Jaw Crushers typically have a reduction ratio of 6:1, which means a 30" feed will be reduced down to 5" at the smallest size. The product size can be adjusted by opening or closing the gap between the jaw dies at the smallest point.
DetailsJaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.
DetailsJaw Crusher Reduction Ratio. Either an 8-to-1 or 6-to-1 ratio should be the target reduction ratio for maximum jaw crusher efficiency. This setting typically provides an ideal P80 factor—when 80% of crushed material produced by primary crushing will pass screening after processing. A smaller closed-side setting will produce more fines.
DetailsIndustry standards commonly dictate that the ideal reduction ratio of a jaw crusher should be 6-to-1. Rule #3: Define tonnage goals. The desired production capacity, or tonnage-per-hour required directly correlates to the width of …
DetailsThe size of the crushed product depends on the CSS. You can change the CSS by moving the toggle plate. A smaller CSS makes a finer output. A larger CSS makes a coarser product. Jaw crushers usually have a reduction ratio of 4:1 to 9:1. This means they can make the feed material up to 9 times smaller in one pass.

DetailsCone Crushers: Cone crushers are considered a secondary crusher. You shouldn't feed any material larger than 4" into one, but it can yield an 8 to 1 reduction. This means we can go down to ½" and even 3/8" depending on the feed size. Cone crushers are similar to jaw crushers in that they are relatively low wear. Impact Crushers: Impact ...
DetailsA 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 …
DetailsThe reduction ratio is defined as the ratio of the feed size to the product size, and it can be optimized by selecting the appropriate jaw crusher model, adjusting the feed size …
DetailsThe reduction ratio for a jaw crusher is typically 6-to-1, although it can be as high as 8-to-1. Jaw crushers can process shot rock and gravel. They can work with a range of stone from softer rock, such as limestone, to harder granite or basalt. ... Double roll crushers offer up to a 3-to-1 reduction ratio in some applications depending on the ...
DetailsThe 1-in. screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is 0.90 and that screen capacity is 2.1 x 0.9 = 1.89 tph/sq ft. The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq ft.
DetailsSize Reduction) A crusher is a machine designed to reduce the size of large rocks to ... How Jaw Crushers Work. A jaw crusher uses compressive force for breaking ore pieces. ... A typical jaw crusher will have a crushing ratio of between 6:1 to 8:1 i.e. the feed material size is reduced by a factor of 6 or 8.
DetailsFor a given ratio-of-reduction, the type of crusher with a flared crushing chamber will usually deliver a cleaner product than any of the older types; conversely, more reduction …

DetailsThe largest size of ore pieces mined measured 560 mm (average) and the smallest sizes averaged 160 mm. The density of the ore was 2.8 t/m3. The ore had to be crushed in a C-63 type jaw crusher 630 x 440. At a reduction ratio of 4, 18 % of the ore was below the maximum size required. Determine: (a) The maximum operating capacity of the crusher ...

DetailsOur 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 material flow and high reduction efficiency. Jaw crushers are normally capable of a reduction ratio of 1:2 or 1:3. This ratio is affected by the feed
DetailsJaw Crusher Reduction Ratio. Either an 8-to-1 or 6-to-1 ratio should be the target reduction ratio for maximum jaw crusher efficiency. This setting typically provides an ideal P80 …
DetailsCone Crushers are are well suited for hard to medium hard materials. They perform well in abrasive material with relatively low operating costs. In secondary applications, they typically provide a reduction ratio of 6:1, through 8:1 reduction ratios can be achieved with coarser applications. Horizontal Shaft Impactors
DetailsFrom Allis-Chalmers' Superior Primary and Secondary Crushers. ° Actual required depends on stone hardness, reduction ratio, and so on. If a 60-in. gyratory crusher is to process material from a quarry where a shovel loads the raw material, the shovel would probably have to have a dipper capacity of at least 5 cu yd to be compatible.
DetailsSetting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
DetailsSome models can even process giant boulders up to one cubic meter in size. They also have a high reduction ratio of up to 8:1, meaning they can significantly reduce material size in just one go. Flexibility in Output Size: The closed side setting (CSS) of a jaw crusher, which is key to determining the size of the end product, can be adjusted.
