512 impact crushers breakage is achieved by impact using either hammer action on the individual particles or by sudden impact from a high velocity trajectory high reduction ratios of between 201 and 401 can be achieved with hammer type impact crushers only low reduction ratios of about 21 can be achieved with kinetic energy type impact.
Another approach to determine the expected impact force is to estimate the pulse width of the expected forcetime curve we can use the pulse width and employ newton’s 2nd law of motion fma to calculate the expected impact force using the final velocity calculated from the conversation of
