The Vertical Shaft Impact Crusher series from Pyramids is the ideal choice for the final stage of crushing and screening processes. These crushers are known for their high production capacity and excellent performance in processing wet, sticky, and moist materials. Additionally, the materials fed into the crusher experience a reduction in moisture content due to the kinetic energy generated when colliding with the rotor, which operates at high speed. This results in relatively drier final materials. Thanks to these advantages, the crushers are highly sought after for producing sand and gravel required in the manufacture of concrete and asphalt. They are available in various configurations, including fixed steel legs, fixed chassis, or front-feed designs, depending on facility requirements.
Crusher Body
The crusher body is designed with a welded structure, ensuring long-lasting durability and high strength. Due to its high-speed operation, the body is mounted on a sturdy chassis with wedges to reduce the effects of vibrations produced during operation.
Ease of Maintenance
A hydraulic system located adjacent to the body allows the upper section of the crusher to open effortlessly, facilitating quick and efficient maintenance. Additionally, a control cover on the body provides easy access for servicing.
Feeding Chute
The feeding chute is positioned at the initial impact point inside the crusher and ensures uniform material distribution. This design extends the lifespan of the rotor components by reducing wear and tear.
Rotor Unit
The rotor is protected from abrasion by upper and lower plates. It is also equipped with three layers of artificial diamonds to enhance resistance to wear.
Advantages of the Crusher:
- High production capacity with low energy consumption.
- Artificial diamond liners for enhanced resistance to wear.
- Anti-vibration systems for stable operation.
- High percentage of cubic-shaped final materials.
- Quick and easy maintenance facilitated by the hydraulic system.
- Simple installation and user-friendly operation.
- Reduced noise and environmental impact.
Closed Rotor Design
The closed rotor design of the vertical shaft impact crusher is ideal for processing all types of stones and highly abrasive materials. The internal surfaces of the rotor are lined with cast material, while the discharge nozzles are reinforced with abrasion-resistant diamonds that are easy to replace.
This design operates based on the “rock-on-rock” principle, where material is crushed by impacting against other material. The material enters through a circular inlet, lands on the distribution liner in the center of the rotor spinning at high speed, and is propelled outward by strong centrifugal force. The high-velocity material is directed into the crushing chamber, where it collides with other material in the stone box, achieving efficient size reduction. This mechanism ensures low wear on spare parts and high efficiency.
Open Rotor Design
The open rotor design of the vertical shaft impact crusher is ideal for crushing materials with light to moderate abrasiveness. Unlike the closed rotor design, this configuration features an open upper section and uses steel-cast liners arranged at specific angles and distances within the body instead of a stone box.
Material enters the crusher through a feeding tube and lands on the distribution liner at the rotor’s center. The rotor’s blades accelerate the material and direct it toward the side liners. Crushing occurs as the material impacts the liners, and the reduced material is discharged through the chute.
