DetailsIn a crusher's design, attention to the reduction ratio is critical. This ratio reflects the degree to which the material is reduced in size from the feed to the product. A high reduction ratio indicates a powerful crushing capacity, such as reducing 150-centimeter-wide iron ore to a 30-centimeter-wide material.

DetailsJaw 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.

Here, we turn the spotlight on cone crushers, used more often for The development of high reduction ratios has also been important Continue Reading → Crushers Are Used In Food Processing Recycling Industries This is extremely important in food processing, where granularity is often …
DetailsUnless very large diameter rolls are used, the angle of nip limits the reduction ratio of the crusher, and since reduction ratios greater than 4:1 are rare, a flowsheet may require coarse crushing rolls to be followed by fine rolls. ... The roll surfaces play an important part in the process of nipping a particle and then dragging it between ...
DetailsPower Consumption of Roll Crushers. Within the same reduction ratio the power consumption of roll crushers varies widely. The power required could be expressed by the general equation (6.8) P = capacity × reduction ratio × work index. In industry, the low pressure smooth surfaced rolls are designed to draw 8–50 kW of power under dry …
DetailsJaw Crushers; Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).

DetailsWith a crushing efficiency measured by a reduction ratio of 3:1 to 5:1, these crushers are especially good for materials like coal, limestone, and others that aren't too rough on equipment. Roll crushers are really cool because they crush things into smaller pieces. They don't make a lot of dust or tiny bits.
DetailsBall mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders e.g. a rod mill. Ball mills are usually either of the grate (diaphragm) or overflow type.
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 …
DetailsThe 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 …

DetailsFor 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] Rose and English [4] determine the size for which 80% of the feed passed, by considering a large data set relating the maximum particle size to the ...
DetailsThe gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place. Here, the maximum reduction ratio is about 8:1.

Roll crushers – Roll crushers are a compression-type reduction crusher with a long history of success in a broad range of applications. The crushing chamber is formed by massive drums, …
DetailsCone crushers are similar to jaw crushers in that they are relatively low wear. Impact Crushers: Impact crushers can yield a considerably higher reduction than jaws or cones, from 12-15 to 1. This means one can take a 12" or 15" piece and reduce it to 1". This is a large reduction but there is a cost for it.
