What is a VSI Crusher?
VSI Crusher, also known as Vertical Shaft Impact Crusher, mainly achieves crushing by using a high-speed rotor to drive multiple alloy blades on the rotor, accelerating small pieces of rock and other materials, and then throwing them toward the fixed wall of the crushing chamber. As a key equipment in the crushing application field, VSI crusher machine is widely used in construction, mining, quarrying, and recycling industries.
Product Introduction
As an innovative work of impact crushing technology, the high-efficiency vertical shaft sand making machine drives the materials with a high-speed rotating impeller to achieve dual crushing of "stone impacting stone" and "stone impacting iron". It is specially designed for sand making and shaping of medium-hard to extremely hard materials such as river pebbles, granite, and basalt. Through the self-lining design of the vortex crushing cavity, the equipment realizes multi-level impact and grinding of the materials. The content of cubic finished products exceeds 90%, the proportion of needle-like and flaky materials is less than 5%, and the fineness modulus is controllable, fully meeting the strict requirements of high-end projects such as high-speed railways and airports for the particle shape of aggregates.
Working principle
VSI stone crusher is a very efficient crushing equipment, which is mainly composed of key components such as electric motor, reducer, impact plate, hammer head, base and screen plate.
When the VSI crusher is running, the electric motor drives the device through the speed reducer, and the hammer head mounted on the rotor rotates at a high speed driven by the centrifugal force, hitting the impact plate with strong kinetic energy and crushing the material on the surface of the impact plate into fine particles or powder. During the whole crushing process, the material has experienced many impacts and collisions between the hammer head and the impact plate, and its particle size keeps decreasing until it reaches the standard of particle size required for production.
The core of the working principle of VSI rock crusher lies in the impact crushing mechanism, where the material breaks and crushes due to the strong collision between the high-speed rotating hammer head and the impact plate. In addition, the unique design of VSI crusher can ensure the uniform distribution of the strength of the crushed material, effectively improve the overall crushing efficiency, so as to meet the material crushing needs of various production scenarios.
Structure
Core technical advantages
Intelligent Crushing System
The dual-mode crushing cavity ("stone impacting stone"/"stone impacting iron") can be switched with just one click, adapting to both abrasive materials (such as quartzite) and non-abrasive materials (such as limestone), increasing the sand formation rate by 20%. The impeller rotation speed can be intelligently adjusted and controlled (1050-2210r/min), with a crushing ratio reaching 50:1. The hourly output of a single machine is 30-1000 tons, featuring the three functions of primary crushing, fine crushing, and shaping.
Convenient Hydraulic Operation and Maintenance
The hydraulic cover opening device enables quick disassembly and maintenance within 15 minutes. The service life of wear-resistant parts (high-chromium alloy impeller, diamond-shaped combined throwing head) is extended by 3 to 5 times, and they can be turned over for reuse after one side is worn. The thin oil lubrication system has dual oil pumps that supply oil complementarily, and the bearing temperature is controlled at a constant level (15℃-50℃). It automatically heats up in winter to prevent coagulation, ensuring 24-hour continuous operation.
Energy-saving and Low-consumption Design
The vortex airflow self-circulation system reduces dust emissions by more than 90%, and the energy consumption is 30% lower than that of traditional sand making machines. With the optimized design of the impeller (the material flow rate is increased by 25%), the output is increased by 30% under the same power, and the iron pollution in the "stone impacting stone" mode approaches zero.
Intelligent Monitoring and Protection
The PLC intelligent control system monitors vibration, oil temperature and current in real time, and provides automatic shutdown protection in case of overload. The accuracy rate of excessive vibration early warning is 99%. It supports remote operation and maintenance, and the fault response speed is increased by 80%.

Application scenarios✓Fine
VSI crushers, also known as vertical impact crushers, are suitable for crushing most materials. Their primary uses include quarries and gravel sites, where they are mainly employed to produce artificial sand for road asphalt, concrete, and aggregates for the construction industry. In today's environmentally conscious era, all industries must learn to recycle waste materials. With proper equipment for reprocessing, this can become a highly profitable sector.
High-quality Aggregates
Basalt aggregates for expressways, graded crushed stones for high-speed railways, and high-strength sand and gravel for airport runways.
Solid Waste Utilization
Resource utilization of construction waste, and ultra-fine powder processing of steel slag/slag.
Industrial Raw Materials
Single-stage crushing of cement clinker, and high-purity shaping of glass quartz sand.
Green Mines
Equipped with an intelligent screening system to achieve precise grading of 0-5mm and 5-10mm, with dust emissions less than 10mg/m³.
VSI cone crusher are typically used to produce high-quality aggregates for constructing bridges, buildings, tunnels, and other structures. They are critical components in manufacturing artificial sand and crushed sand. As natural sand mining is now limited and sand is a scarce resource on Earth, an increasing amount of sand needs to be manufactured or crushed to meet demand.
