A stone crusher machine (also called a stone sand making machine) is a device designed to produce artificial sand from various types of rocks, including granite, limestone, and basalt. These machines typically use a high-speed rotor that crushes rocks into smaller pieces and then further grinds them into sand-sized particles.

Types of Stone Crusher Machines:

  1. Jaw Crusher: This machine crushes large stones by compressing them between two jaws. It’s primarily used for primary crushing.
  2. Impact Crusher: A high-speed rotor throws the rocks against a crushing plate to break them into smaller fragments. This is typically used for secondary crushing.
  3. Cone Crusher: This machine uses a rotating cone to crush stones into finer particles and is ideal for secondary and tertiary crushing.
  4. Vertical Shaft Impact Crusher (VSI): It uses high-speed rotating impellers to crush rocks, turning them into sand.

Working Principle:

  • The stone is first fed into the machine, where it undergoes a series of crushing stages.
  • After the primary crushing, the materials are screened, and the appropriate size fraction is sent for further crushing.
  • The final product is artificial sand, which can be used in construction, concrete, and other industrial applications.

Applications:

  • Manufacturing of artificial sand for construction.
  • Aggregates for concrete and road-building.
  • Quarrying operations.
