measurements Good way to compute the force of a .

To make the measurement of impact time repeatable you could make the hammer part of a second pendulum that hits the ball from different heights: you can then plot the relationship between impact velocity and impact time, and this will allow you to get the time when you hit the ball really hard (when you might not get a good repeatable measurement of the time or velocity).

Cone Crushers | McLanahan

A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the ...
