GYRATORY CRUSHERS The original patent for the gyratory crusher was granted to Phile- tus W. Gates in 1881. This fint crusher was used by the Buffalo Cement Co. At the time these early gyratory crushers were developed all mining and quarrying, either underground or open pit, was done by hand; tonnages generally were small and product ...

Gyratory crushers may seem like complex machines, but their principle of operation is surprisingly straightforward. At its core, a gyratory crusher consists of a mantle that rotates within a concave bowl-shaped housing. As the mantle gyrates, it creates a crushing action by compressing the rock against the stationary concave walls. ...

A sectional view of the single-toggle type of jaw crusher is shown below. In one respect, the working principle and application of this machine are similar: the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point. The motion is, however, a more complex one than the …

A jaw crusher mainly works on the principle of reciprocating motion exhibited by the moveable jaw of the jaw crusher. The repeated movement of the jaws results in the development of compression force that further causes the breakdown of the rock or the ore placed between the two jaws into smaller pieces. The movement of the jaw crusher is ...

Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …
