Crushed Stones #8 are also known as clean crushed stones, or 3/8-inch washed stones. They are about 3/8 to ½ an inch in diameter. Crushed Stones #8 are considered an aggregate. Following crushing which reduces the size of stones, it is passed through a 3/8-inch square screen. Then the Crushed Stones #8 are cleaned, and the dust is removed.
To apply what this means to your crusher, operations produce the exact sizes in the reduction process that their market demands. In the past, quarries produced a range of single-size aggregate products – up to 40 mm in size. Still, the trend for highly specified aggregate means products are increasingly finer.
