A High Fine Double Vertical Shaft Impact Crusher (VSI Crusher) is an advanced crushing machine designed for producing high-quality, finely shaped aggregates and sand. It utilizes two vertical shafts equipped with rotors and anvils to achieve efficient particle-on-particle crushing, resulting in superior cubical end products.
Key Features:
1. Double Vertical Shaft Design
– Uses two rotating shafts to enhance crushing efficiency and throughput.
– Ensures better particle distribution and finer output compared to single-shaft models.
2. High Fine Output
– Optimized rotor speed and chamber design maximize fines production.
– Ideal for manufactured sand (M-Sand) production in concrete and asphalt applications.
3. Rock-on-Rock & Rock-on-Iron Crushing
– Adjustable configurations allow for different crushing modes:
– Rock-on-Rock: Particles collide with each other for natural shaping.
– Rock-on-Iron: Particles impact metal anvils for higher reduction ratios.
4. Energy Efficiency & Low Wear
– Advanced rotor design minimizes wear on components.
– Reduced operational costs due to optimized energy consumption.
5. Adjustable Gradation Control
– Speed regulation of rotors allows precise control over product size distribution.
– Suitable for producing sand with specific fineness modulus requirements.
6. Versatile Applications
– Aggregate shaping (cubical particles).
– Manufactured sand production.
– Mineral processing (e.g., limestone, basalt, granite).
– Recycling (concrete, glass).
Advantages Over Conventional Crushers:
- Produces more uniform, well-graded sand with fewer flaky particles.
- Lower operational noise and vibration compared to horizontal shaft impactors.
- Higher reduction ratio with minimal fines generation when needed.
