Crushed stone usesĬrushed stones’ most popular use is building and construction. There are sizes for large projects, lining waterbodies, making pavers, and so on. The specific application depends on the gravel size or grade. There are numerous uses of crushed stones and gravel. Pea gravel is about ¾ inches in size, while crushed stones are anything from screenings to 2-inch rocks. The difference between crushed stone and pea gravel is the same as gravel and crushed stones. They vary according to the color of the parent rock, i.e., brown, black, gold, copper, blue, yellow, greenish, etc. Some gravel colors include yellow, white, black, blue, beige, blue, gray, and beige.

Sizes vary from granule (coarser than sand) to pea-size to pebbles to river rock with some categorization has cobblestones and boulders. Their angular and jagged d edges allow them to pack well and minimally move. Round with a smooth surface if they are inside a waterbody bed.Īngular shaped with jagged edges due to the crushing actionĭon’t pack and loosely roll around due to the round shape and smooth edges. ![]() Manufactured, i.e., broken down using crusher They form via natural weathering and erosion over a long time. gravel comparisonīefore we look at the uses of gravel and crushed stone, let us make a short comparison to help clarify everything further. Therefore, although different in how they are made, there are instances when these two terms mean the same thing Crushed stone vs. However, it is worth noting that in the US, gravel and crushed stones mean any rock less than two inches in size but is coarser than sand (0.0625 o 2 millimeters).

Manufacturers use different rocks to make them.Ĭommonly used stones are limestone, granite, dolomite, and trap rock (basalt, gabbro, peridotite, and diabase). Therefore, you expect them to have angular, sharp, and jagged edges. Typical primary crushers are jaw and gyratory, while secondary/tertiary crushers include cone, impact (hammer), and roll crushers.
