Working Principle and Structural Composition of the Vortex High-Impact Crusher

Working Principle:

The vortex high-impact crusher primarily consists of a vortex crushing chamber and coarse, medium, and fine crushing sections. The motor drives the rotor to rotate at high speed via a V-belt transmission. Materials enter the crusher chamber through the feed opening and are struck by the high-speed rotating rotor hammer plates. They are then impacted against the toothed counter-plate at the top of the vortex crushing chamber, rebound, and freely fall. This process continues as the materials collide with subsequent upward-moving materials, resulting in further crushing. Large pieces of material that have not been sufficiently crushed are subjected to enormous pressure and bending force generated by the thick tooth plates and hammer plates at the top of the crushing chamber, ensuring that even difficult-to-crush materials are easily crushed in the coarse crushing stage and then enter the next stage for further crushing.

Structural Composition of the Vortex High-Power Impact Crusher:

1. Machine body  

The frame is a welded structure, with sawtooth-shaped impact plates lining the crushing chamber. When material impacts, it generates bending and breaking forces, resulting in improved crushing efficiency compared to flat impact plates. Replaceable liners are installed on both sides to protect the machine body from wear. The upper machine body features a tall curved structure, forming a unique vortex crushing chamber. The upper left and right frames are connected by bolts, with threaded rods or hydraulic opening devices installed depending on the model size. Maintenance access doors are provided on both sides of the upper and lower frames and in front of the feed opening, facilitating maintenance and replacement of wear parts.  

2. Drive System  

High-protection-rated motors are used, along with narrow V-belts with effective widths. The motor's movable slide rails allow adjustment of belt tension.  

3. Rotor Assembly

The rotor assembly is the core component of this crusher. The rotor body is fabricated from structural steel plates with a hard alloy welded layer on the wear surfaces;

the rotor shaft is made from special forged material and undergoes heat treatment. The main shaft pulley can be mounted on the left or right (depending on user requirements), with the right-hand mount being the standard configuration. The rotor body and rotor shaft are connected via a tapered sleeve instead of traditional keys, enabling easier disassembly and providing overload protection;

The rectangular high-efficiency hammer plates, made from special wear-resistant materials, are supported tangentially to prevent breakage and can be flipped for reuse, maximising efficiency;

The hammer plates are secured by wear-resistant wedges and embedded into the rotor body, automatically clamping during operation for easy installation and quick replacement.
