I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged. Both of these …

Therefore, work is equal to force multiplied by distance: W=Fd W = F d. Because force is a component of work and an impact is the conversion of energy into work, you can use the equations for energy and work to solve for the force of an impact. The distance traveled when the work is accomplished by an impact is called the stop distance.

For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.

A jaw crusher (see Fig. 2) is a comminution device designed to impart an impact on a rock particle placed between a fixed and a moving plate (jaw). The faces of the plates are made of hardened steel. Both plates could be flat or convex. The moving plate applies the force of impact on the particles held against the stationary plate.

You can either use collision distance or collision time to calculate impact energy and force. Let's estimate the impact force on a golf ball impacting at 5 m/s with a collision distance of 0.5 m. To find the impact energy: Select collision distance as calculation parameter. m = 45.9~mat {g} m = 45.9 g.
