Pebbles, this kind of pure natural stone, is widely regarded as a high-quality raw material for producing sand, gravel and aggregates due to its hard texture. It is not only used in public buildings, villas, courtyard buildings, road paving, park rockeries, bonsai filling materials, and garden buildings, but also an important material for other high-end and superior buildings.
The types of pebble crushers are diverse, including jaw crushers, vertical impact crushers, impact crushers with counter-rotating discs, and cone crushers, etc. According to the requirements of the output particle size, the sand-making process usually involves two steps: coarse crushing and fine crushing, corresponding to the first-level crushing and the second-level crushing respectively. Moreover, due to the different hardness of pebbles, the selection of crushing equipment also needs to be determined based on the crushing force.
Choosing the right crusher is crucial for reducing wear on vulnerable parts, extending the lifespan of the machine, and improving work efficiency. For crushing gravel, Dahua Heavy Industry recommends using a vertical impact crusher. Here are several reasons for choosing a vertical impact crusher to crush gravel:
How do pebbles break? Why is a vertical impact crusher used?

- Reduce wear on vulnerable parts and extend the machine's lifespan. The main chemical component of pebbles is silicon dioxide. Using a vertical impact crusher can significantly increase the crushing ratio and production efficiency, while reducing the wear on vulnerable parts and extending the machine's service life.
- Produce high-quality sand and gravel aggregates. The vertical impact crusher can not only crush pebbles but also perform coarse grinding, resulting in over 90% of high-quality cubic aggregates with uniform particle size and reasonable gradation.
- Provide greater production capacity. The vertical impact crusher can offer greater production output when crushing pebbles. Its modular design allows for adjustment of the cavity size according to the requirements, enabling flexibility in crushing and wide application scope.
Shanghai Cronus, as a professional manufacturer in the field of mining crushing equipment, offers various types of vertical impact crushers to meet diverse production requirements. We deeply integrate the production capacity planning, material characteristics and application scenarios of our customers to tailor high-adaptability customized crushing solutions.
