1. Features of Vertical Shaft Impact Crusher

Innovative Design, Enhanced Efficiency
The impeller has been newly engineered with a four-port structure, significantly increasing material throughput. Compared to traditional three-port designs, this upgrade boosts crushing efficiency by up to 20%.

Advanced Technology, Lower Costs, Higher Returns
Adopting a “rock-on-rock” crushing mechanism reduces wear and operational expenses. Optimized impeller structure and manufacturing process extend its service life by 30% to 200%, depending on material characteristics, compared to earlier models.

Exclusive Design, Reliable Performance
The transmission system features a patented cartridge-type bearing seal that effectively prevents leakage, with three national patents granted. High-quality bearings further ensure stable operation and reduce mechanical failure.

Effortless Maintenance, Continuous Operation
A newly designed lifting mechanism simplifies maintenance, reducing labor intensity. The streamlined internal design minimizes blockages caused by high-moisture materials, decreasing downtime and enabling continuous, efficient production.

2. Working Principle

Driven by the motor, the main shaft rotates the impeller at high speed. Materials entering the center of the impeller are accelerated and flung outward into the surrounding crushing chamber. Here, they collide with the material lining the chamber walls, transforming kinetic energy into the energy required for crushing and shaping.

This process repeats multiple times, allowing the material to be crushed and reshaped continually by interacting with other particles in a circulating airflow—commonly referred to as “rock-on-rock” crushing. Finished products exit through the bottom discharge outlet.

In addition to this, the crusher can also operate in a “rock-on-steel” mode, where accelerated material impacts directly against the chamber liners. Unlike the “rock-on-rock” method, this approach allows materials to be discharged after a single impact, offering a high reduction ratio and is particularly effective for coarse crushing applications.
