formula for crushing impact force of rotating hammer:

Impact Force - Engineering ToolBox

F weight = force due to gravity - or weight (N, lb f) a g = acceleration of gravity (9.81 m/s 2, 32.17405 ft/s 2) h = falling height (m) If the dynamic energy from the fall is converted to impact work - equation 2 and 4 can be combined to. F avg s = m a g h (5) The impact force

Impact Force Calculator - calculate the impact force in a ...

The above equation can be used to calculate both impact force of a falling ojbect as well as impact force of a horizontally-moving object such as in a car crash or plane crash. The formula can easily be extended to calculate the approximate maximum impact force (a.k.a. peak impact force) by multiplying the resulting average impact force by two.

How to Calculate Force of Impact Sciencing

During an impact, the energy of a moving object is converted into work, and force plays an important role. To create an equation for the force of any impact, you can set the equations for energy and work equal to each other and solve for force. From there, calculating the force of an impact is relatively easy.

Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
