How much force does it take to crush a watermelon?
When it comes to determining the force required to crush a watermelon, there are several factors to consider. The size and ripeness of the watermelon, the method of crushing, and the force applied all play a role in determining the amount of force needed. This can be an interesting topic to explore, as there are many variables that can affect ...
Optimal energy management for a jaw crushing process in deep mines
This paper develops two optimal control models for the energy management of a mining crushing process based on jaw crushers. The performance index for both models is defined as the energy cost to ...
Crushing Resistance
The crushing resistance of SSA can provide an indication of its strength as an aggregate component and has been assessed, though only to a limited extent, using the 10% fines test, which measures the force needed to crush the material to the extent that 10% of the particles pass the 0.063-mm sieve, though this procedure is not strictly ...

Jaw Crushers
The overarching principle guiding jaw crushers is a compression action. A V-shaped alignment houses the fixed jaw, serving as the immovable surface that facilitates the initial breakage. Simultaneously, the movable jaw, in a swinging motion, exerts force on the incoming material, compelling it against the unyielding surface of the fixed jaw.
