Primary Gyratory Crusher Reduction Ratio Gyratory crushers are ideally suited for high capacity primary crushing that require a reduction ratio of 61 and provide a tight control over the rocks leaving ... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
Here the maximum reduction ratio is about 81 In some cases installation of a tertiary crusher is required where the maximum reduction is about 101 The secondary crushers are also designed on the principle of gyratory crushing but the construction details varyFurther Details
Jaw crusher feed diameter 01 to 15m reduction ratio 51 to 101 capacity 1 to 300kgs Mohs hardness 9 reduction by compression Gyratory crusher feed diameter 075 to 15m reduction ratio 51 to 101 usually 81 capacity 140 to 1000 kgs Mohs hardness 9 More suitable for slabby feeds than jaw crusher reduction by compressionFurther Details
Jaw 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 The primary operating variable available on a crusher is the set and on jaw and gyratory the openside set OSS is specified This reflects the fact that considerableFurther Details
The reduction ratio is around 81 and as the product size is relatively small the feed size is limited to less than 50 mm with a nip angle between 25° and 30° The Gyradisc crushers have head diameters from around 900 to 2100 mm These crushers are always operated under choke feed conditionsFurther Details
The primary gyratory crusher offers high capacity thanks to its generously dimensioned circular discharge opening which provides a much larger area than that of the jaw crusher and the continuous operation principle while the reciprocating motion of the jaw crusher produces a batch crushing action Reduction ratio must be limited to 3Further Details

To accomplish this reduction in size takes several steps or stages of crushing and grinding Primary crushing is the first of these stages Generally speaking there are two types of primary crushers lets compare them GYRATORY CRUSHER or a JAW gh they don’t look anything like they do have similarities that put them into the same class of crusherFurther Details
