Introduction

VSI Crusher

Vertical Shaft Impact Crusher (VSI Crusher) is an advanced and energy-efficient crushing machine that utilizes centrifugal force and high-speed impact to break down materials. During operation, materials are fed into a high-speed rotor, which accelerates them and projects them outward at high velocity. The particles then collide with a surrounding rock bed (rock-on-rock) or impact plates (rock-on-steel), leading to multiple stages of fragmentation and shaping.

VSI crushers are widely used for the final stage of crushing in the production of high-quality manufactured sand and well-graded aggregates, especially for hard and abrasive materials like granite, basalt, and quartz. The unique crushing principle enables the production of cubical particles with excellent shape and consistency, making VSI ideal for concrete, asphalt, and other demanding applications.

In addition to superior product quality, VSI crushers offer advantages such as adjustable output size, low dust generation, easy maintenance, and reduced energy consumption. With their high reliability and performance, they are essential equipment in modern sand and aggregate production lines.

Working Principle

The vertical shaft impact crusher (VSI) operates on the principle of high-speed rotor acceleration and material self-impact. During operation, materials are fed into the center of the rotating rotor. The rotor, spinning at high speed, flings the materials outward through centrifugal force toward the crushing chamber.

Once ejected, the materials collide either with a surrounding rock lining (rock-on-rock) or impact plates (rock-on-steel), depending on the crusher configuration. These high-velocity impacts cause the materials to fracture and break into smaller, well-shaped particles.

This repeated process of acceleration, impact, and rebound produces high-quality, cubical aggregates and manufactured sand. The final particle size can be controlled by adjusting the rotor speed and the type or layout of the impact surface. VSI crushers are widely used for fine crushing and shaping in industries such as construction, mining, and sand making.

Features

New Process Design

Adopting a new four-port design, compared with the three-port impeller, the crushing efficiency of the same material is increased by 20%, and the wear on wear-resistant parts is reduced

Energy Saving

Deep cavity rotor design, greater throughput, self-circulation of airflow inside the vortex cavity, less dust and low noise

One Machine With Multiple Functions

The sand making and shaping of the special rotor can be freely converted, and the peripheral guard plate can be removed for hard rock stone shaping, and the flake rate is greatly reduced; the peripheral guard plate can be used for hard rock sand making

High Output

Reasonable material impact angle design in the crushing chamber reduces energy consumption and use costs, and increases output per hour
