Do you know how to measure the "power" of a Stone Crusher Machine in grinding materials? The key indicator is the grinding ratio.

Divide the particle size D before grinding by the particle size d after grinding. The result, D/d, is the grinding ratio, representing the factor by which the particle size is reduced. For example, if a Stone Crusher Machine grinds ore from 10 cm to 1 cm, the grinding ratio is 10.

However, there are "nominal" and "average" grinding ratios: The nominal grinding ratio is the ratio of the maximum feed opening width to the discharge opening width of the Stone Crusher Machine, while the actual average grinding ratio is often larger. This is something to keep in mind when choosing a Stone Crusher Machine. It's also one of the economic indicators for Stone Crusher Machines: machines with a larger grinding ratio are generally more efficient, but this must be considered in conjunction with the unit power consumption (energy consumption per unit weight of material ground) to determine if it's truly cost-effective.

The grinding ratio of a Stone Crusher Machine holds the "efficiency code" for its work.
