Polygonmachine PV Series Vertical Shaft Impact Crushers

Key Features

• High-Efficiency Direct Drive System: Maximizes energy transfer from motor to rotor, minimizing power loss and ensuring smooth, continuous operation.

• Exclusive Polygonmachine Rotor Design: Accelerates material efficiently into the crushing chamber, reducing wear on internal parts while maintaining precise particle shaping and high crushing performance.

• Adjustable Crushing Configurations: The PV Series supports both rock-on-rock and rock-on-steel setups, enabling operators to adapt to various materials and end-product specifications.

• Advanced Vibrational Control: Balanced rotor design reduces operational vibration and noise, increasing structural lifespan and improving safety during high-speed operations.

• Easy Maintenance Liner System: Modular and replaceable wear liners allow for quick maintenance, minimizing downtime and maintaining consistent production flow.

• Precision Particle Shaping: Rotor velocity and chamber geometry ensure consistent cubic product with minimal fines generation.

Performance and Efficiency

• Rotor Speed Range: 1000–2500 rpm (model dependent)

• Reduction Ratio: Up to 1:20

• Feed Hardness: Up to 450 MPa

• Specific Energy Consumption: 0.5–0.7 kWh/ton
