The vertical impact crusher and the vertical composite crusher have significant differences in structure

　　The vertical impact crusher and the vertical composite crusher have significant differences in structure, working principle, applications, and performance characteristics.
　　Structural Differences
　　Vertical Impact Crusher: Small round chamber, vertical installation of the main shaft, no discharge grate, unable to control the discharge particle size, requires a large amount of return material and vibrating screen to work together to control the discharge particle size.
　　Vertical Composite Crusher: Large chamber, three-curved surface crushing, horizontal installation of the main shaft, with discharge grate, can effectively control the discharge particle size.
　　Differences in Working Principles
　　Vertical Impact Crusher: Adopts two crushing mechanisms of "stone hitting stone" and "stone hitting iron." The material is accelerated by the high-speed rotation of the impeller and thrown out from the discharge port, where it collides violently with the material falling from the overflow port in the circumferential area of the impeller, resulting in crushing.
　　Vertical Composite Crusher: During operation, the material falls from the feed hopper onto the throwing plate, and after being impacted by the high-speed rotating throwing plate ribs, it is thrown towards the impact plate under the action of centrifugal force. The material collides with each other in the crushing chamber and is gradually crushed from large to small.
　　Differences in Applications
　　Vertical Impact Crusher: Suitable for shaping stone materials, with good results, but a small crushing ratio.
　　Vertical Composite Crusher: Widely used for fine crushing and sand making operations of stone materials, with a smaller discharge particle size.
　　Differences in Performance Characteristics
　　Vertical Impact Crusher: Features a large crushing ratio, high crushing efficiency, and uniform product particle size, suitable for crushing materials below medium hardness.
　　Vertical Composite Crusher: Simple structure, easy maintenance, larger feed particle size, smaller discharge particle size, suitable for fine crushing and sand making operations, low energy consumption, and the internal structure uses high hardness, high toughness multi-alloy wear-resistant hammers and liners, resistant to wear and impact, with a long service life.
　　In summary, the vertical impact crusher and the vertical composite crusher each have their advantages in structure, working principle, applications, and performance characteristics. Users should choose the appropriate equipment based on specific needs.
