Product Overview

The VSI Vertical Shaft Impact Crusher is a high-performance crushing equipment for artificial sand making and material shaping. With 35-600t/h capacity, it efficiently crushes granite, river pebbles, and ore via impact principle, delivering uniform particle size and excellent shape. Featuring intelligent control, low energy consumption, and easy maintenance, it’s widely used in mining, construction, and aggregate production, ideal for high-quality sand and gravel projects.

Key Advantages

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.

Working Principle

Large pieces of ore fall from the feeding hopper into the upper throwing tray in the upper crushing cavity, and the material is thrown to the inner wall of the cylinder by the centrifugal force of the throwing tray, and collides violently with the counter board installed on the inner wall. At the same time, the materials collide with each other, causing them to break or generate a large number of capillary cracks. Then after entering the conical rotor cavity, the material spirally falls in the conical space, and the crushed ore is further crushed by punching and extrusion. Due to the inclination between the conical rotor and the liner, the smaller materials will move downward, and the graded crushing from big to small can be realized automatically. When the material is hit by the hammer head in the conical rotor cavity, the high-speed running block material collides with the impact plate again, and the material flow collides with each other, so that the material is crushed by impact, collision, shearing and extrusion, and the crushing rate is improved. efficiency.

Frequently Asked Questions

A VSI crusher uses a high-speed rotating rotor to accelerate materials, which then collide with impact blocks or other materials. It supports two crushing principles: "rock-on-rock" (material self-impact for shaping) and "rock-on-iron" (material impacting metal anvils for higher reduction).

It has a high crushing ratio (up to 50:1), produces excellent cubical particles with needle flake content below 10%, handles both soft and hard materials, and features selective crushing—higher density materials break into smaller sizes.

Wear parts like hammers and impact plates wear quickly. Also, when material moisture exceeds 9% or contains sticky components, it may cause build-up on impact surfaces and reduce efficiency.

VSI crushers are known for producing highly cubical, well-graded particles with a low needle/flake content — typically below 10–15%. This makes the output ideal for high-specification concrete aggregates, asphalt mixes, and railway ballast.
