Hammer Crusher Empirical Formula For Capacity Calculation

Estimation of maximum crushing capacity of

An empirical equation to estimate the maximum crushing capacity of hammer mills was obtained. The maximum crushing capacity measured was on an average about 1.5 times larger than the value calculated from the empirical equation. However, the approximate estimation of the maximum crushing capacity of hammer mills was possible.

How to Estimate the Load Capacity of Piles?

where W is the weight of the hammer, h is the height of fall of the hammer in cm, % is the efficiency of the hammer, S is the set or penetration of the pile per blow, usually taken as the average penetration of the pile for the last 5-10 blows, C is the empirical constant to account for reduction in theoretical set due to energy loss, that is, 2.5 cm for drop hammer and 0.25 cm for stream hammer.
