Description

Description

The Vertical Shaft Sand Making Machine, also called Impact Crusher (VSI),  is a powerful machine used for producing high-quality sand and aggregates. It operates by using a high-speed rotor to accelerate materials, which are then impacted against anvils or rocks to break down and shape the particles. The VSI is widely used in sand making, gravel production, and mining industries. Known for its high efficiency, low maintenance, and ability to produce cubical, fine materials, it is ideal for applications requiring consistent grain sizes and high-quality output.

Features

✅ Superb Crushing Power & Ideal Shape
Combining “rock-on-rock” + “rock-on-steel” crushing technology with a 3D crushing cavity design, it ensures uniform particles with less than 5% needle content — perfect for premium-grade sand production.

⚡ Energy-Saving, Cost-Effective
Engineered with an optimized power system and upgraded chamber structure, it reduces energy consumption by 20–30% compared to traditional machines. Plus, wear-resistant alloy parts extend service life by 50%!

🔄 One Machine, Multiple Applications
Crush over 200 types of stones — from granite to basalt — and support output from 50 to 500 tons/hour.

Working Principle of VSI

The Vertical Shaft Sand Making Machine consists of seven parts: a feeding hopper, a distributor, a vortex crushing chamber, an impeller body, a main shaft assembly, a base, a transmission device, and a motor.
The material falls vertically into the high-speed rotating impeller from the upper part of the machine. Under the action of high-speed centrifugal force, it will collide with another part of the material shunted around the impeller in the form of an umbrella. The material forms a vortex between the casings, collides and rubs each other many times, is crushed, and is directly discharged from the lower part to form a closed circuit for multiple cycles. After being controlled by the screening equipment, the finished product reaches the required particle size.
