Apr 01, ideally, the reduction ratio of a jaw crusher should be 6:1. there are different ways to calculate reduction ratio, but the best way is something called the p80 factor. the reduction ratio is then calculated by comparing the input feed size passing 80 per cent versus the discharge size that passes 80 per.
Apr 16, a cone crusher in a secondary crushing application will typically work with a 3.5:1 to 5:1 reduction ratio. tertiary cone crusher configurations typically work with a reduction ratio of 2.5:1 to 4:1. the reduction ratio is defined as the ratio of the feed size for which 80 per cent will pass (f80), divided by the product size for which 80 per cent will pass.
Apr 24, roll crusher roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. roll crushers have a theoretical maximum reduction ratio of 4:1. if a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from.

Feb 25, roll crusher • the reduction ratio and efficiency of roll crusher is very low. • the main advantage associated with roll crushers is small proportion of fines produced and more uniform size of product crushed, than the other crushers. • low capacity • low reduction ratio = f/p • sensitive to top size 2/25/ 6:58:05 am 38.
Jan 01, taggart expressed the relationship between crusher capacity and reduction ratio in terms of a reduction ton or tonne, q r defined as (4.22) q r = q t ⋅ r 80 where q t is the capacity in terms of actual tonnage crushed per hour. the quantity of feed actually crushed is determined by subtracting the feed undersize from the total quantity of.
Jan 12, 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 machine, and 4:1 to the fine reduction crusher. screening crusher.
Maximum reduction ratios with a combination of variable speed and large throw, raptor cone crushers provide high reduction ratios. because of their efficient crushing action, the crushers have a large power utilisation per cone diameter. the high cavity density improves.
