However, because nutritionally complete chicken feeds already contain crushed limestone, a fast-release, small particle size source of calcium, eggshells are unnecessary and redundant. Crushed eggshells are neither necessary, nor helpful to laying hens as the excess calcium must be filtered out of the hen's body, taxing her kidneys.

Thom [35] also found that for crushed dolomitic limestone samples, the stiffness decreased up to 25% with a reduction in maximum particle size from 30 mm to 3 mm. Conclusions This research aimed to determine the influences of individual aggregate properties affecting the strength characteristics of aggregates used as base/subbase …

As for the aggregate materials, crushed limestone and crushed gravel, commonly used in Illinois in base/subbase applications, were considered. Illinois dense graded base specifications allow aggregate materials with a maximum particle size of 25 mm for the CA 6 specification and 50 mm maximum particle size for the CA 2 aggregate.

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.

The authors suppose that the crushed gangue with large particle size bite each other to form a more stable structure to resist axial pressure, and the axial stress of 5 MPa is too low to destroy the structure. Thus, the compressive deformation of large …
