Quick Answer
Choose stone mill burrs for dry grains like wheat, and steel burrs for oily grains like corn or oily seeds, considering factors like durability, maintenance, and grain type.
Burr Material Considerations
When selecting between stone and steel mill burrs, consider the type of grain you plan to mill. Stone burrs are ideal for dry grains like wheat, oats, and rice, and are often preferred for their ability to produce a smooth, fine flour. In contrast, steel burrs are better suited for oily grains like corn, soybeans, and oily seeds, as they can handle the higher oil content without clogging.
Burr Durability and Maintenance
Stone burrs are generally more durable and require less maintenance than steel burrs. They can last for up to 5 years or more with proper care, while steel burrs typically need to be replaced every 1-2 years. However, steel burrs are often easier to clean and maintain, especially if you’re milling a variety of grains.
Practical Considerations
When choosing between stone and steel burrs, also consider factors like cost, space, and personal preference. Stone burrs tend to be more expensive upfront, but can be a cost-effective option in the long run. Steel burrs, on the other hand, are often more affordable, but may require more frequent replacement. Consider the specific needs of your grain mill and choose the burr material that best suits your requirements.
