Improving jaw crusher safety | Hub-4
Rock enters the jaw crusher from the top of the machine and gets compressed between two surfaces — the fixed and moveable jaw. The rock will continue to be crushed until it is small enough to fall through the opening. Ensuring that the size of raw material is appropriately matched to the jaw opening, can alleviate blockage incidents.

Choke Feeding a Jaw Crusher | What is Choke Feed Looks Like
A crusher is choke fed when the chamber is full and there is material above to keep it full. This contrasts with regulated feed, where the flow of material to the crusher is throttled in some manner so that the crusher is never completely filled. Aa particle moves from level to level it drops a greater distance with each movement of the mantle.

The jaw crusher reduces the size of large rocks by dropping them into a "V"-shaped mouth at the top of the crusher chamber. This is created between one fixed rigid jaw and a pivoting swing jaw set at acute angles to each other. Compression is created by forcing the rock against the stationary plate in the crushing chamber as shown in Fig. 13.9.

Crusher - Wikipedia
A cone crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear-resistant mantle, and the enclosing concave hopper, covered by a manganese concave or a bowl liner. As rock enters the top of the cone crusher, it becomes wedged and squeezed between the mantle and the bowl liner or concave.
