Product Introduction
The VSI sand maker, also known as Vertical Shaft Impact Crusher, saves 50% energy compared with traditional sand‑making machines. Developed based on feedback from end‑user operation data, it is an eco‑friendly manufactured‑sand equipment featuring high production efficiency. It produces high‑quality finished sand with excellent particle shape, and the proportion of particles below 5 mm can reach over 80%. It is widely applied in artificial manufactured sand, cement, construction, chemical industry and other fields.
Working Principle of VSI Sand Maker
Raw materials enter the machine through the feed hopper and pass through the central feed opening into the high‑speed rotating impeller, where they obtain acceleration up to dozens of times gravitational acceleration before being ejected at high velocity from the impeller. The ejected materials first collide with another portion of freely falling rebounded materials. Together they strike the material lining (Rock‑on‑Rock mode) or impact block (Rock‑on‑Iron mode). The materials are rebounded obliquely upward to the top of the vortex chamber, then change direction and move downward. They further collide with materials discharged from the impeller passages to form a continuous material curtain. Inside the vortex crushing chamber, each material particle undergoes two or multiple impacts, friction and grinding for fragmentation. The crushed materials are discharged from the bottom discharge outlet.
Product Introduction
1. Intelligent Control & Cost Saving Equipped with an automatic control system, the VSI sand maker supports remote computer‑based control for easier and faster operation. A vibration display and alarm device are installed to ensure personal and equipment safety.
2. High Efficiency & Superior Particle Shape Featuring a special feeding‑crushing structure and multiple crushing cavity types, the machine enables switching between “Rock‑on‑Rock” and “Rock‑on‑Iron” modes. Together with the new deep‑cavity impeller, it delivers higher production efficiency. The finished sand has uniform particles with adjustable fineness modulus for higher application value.
3. Eco‑friendly Performance It adopts a scientifically‑designed internal self‑circulating air‑flow vortex chamber, paired with a pulse dust collector. Durable rubber bases are fitted for stable installation and vibration reduction. Noise eliminators are also equipped to realize environmentally‑friendly sand production.
4. Long Service Life The VSI sand maker is constructed of wear‑resistant, corrosion‑resistant and high‑compressive‑strength materials. The impact‑angle design inside the crushing chamber minimizes friction against wear parts, cutting operating costs by 30% compared with conventional equipment. The modular throwing head only requires replacement of worn segments, which effectively reduces operational costs.
