force required to crush rocks

About this site

If the stone is softer, you can crush it with a force of 4200 tons or one fourth of the previous figures. Crushing rock by brute force is usually NOT done. A combination of impact and tension is more efficient, specially because most rocks are anisotropic.

About this site

Crushing a rock involves deforming it to the point that the grains break apart and that is a force x distance (I.e. Work) problem. whether it takes 5 seconds or a couple of minutes to get the job done will determine the power required (work/time) but time is irrelevant if you lack the ability to apply the needed force with your hand.

Lets say shattering is a mean particle size of 2 in or 5 cm. We can back into it which would be a powderfactor of 2.5kg/m 3 which means 2.5kg of blastex. We go back to the energy density of 740 cal/g, which converts to 3,096,160 joules / kg, since we have 2.5kg we need 7,740,400 joules of energy to shatter that 1 m 3 rock. 2.
