As can be seen from Table 3, the apparent density and water absorption rate of recycled fine aggregate are, respectively, smaller and higher than those of natural fine aggregate.The water absorption rate of recycled fine aggregate is 75.65% greater than that of natural fine aggregate. This is mainly because the recycled fine aggregate is …

Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing.
