(3) σ n is the normalized standard deviation in particle size and x max is the largest particle size in the feed. Eq. (3) maps maximum particle size and the width of the size distribution into a bulk density for a specific particle bed. The top size of the bed determines which of the equations is used.
The maximum particle size of a limestone sample received from a cone crusher was 2.5 cm. It was required to further crush it down to 0.5 cm in a roll crusher with smooth rolls. The friction coefficient between steel and particles was 0.25, if the rolls were set at 6.3 mm and both revolved to crush, estimate the diameter of the rolls.

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.
The product of a jaw crusher will have a size distribution such that the -80% fraction size (d80) is slightly less than the open-side setting of the crusher. For example, if the open- side setting is 6 inches, the d80 product size will be 5¾ inches. ... the maximum particle size that is normally desired for skip hoisting is obtained when run ...
1. Control material size The crusher has a maximum feed size. When the feed particle size is too large to the equipment caused serious damage.

A Gyratory crusher not only affords a maximum capacity-to-size ratio, but provides the variable factors which facilitate increasing or decreasing capacity as the need arises. ... is actually the total work input in kwhr per short ton required to reduce a given material from theoretically infinite particle size to 80% passing 100 microns or ...
Maximum particle size should not exceed 80% of the gape. For example, a 400- by 600-mm crusher will accept a maximum lump size of 400 by 0.8 = 320mm. In actual operations, the crusher will occasionally accept particles up to the gape size, as long as bridging does not occur. The overhead eccentric is an integral part of the moving plate, …
Quist et al. optimized the ore particle size distribution in the crushing chamber of cone crusher based on the DEM and the bonded particle model [11, 12]. Furthermore, when simulating the working process of the crusher by the DEM, ore particle modelling is the key. ... between the sub-spheres used to compose ore particle, and the …
Crushing produces mainly coarse (TSP and PM 10) dust particles which settle near the dust source. The mass concentration of coarse particles varied from few tens of μg/m 3 to over 6 × 10 3 μg/m 3 downwind from the crusher.
