Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.

I have a lot of large sized gravel left over from when I set up my present tanks and sieved their gravel. I have a mixture of Onyx gravel, lava rock, and Carib Sea African cichlid gravel that doesn''t pass through 1/2 inch mesh screens. I probably have about 150 lbs. I would really like to know how to crush it into smaller pieces.

To crush heavily compressed sand in a sand quarry was a second, very different task for a Rockster impactor. The sand is excavated with a vibro-ripper from an extremely strong quarry wall. “This ripper produces solid lumps of sand. Then the excavator loads lumps into the crusher with a 5 mm screen, and we get great sand ,” says CSB owner

Like crushed stone, gravel can be used as an aggregate for pavement, ready mix concrete, or other construction applications. Best applications for crushed stone We have already referenced many places where crushed stone is used, but the most common are construction projects that need concrete, solid bases, or drainage systems.

Crushed gravel also helps to keep soil in landscaping areas moist. Any kind of covering on all types of topsoil can help the soil stay moist by allowing it to retain more water. This is why mulch is used; it helps the soil retain water after rainfall by preventing evaporation. Crushed rock does the same thing, and many people find it much more

Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.

Any aggregate particle that retains of sieve #4 is called ‘coarse aggregate’. Coarse aggregates (also known as crushed stones) are majorly added in the concrete mix for strength gain purposes. They can be obtained by blasting heavy rock boulders. In Pakistan, we generally use Margalla Crush, Sargodha Crush and Sakhi Sarwar Crush

Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for further processing

The crushed aggregate is divided into high-quality recycled aggregate of 5-20 mm by secondary screening, which can be used in the concrete manufacturing of C25-C30. The high-quality recycled fine aggregate of 0.15 mm-5 mm and the fine powder of 0.15 mm or less are selected by tertiary screening.

Crushed stone is commonly used as an aggregate for construction, including roadways. It is also used in landscaping and gardens. The angular surface, roughness, and larger crushed stone make it a popular choice for gardens and pathways. It provides solid traction, doesn''t easily sink into the ground, and resists weed growth.
