Jul 25, 2018· The duty of the primary crusher is, above all, to make it possible to transport material on a conveyor belt. In most aggregate crushing plants, primary crushing is carried out in a jaw crusher, although a gyratory primary crusher may be used. If material is easily crushed and not excessively abrasive, an impact breaker could also be the best
As to the crushing methods, there are two most common types: compression crushers and impact crushers. Compression crushers adopt the theory of squeezing or pressing between rigid surfaces, such as jaw crusher, cone crusher, dual-roller crusher, etc., while impact crushers employ impact, such as impact crusher, vertical shaft impact crusher, super-fineness energy-saving crusher, etc.

IMPACT CRUSHING Impact crushers may be used as primary, secondary, or tertiary crushers. Despite having a somewhat higher operating cost than other crushers, they tend to produce a more uniform particle shape. Impact crushers usually will benefit the aggregate better than compression crushers, and they may generate more fines.
Crushing Aggregate Process And Planning We are a large-scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment.

Impact and Crushing Value Aggregate Crushing Value (ACV) Sets. UTA-0630 Aggregate Crushing Value (ACV) Set Ø 150 mm BS. UTA-0640 Aggregate Crushing Value (ACV) Set Ø 75 mm BS. The Aggregate Crushing Value (ACV) Test Set measures how resistant an aggregate is, when being crushed under a gradually applied compressive load.
The impact crusher (typically PE series) is widely used and of high production efficiency and good safety performance. The finished product is of cube shape and the tension force and crack is avoided. Compared with hammer crusher, the impact crusher is able to fully utilize the high-speed impact energy of entire rotor.
Impact Crushers: the all-in-one rock crushing solution. The Sepro Impact Crusher is a cost-effective rock crushing solution designed for dependability and versatility. Fully-equipped to act as the primary crusher for limestone processing, concrete recycling, asphalt recycling, and more—the impact crusher can also function as a secondary crusher.
Coarse aggregate occupies 70% to 80% of the volume of concrete. Aggregates are the material that the cement paste coats and binds together. The quality of aggregates imposes a significant impact on the properties of concrete like workability, strength, weight, durability etc.
