Did you know? The efficiency of the same stone crusher machine can vary drastically when crushing granite compared to limestone – this hides the secret of material "brittleness."
Brittleness is a direct indicator of the difficulty of material crushing, and it is deeply linked to properties such as strength and hardness: materials with high strength "resist splitting," and materials with high hardness "resist grinding." For example, high-hardness glass is not difficult to break, but it is very difficult to grind into fine powder. Small-particle materials, due to fewer cracks, have higher strength than large-particle materials, making them more difficult to crush.
In practical operation, people often use the "Proctor hardness coefficient" to "rank" the hardness of materials; the higher the coefficient, the stronger the material. The "combat power" of a stone crusher machine is designed around these properties: dealing with high-strength materials requires increased impact force, while processing high-hardness materials requires strengthening the grinding structure.
From ore to construction waste, understanding the "strength code" of materials allows stone crusher machines to find the optimal balance between efficiency and energy consumption.
