Inversely, at a given reduction ratio, effective streamlining could increase the capacity by 30%. The typical reduction ratio is bound to be between 6 and 8 and is similar that of jaw equipment. Applying the crushing force by rolling the nut breaks flats and gives a product that is more “cubic” than the jaw crusher. –احصل على السعر
Fig. 6.4 is a typical set up where ore crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in open circuit followed by finer size reduction in a closed circuit by roll crusher. Such circuits are chosen as the feed size to standard roll crushers normally do not exceed 50 mm.احصل على السعر
2021416 A measure of the size reduction achieved for a particular crusher application is the reduction ratio. A cone crusher in a secondary crushing application will typically work with a 3.5:1 to 5:1 reduction ratio. احصل على السعر
Cone crushers. Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in large-scale industries for crushing various types of materials into smaller sizes. It works by applying pressure onto the material and squeezing it against a rotating mantle to create compression and force.احصل على السعر
