Size Distribution For Roll Crusher

An improved approach is presented to model the product particle size distribution resulting from grinding in high-pressure roll crusher with the aim to be used in standard high-pressure grinding rolls (hpgr). this approach uses different breakage distribution function parameter values for a single particle compression condition and a bed compression condition.

Grinding of material in hpgrs has proven to be more cost efficient as compared to conventional mills and crushers. especially downstream processing stages such as ball-milling are more energy-efficient with an hpgr due to the finer product size distribution coming out and the additional effect of micro cracks within the product particles.Reduction cycle. generally gyratory crushers, jaw crushers, high speed double roll crushers, low speed sizers, impactors and hammer mills are used as primary crushers. in the secondary and subsequent stages, the material is further reduced and refined for proper size The 24″ diameter roll crusher has an effective nip of about 14″ maximum the 36″ machine will grip stone up to about 24″ maximum and the 60″ crusher will handle ledges up to about 36″ thickness. these thickness are based on limestone of medium hardness for harder materials the advisable thickness is Roll crushers do, however, give a very close product size distribution, and if the ore is not too abrasive, they do not have high maintenance costs. roll crushers have a theoretical maximum reduction ratio of 41. if a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 12 inch. moreFeb 26, 2016 the difference between the cumulative percentages at the 3.5″ and 1.5″ points on the curve gives us the amount, of such product to be expected from the output of the primary crusher this is 85 minus 43, or 42 of the primary crusher product. if our problem had covered a crushing condition calling for 80 instead of 85 passing the opening Roll crushers do, however, give a very close product size distribution, and if the ore is not too abrasive, they do not have high maintenance costs. roll crushers have a theoretical maximum reduction ratio of 41. if a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 12 inch. roll If a 2 inch particle is fed to the roll crusher, the absolute smallest size one could expect from the crusher is 12 inch. toothed roller crusher will only crush material down to a minimum particle size of about 10 mesh 2 mm. some major advantages of roll crushers are they give a very fine product size distribution and they produce very Crusher and distribution. size distribution of roll crusher . size distribution of roll crusher size distribution of roll crusher the capacity of the singleroll crushers is a function of the roll gap the roll length and the speed and ranges from about 30 tonsh 27 metric tonsh for a 24inchlong 61 cm roll crushing to inch 2 cm up to approximately 1500 tonsh 1360 metric .
