Introduction to Vertical Impact Crusher
The vertical shaft crusher differs in structure and working principle from conventional jaw crushers, cone crushers, and roller crushers, which are all types of forced crushing equipment. It also differs from conventional ball mills and autogenous and semi-autogenous mills, which are probabilistic grinding equipment. Furthermore, it is distinct from traditional impact crushers and hammer crushers, making it a new type of impact crusher.
Applications of Vertical Impact Crusher
The vertical shaft crusher is widely used for both metallic and non-metallic ores, cement, refractory materials, abrasives, glass raw materials, construction aggregates, artificial sand making, river pebbles, rocks (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, stone chips for artificial sand production, construction aggregates, highway pavement materials, bedding materials, asphalt concrete, cement concrete aggregates production, and fine crushing and coarse grinding operations of various metallurgical slags.
It is particularly suitable for processing medium-hard, extremely hard, and abrasive materials such as silicon carbide, emery, sintered bauxite, and magnesite, outperforming other types of crushers. When used in conjunction with hydraulic protection jaw crushers, it can handle various metallurgical slags. It is especially recommended for building sand and road stone materials.
Working Principle of Vertical Impact Crusher
Material is vertically dropped from the top into the high-speed rotating impeller of the vertical impact crusher. Under the effect of high-speed centrifugal force, it collides and crushes with another part of the material that is distributed in an umbrella shape around the impeller, resulting in high-speed impact and crushing. After mutual impact, the material then forms a vortex between the impeller and the casing, causing continual mutual impact and friction until it is crushed and discharged directly from the bottom. This process forms a closed-circuit multiple cycles, controlled by screening equipment to achieve the desired particle size of the final product.
Advantages of Vertical Impact Crusher
Good particle shape of the finished product: The vertical shaft crusher employs impact crushing principles, allowing for increased crushing and minimal grinding. Impact crushing not only has a crushing function but also a certain micro-shaping effect. The sand and gravel handled by this equipment have uniform particle sizes, low needle flake content, reasonable grading, and can be used directly.
Durable and easy to adjust: The hammer head of the vertical impact crusher is wear-resistant, with a unique locking structure that provides good impact resistance and wear resistance, ensuring stable discharge particle size.
Comprehensive crushing functions with high overall efficiency: The heavy-duty rotor structure of the vertical shaft crusher significantly improves the crushing rate, offers high output, and encompasses comprehensive crushing abilities to meet requirements for coarse, medium, and fine crushing. The overall efficiency is high.
High production, energy-saving, and low cost: The vertical impact crusher can crush materials on-site, avoiding intermediate steps of crushing material far from the site, thereby effectively reducing production and operation costs.
