Jaw crushers offer reduction ratios of up to about 61 while cone crushers can reduce material size up to a maximum of 81 ratio. The finer the crushing the smaller the reduction ratio. As a basic rule jaw crushers are the primary crusher taking the mined aggregate and reducing it to a size that a cone crusher can accept.

Oct 01 2017 Rock Crushers fill the duty of rock size reduction and can be classified in various stages of duties. Primary crushing is the first crushing stage; secondary crushing is the second; Tertiary crushing is the third; Quaternary crushing is a rare forth stage of rock crushing Coarse crushing includes crushing operations discharging at sizes 4- to 6-in. or coarser; intermediate crushing .
Dec 26 2015 Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80 of the gape. 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.

Major rock types processed by the crushed stone industry include limestone content 4 throughput rate 5 crusher type 6 size reduction ratio and 7 fines. 1 Crushing Both crushers have the same reduction ratios between 4 1 and 7 1 but the optimum types of feeds vary somewhat.
Reduction ratios will vary with each application within each family of Hammermills and by the amount of applied energy. HammerMaster Crushers are limited by horsepower and feed size so depending on the grate selection and desired product size in closed circuit reduction ratios
Zong-Xian Zhang in Rock Fracture and Blasting 2016. Abstract. Various types of rock fracture occur at different loading rates. For example rock destruction by a boring machine a jaw or cone crusher and a grinding roll machine are within the extent of low loading rates often called quasistatic loading condition.On the contrary rock fracture in percussive drilling and blasting happens .
A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 61 reduction ratio. Thus with a 3⁄4 closed side setting the maximum feed would be 6 x 3⁄4 or 4.5 inches. Reduction ratios of 81 may

For primary crushing with a reduction ratio of 6 to 1. When a relatively coarse product is desired top size usually larger than 38 mm 1 12 Closed Circuit Crushing System To control top size from a single crusher operating in an open circuit material must remain in the crushing chamber until the material is reduced to top size.
Depending on the type of an impact crusher they are known for either high reduction ratios or capabilities to produce precisely shaped cubical end products. Impact crushers can be used in all different stages of size reduction from primary crushing to the last step of the crushing process.
Jun 02 2017 Many different types of crushers exist with varying designs and crusher processes. The proper choice is dependent on several factors including the hardness of the material to be crushed the abrasive properties of the material the moisture content and the reduction ratio required.
compressive forces to each rock. Another type of crusher accomplishes similar results using impact hammers or blow bars mounted on a rotor thereby producing high kinetic energy impacts on each rock at velocities of around 30 ms. These impact crushers are capable of producing a high ratio of size reduction in one stage of crushing.
crusher tools E.G. Jaw liners are subject to numerous pressure and impact stresses. Several other factors affect the wear lifetime of crusher wear parts as listed in below Diagram . Wear occurs in all crushers however wear costs can be controlled by selecting the correct crusher type for the abrasive content of the material to be crushed.
