VSI vertical shaft impact crusher working principle

Introduction:

VSI is the abbreviation of Vertical Shaft Impact. Vertical shaft impact crusher is an efficient fine crushing and shaping equipment, mainly used for crushing and shaping of medium and high hardness materials. It is widely used in sand and gravel production, mining, construction, building materials and other industries, especially in the field of artificial sand making and stone shaping. It ejects the material through the high-speed rotating rotor, and crushes the material through impact, collision and friction. Compared with other types of crushers, VSI crusher has a unique structure and working principle.

Working principle:

Material enters the crushing chamber: The material enters from the feed port of the crusher and falls on the high-speed rotating rotor. The rotor is the core component of the VSI crusher, usually driven by a motor, with a very high speed (up to 60-70 m/s).

Rotor accelerates the material: The rotor in the crusher rotates at high speed and accelerates the material through centrifugal force. The material is thrown to the impact plate or liner in the crushing chamber.

Material impact and crushing: The material hits the material, and the materials collide with each other during the ejection process to achieve self-crushing. This method is suitable for materials with higher hardness and the finished product has a better particle shape. The material hits the impact plate, and the material directly hits the metal impact plate fixed in the crushing chamber. This method is suitable for occasions that require higher crushing efficiency.

Material discharge: The crushed material is discharged through the screen plate or the discharge port, and the unqualified material will be recycled and crushed again. In addition, the particle size of the finished product can be controlled by adjusting the gap of the screen plate or the speed of the rotor.

Features of VSI crusher:

Good particle shape and high efficiency: It mainly adopts two high-efficiency crushing principles, stone hitting stone and stone hitting iron, which can not only improve production efficiency, but also have excellent particle shape of crushed materials.

Environmental protection: The equipment has a simple structure and good sealing, low relative energy consumption and noise, and less dust, which meets environmental protection requirements.

Controllable particle size: By adjusting the rotor speed and the gap of the screen plate, the particle size of the material can be flexibly controlled.

Easy maintenance: Due to its simple structure, easy maintenance and operation, and long component replacement cycle, it greatly reduces labor and input costs.

Wide adaptability: It is suitable for crushing materials of various hardness, especially when processing medium-hard or soft materials.

In short, the design of the vertical shaft impact crusher enables it to efficiently and accurately complete multiple tasks such as fine crushing and shaping. Its working principle is simple and efficient, and it uses the impact and collision between the material and the impact plate or other materials to achieve crushing. It is suitable for crushing medium and high hardness materials, and the finished product has excellent particle shape. It is widely used in sand making, mining and building materials industries.
