the day, the most important thing is that you’re confident in your purchase, so find a good brand that you can trust and buy something that leaves you feeling satisfied.
