Introduction of Vertical shaft impact crusher
VSI Vertical shaft impact crusher or Vsi Sand making machines are widely used in metal and non-metal ores, cement, refractory materials, abrasives, glass raw materials, construction aggregates, artificial sand making, river pebbles, rocks (limestone, granite, basalt, diabase, andesite, etc.), ores Artificial sand making of tailings and stone chips, construction aggregates, road surface materials, bedding materials, asphalt concrete and cement concrete aggregate production, and various metallurgical slag fine crushing and rough grinding operations, especially for medium-hard and extra-hard And abrasive materials such as silicon carbide, emery, sintered bauxite, magnesia, etc., are more superior than other types of crushers.
Used in conjunction with hydraulic protection jaw crusher, it can handle all kinds of metallurgical slag.
It is suitable for construction sand and sand and gravel for road construction.
Working principle of Vertical shaft impact crusher
The working principle of the impact crusher is simply the principle of rock-to-stone. Let the stones collide with the stones accelerated by the impeller in the natural falling process, so as to achieve the purpose of crushing. When the accelerated stones collide with the naturally falling stones, a vortex is formed, and it is broken twice during the return process, so the machine's counterattack plate wears very little during the operation.
The stone falls directly into the high-speed rotating turntable from the upper part of the machine. Under the action of high-speed centrifugal force, it splits with another part of the target stone around the turntable in an umbrella manner to produce high-speed impact and high-density crushing. After the stones hit each other, It will also form a vortex motion between the turntable and the casing, causing multiple blows, frictions, and smashes, which are discharged directly from the lower part. It forms a closed circuit for multiple cycles, and is controlled by the screening equipment to achieve the required particle size.
Performance characteristics of Vertical shaft impact crusher
1. This machine is a new type of medium and fine stone crushing equipment developed in the 1990s, and it is also a model widely used in the world to replace cone crushers and counter-rollers.
2. The structure is novel, unique and balanced in operation.
3. Low energy consumption, high output and large crushing ratio.
4. The equipment is small in size, easy to operate, easy to install and maintain.
5. It has the function of shaping, the product is cubic, and the bulk density is large.
6. During the production process, the stone can form a protective bottom layer, the machine body is wear-free and durable.
7. A small amount of easy-wearing parts are made of super hard and wear-resistant materials, which are small in size, light in weight and easy to replace parts.
