5 Aggregate Production
As with other compression crushers, the cone crusher yields a somewhat elongated and slivery particle shape. This may be minimized, however, by "choke" feeding the crusher. This technique will also make the shape and size more uniform. One way to choke feed is with a surge hopper and a controlled belt-feed to the cone crusher (Figure 5-10).
What You Need to Know About Building Trails with Crusher ...
Particle size for crusher fines on trails should be 3/8" minus. Fines from granite or other suitable hard stone works best.

This relates to two of the 10 points listed for cubical product shape, eg setting close to the desired product size and using the correct flow sheet.
Tips for maintaining efficiency in crushing circuits
· The settings on a jaw crusher are designed to produce material ideal for secondary crushing. The best particle shape is typically found in material about the same size as the CSS. Smaller sizes will contain a higher proportion of elongated particles because they have passed through the crusher without being touched.
Dual roll crushers, how they function
If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls.

What is the eccentric throw? — SRP
The eccentric throw is one of the most important parameters in defining the job that your cone crusher does. The mantle in a cone crusher spins in conical pendulum motion. That means it doesn’t stay in the center of the chamber – it sweeps around moving closer and further away from the concave. This is what creates the crushing action. At a given point on the concave, material is ...
