This is because the Blake Jaw Crusher integrated a key mechanical principle – the toggle linkage – a concept students of mechanics are familiar with. ... Additionally, gyratory crushers have a higher crushing ratio (meaning that they can crush large material into smaller pieces), a larger feed opening, and a more consistent product size and ...
The crushing ratio of a jaw crusher results from the maximum achievable final fineness in relation to the maximum feed size. For Retsch jaw crushers, this lies between 26 and 220. A high value reflects the capacity of a jaw crusher to accept large sample pieces and provide powerful crushing performance, resulting in high final fineness.
The moveable jaw reciprocates, crushing the large rocks until they are small enough to fit through the opening at the bottom of the V. The Grizzly King Jaw Crusher is one example of an effective aggregate solution. Jaw Crusher Benefits. Every site has different needs and requirements, so jaw crushers can be found in different sizes and capacities.
Our jaw crushers are of the single-toggle type and feature a deep, symmetrical crushing chamber, a large feed opening for its size, and an ideal nip angle that offers smooth …
The Rose and English jaw crusher model equations were taken from the work of Gupta and Yang [4]. For a jaw crusher the reduction ratio (R) is defined with gape (G) as: (A.1) R = G L min [−] Therefore the close opening set (L min) for a jaw crusher can be written as: (A.1) L min = G R [m]

The motion of the swing jaw in a Blake crusher is predominantly vertical, which provides a compression action on the material. This vertical movement of the movable jaw plate is more efficient at reducing large, hard materials into smaller pieces, offering a higher reduction ratio and better uniformity of the product size.
The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It …
