Reduction ratio 6:1. Jaw Crushers use pressure to break up very hard, flaky, and slabby rocks by passing them between a moving surface and a stationary one. They are generally used for primary crushing but also provide great results with secondary crushing. Jaw crushers are excellent for breaking up concrete, rock and asphalt.As a rule, Jaw Crushers have a 6:1 or 8:1 ratio for crushing material. Still using the 32 x 54 Jaw Crusher example, the top size of the feed entering the crushing chamber has to follow the F80 rule that 80% of the top size feed material is smaller than the gape opening.McLanahan Jaw Crushers

Jaw crusher limitations. Jaw crushers typically produce less fine material than impact crushers. A jaw’s reduction ratio is approximately four to one, and a jaw crusher is commonly used as a primary crusher for initial size reduction or to produce non-spec material. However, fines are required to meet specific gradations and increase A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29”x49”, the crusher gape would be 32” and the width would be 54”.McLanahan How To Size A Jaw Crusher

Therefore, the crusher reduction ratio is 2. Calculating the Gape Size when the Crusher Reduction Ratio and the Set Size is Given. G = R r x S. Where: G = Gape Size R r = Crusher Reduction Ratio S = Set Size. Let’s solve an example; Find the gape size when the crusher reduction ratio is 8 and the set size is 4. This implies that; R Gyratory crusher: feed diameter 0.75 to 1.5m; reduction ratio 5:1 to 10:1, usually 8:1; capacity 140 to 1000 kg/s; Mohs hardness <9. More suitable for slabby feeds than jaw crusher. [reduction by compression].

Jaw crushers are generally considered a primary or first stage crusher. The maximum feed size can be as large as 80%-85% of the crusher’s gape or depth, while reduction ratios range from 2-3 times. Cone crushers are typically used in the secondary or tertiary stage after a jaw crusher’s begun the reduction process earlier in the circuit.There are lots of different kinds of crushers from jaw crushers to impactors and cone crushers. Crushing is an versatile process and the kind of crusher you need depends on the 'stage' of crushing. The three main stages of crushing are primary, secondary, and tertiary all of which have their own unique benefits.Types of Crushers: What You Need to Know Machinery Partner

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 The ore had to be crushed in a C-63 type jaw crusher 630 × 440. At a reduction ratio of 4, 18% of the ore was below the maximum size required. Determine: 1. The kiln accepted top size of 10 cm. A single toggle Blake jaw crusher was available for crushing.
