Crushing Products Size and Shape -What to Expect
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, Crusher manufacturers publish grid charts, particle size cumulative distribution curves, and/or product size distribution tables to help predict the gradation of the crusher product. These charts, curves, and tables give the percentages passing or retained on standard size screens for each given setting of the crusher.Crusher Product Gradation Charts 911 Metallurgist

A time dynamic model of a high pressure grinding rolls crusher
When applying these ideas, the established roller crusher, previously modeled by Austin et al. (1980), The model is demonstrated to be able to predict throughput, power and product size distribution on the basis of 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 Minerals Free Full-Text An Improved High-Pressure Roll Crusher

Finite Element and Multibody Dynamics Analysis of a
Han et al. compared the hematite product characteristics in a high-pressure grinding roller and jaw crusher. They found that the grinding roller achieved a more uniform size distribution, more fines, The crushers in the software were assumed as homogeneous. The calculation of the PSD in the outlet solid stream was based on an empirical parameter that depends on the type of crusher and the PSD of feed. The outlet flow rate of the crushed product in the k-th size interval is calculated by Eq. (1). P k β = ∑ j ∑ i F ij S i β B ik βOptimization of particle size distribution in circulating fluidized

A similar particle size distribution was obtained for the three different HPGR products for both platinum ores, although the HPGR product with 3 mm operating gap (12 mm feed top size, MerenskyFig. 5 shows the product size distribution for both the softer ore with E b = 1100 J/kg and a harder ore with E b = 1500 J/kg. The crusher takes approximately 7 s to completely empty the batch load of 322 kg and the top size predicted is consistent with the typical design product size of 150 mm for this crusher configuration.Advanced comminution modelling: Part 1 Crushers

Due to single pass operation, it is evident that no middlings or over-size is produced. The normal speed of operation of commercial light duty rolls is 130–300 rpm compared to heavy duty rolls whose operating speeds are in the region of 80–100 rpm.Roll Crushers ScienceDirect

Maximum product bulk density is 1.9 to 2.1 t/m3 for average limestone feed-stock. Secondary applications are power driven, whilst tertiary duties are pressure driven. Mostly 5°/o-10% of the feed-size distribution is the maximum less than the closed side setting—except with modern cones that are trying to generate interparticle crushing.Crushing SAG Mill Critical Size Material. The relationship between the grinding power consumption and the product size distribution has been widely studied since it is a subject of major interest for plant design and optimization. The conventional approaches, generally of empirical nature, have led to the formation of equations such as Crushing SAG Mill Critical Size Material 911 Metallurgist
