Reduction of the speed leads to a decreased fine fraction of the sample and to more particles within the desired size range. Especially for this type of application, the lowest speed of the SM 300 was reduced to 100 min-1.This is also beneficial for grinding heat-sensitive materials: reduced speed results in less energy input, preventing the sample from getting too warm …
Therefore, if minimum production of fines is desirable, it is logical that the heavy end of the 7:1 reduction should be handled in the latter machine. Generally, for such a case, the split would be about 3:1 to the standard …

Let us suppose that we wish to know how much of the product of our primary crusher will be retained on a 1.5″ square opening screen, so that we may estimate the size and number of secondary crushers required to recrush …
The feed for Gyradisc crushers usually has a topsize not larger than 75MM (3 In.) for the larger units and 30MM (1¼ In.) for the smaller size crushers. Gyradisc crushers differ from conventional cone-type crushers because the comminution of material is achieved by a reduction process called Inter-Particle Comminution.

In the study of Kou et al. (2011b), although the 28-day cumulative pore size distribution showed that RAC with coarse RCA had higher porosity, after 5 years of water curing, RAC specimens showed a reduction in porosity of about 45%, whereas that of the control concrete was about 29%. This improvement of the RAC can be explained by the ...
The operation is similar to the standard cone crushers, except that the size reduction is caused more by attrition than by impact [5]. The reduction ratio is around 8:1 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 ...

A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6:1 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 8:1 may be possible in certain coarse crushing applications.
