Vertical Shaft Impact Crushers

Vertical shaft impact crushers (VSI) are high-performance machines designed to produce 0-5 mm sand and gravel from medium-hard and abrasive materials. The crushing process involves a high-speed rotating rotor that throws the material against a stone lining in the crushing chamber. This stone-on-stone crushing method is highly efficient, resulting in reduced spare parts consumption and lower operational costs, making it an economical choice for various applications.

Key Features of Vertical Shaft Impact Crushers:

• High Performance: Ideal for producing fine sand and gravel from medium-hard and abrasive materials.
• Stone-on-Stone Crushing: Reduces wear and tear, resulting in lower maintenance costs.
• Economical Operation: Low spare parts consumption and reduced operational costs ensure cost-efficiency.

Turbo Crushers

Turbo crushers are specifically designed for crushing abrasive materials and function as tertiary crushers in crushing plants. They are known for producing cubic-shaped materials with a high reduction ratio. Depending on the material and application, the crushing chamber can be configured in three distinct layouts:

1. Stone Padded Layout with Closed Rotor: Best for the hardest and most abrasive materials, offering the lowest maintenance costs.
2. Closed Rotor Armor Circle Layout: Suitable for medium-abrasive and medium-hard materials, combining the durability of a closed rotor with the efficient reduction provided by the armor circle.
3. Open Rotor Armor Circle Layout: Ideal for softer, less abrasive materials, this layout offers the highest reduction rate and greater production capacity.

Rotor Types

Rotors for VSI crushers are available in two designs, depending on the abrasiveness of the material:

• Closed Rotor: Recommended for hard and abrasive materials. The material forms a protective layer on the rotor's inner surfaces, minimizing wear. Diamond throwers made of wear-resistant materials further reduce maintenance, making it ideal for crushing highly abrasive materials.
• Open Rotor: Suitable for softer, less abrasive materials, offering a higher reduction rate and larger feed capacity. This design maximizes production capacity while maintaining ease of maintenance.

Applications of Vertical Shaft Impact Crushers:

Vertical shaft impact crushers are highly versatile and can be used in various applications, including:

• Crushing natural stones from stream material.
• Reducing feed material sizes for milling processes.
• Producing cubic-shaped aggregates in limestone, basalt, and dolomite quarries.
• Manufacturing sand, gravel, and pebbles for concrete and asphalt production.
• Producing fine materials for road asphalt structures.
• Reducing the size of coke in steelmaking, enhancing carbon content in liquid steel.

Efficient Tertiary Crushing

Vertical shaft crushers are often used as tertiary crushers in crushing and screening plants, efficiently breaking down hard stones such as stream material, basalt, and limestone into sand or gravel. Both open and closed rotor designs use a stone-on-stone impact mechanism, where stones collide with each other, resulting in efficient material reduction.

These crushers come equipped with hydraulic systems for easy maintenance, enabling quick access for repairs and component replacements. With capacities ranging from 90 to 450 tons per hour, vertical shaft crushers offer high efficiency and low energy consumption, making them a top choice for high-capacity operations.

Easy Maintenance and Accessibility

Maintenance is made simple with the hydraulic piston system, allowing the breaker door to be easily opened. This design ensures quick and hassle-free maintenance, reducing downtime and improving operational efficiency.
