DIY Guide: Testing Mineral's Hardness (Explained by Expert)

The Mohs hardness scale. It’s vital to understand that the Mohs scale is not a linear scale.Instead, it ranks minerals on a relative scale based on their scratch hardness, so although corundum (ruby or sapphire) is a 9, a diamond at 10 is almost 5 times harder (according to Vickers Absolute Hardness Scale) and 3 times harder (according to

What is the hardness capactiy of a cone crusher for

To determine the cone crusher hardness limit, one needs to understand two things: how hard a rock can be and how much energy is needed to break it. A cone crusher can only reduce rocks to very fine particles. The harder the rock, the finer the particle. Method 2: Use Indian Minerals Hardness Test. Method 3: Use Rockwell Cone
