A sand making machine, also known as a vertical shaft impact crusher, is specialized equipment designed to produce artificial sand and crushed stones. It is widely used to process raw materials like rocks, gravel, and river stones into high-quality construction sand with uniform particle sizes.
The sand maker uses a high-speed rotor to throw raw materials into the crushing chamber, where they collide with impact plates or other particles. This process, known as “rock-on-rock” or “rock-on-iron” crushing, breaks down materials into finer, well-shaped sand grains through repeated impact and friction.
A sand making machine is often used in combination with other mining equipment such as jaw crushers (for primary crushing), cone crushers (for secondary crushing), vibrating screens (for sieving), and sand washers (for cleaning impurities). This forms a complete sand production line.
