Coarse crushed aggregate is commonly used in landscaping designs. All aggregate is divided into two types fine and coarse. Fine aggregate is broken up into smaller pieces than coarse aggregate. When put through a separator or aggregate washer, coarse crushed aggregate will pass through a 3-inch (7.62-cm) sieve but will not go through a No. 4 sieve.

For adequate consolidation of concrete, the desirable amount of air, water, cement, and fine aggregate (that is, the mortar fraction) should be about 50% to 65% by absolute volume (45% to 60% by mass). Rounded aggre- gate, such as gravel, requires slightly lower values, while crushed aggregate requires slightly higher values.

Aug 01, 2019 Abandoned concrete blocks are high-quality concrete aggregates which have many advantages. For example, after the buildings are dismantled, the high-quality concrete blocks and silt after crushing and screening can be used as recycled coarse and fine aggregates for concrete. The fine powder can be directly used as the raw material of cement.

Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), which typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches). The material (throughs) from the second level of the screen bypasses the secondary crusher because it is sufficiently small for the last crushing step.
