Vertical Shaft VSI Impact Crusher 8518 Sand Maker Machine for Aggregate Shaping

The Vertical Shaft VSI Impact Crusher 8518 is a high-capacity sand maker and aggregate shaper built around a closed rotor and hardened wear parts. Material is fed either centrally or through both center and sides; the rotor hurls the rock against a stone-lined crushing chamber, where particles fracture along natural weaknesses to yield cubical, well-graded sand and chips. The two feeding modes let operators balance throughput, product shape and wear cost. Widely used in manufactured-sand lines and concrete aggregate plants, the VSI delivers consistent, specification-grade material with low flakiness and a strong particle surface.

• Dual Feeding Modes: Center or center-plus-side feeding lets you trade capacity against product shape and wear cost to suit each application.
• Superior Cubical Shape: Rock-on-rock fragmentation produces cubical particles with low flakiness, raising the quality and value of concrete aggregate.
• Self-Lining Crushing Chamber: An autogenous stone lining absorbs impact and protects the machine body, reducing metal wear and maintenance frequency.
• Stable High-Speed Rotor: A dynamically balanced rotor and precision bearings run smoothly at high speed for reliable, continuous output.
• Adjustable Gradation: By changing rotor speed and feed mode, the fineness modulus and gradation of the sand can be tuned to match specification.
• Compact Robust Chassis: The heavy fabricated chassis and short shaft drive keep the machine stable and easy to install on a simple foundation.

The VSI crusher is the core of manufactured sand production lines and a key shaping stage in high-grade concrete aggregate plants. It is also used in mineral processing, in glass and refractory sand production, and in the recycling of construction waste. Wherever cubical shape, controlled gradation and dependable high throughput are required, the VSI is the machine of choice.

The crusher is delivered with the rotor and wear parts protected, and the drive components boxed separately. A complete set of rotor tips and a wear-plate kit are available on request. Each unit is test-run before shipment. Our twelve-month warranty and responsive parts service help you maintain steady sand and aggregate output.
