**The Core of VSI: Rotor Design**
The rotor is the "heart" of the VSI, designed to achieve a perfect balance between high capacity and low energy consumption. The wear parts of the rotor are distributed both inside and on the outer surfaces. These parts utilize different material technologies to resist impact wear and abrasive wear, thereby extending the equipment's service life.

**Key Components of VSI**
The VSI sand-making machine consists of several critical components, each playing a vital role in the crushing process. The main components include:
- **Feeding System**: Feed hopper, feed tube, feed eye ring
- **Rotor System**: Rotor tip, tip/cavity wear plate, lower wear plate
- **Distribution System**: Distributor plate, spider, spreader plate
- **Wear Castings**: Gusset wear casting, rotor weldment, etc.
The precise coordination of these components ensures efficient and stable operation of the equipment.
