SPECS. Crusher Dust (0-4 mm) This type of aggregate is used for making various reinforced concrete structures. It is also used in Road construction The shape of the particles help make concrete more cohesive, perfect gradation ensures fewer voids and increases the compressive strength.
aggregate have openings ranging from 150 m to 9.5 mm (No. 100 sieve to . 3 8. in.). The 13 standard sieves for coarse aggregate have openings ranging from 1.18 mm to 100 mm (0.046 in. to 4 in.). Tolerances for the dimensions of open-ings in sieves are listed in ASTM E 11 (AASHTO M 92). Size numbers (grading sizes) for coarse aggregates
Apr 28, 2020 The general idea is that the smaller the aggregate size, the more we need equipment to produce it. Production of aggregate starts typically from 800 mm pieces of blasted material. One crusher can only reduce the size by a certain amount. For example, manufactured sand is a very fine product with high quality requirements.
Dec 02, 2020 Coarse aggregate (stone) The aggregate with particle size between 4.75 mm and 9.0mm is coarse aggregate, commonly known as the stone. It can be divided into two types, that is, gravel and pebble. Gravel is natural rock or rock by mechanical crushing, screening system, and the particle size is larger than 4.75 mm of rock particles.

Cone crushers . Cone crushers resemble gyratory crushers from technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. Sometimes, however, the grain size of the processed material is small enough by nature and the traditional primary crushing stage is not needed.
Crushers are mounted on sturdy welded steel base frames with CSA-rated electric motors and are fully equipped with pulleys, feed hoppers, and safety guards. Replacement Jaw Plate sets are available. LC-27 2.25x3in Laboratory Jaw Crusher reduces 2in (50mm) aggregate, ore, and rock materials to a product with 80% passing a No. 14 (1.4mm) sieve.

Recycled aggregate comes primarily from PCC and AC from road rehabilitation and maintenance, demolition, and leftover batches of AC and PCC. After processing, the rocks retain bits of cement or asphalt. A roadway is built in several layers pavement, base, and sometimes subbase. The pavement is the surface layer, and is made of PCC or AC.
