Horizontal impact crushers and vertical impact crushers are two different types of impact crushers used for crushing various materials. Here are some key differences between horizontal and vertical impact crushers:
Orientation: As the names suggest, the main difference between horizontal and vertical impact crushers is the orientation of the rotor. In a horizontal impact crusher, the rotor rotates horizontally parallel to the ground, while in a vertical impact crusher, the rotor rotates vertically perpendicular to the ground.
Crushing principle: Horizontal impact crushers use impact force to crush materials against the blow bars on the rotor, which then throw the materials against the breaker plates installed on the outer shell of the crusher. Vertical impact crushers, on the other hand, use the principle of "rock on rock" or "rock on metal" crushing, where the rotor accelerates the materials to high speed and throws them against a stationary anvil or impact plates, resulting in crushing by impact and attrition.
Design and size: Horizontal impact crushers are typically larger and heavier machines compared to vertical impact crushers. Horizontal impact crushers are designed for high production capacities and can handle large feed sizes, making them suitable for primary and secondary crushing applications. Vertical impact crushers, on the other hand, are generally smaller and lighter, and are often used for tertiary or quaternary crushing where fine product sizes are desired.
Application: Horizontal impact crushers are commonly used in applications where the feed material is relatively soft and non-abrasive, such as limestone, gypsum, and soft ores. They are widely used in the mining, quarrying, and recycling industries. Vertical impact crushers, on the other hand, are often used in applications where the feed material is hard and abrasive, such as granite, basalt, and hard ores. They are typically used in the production of high-quality, cubical-shaped aggregates for concrete and asphalt production.
Particle shape: Horizontal impact crushers tend to produce a more cubical product shape due to the impact crushing mechanism, which is suitable for applications where a well-shaped product is desired. Vertical impact crushers, on the other hand, may produce a more elongated and flaky product shape due to the crushing by impact and attrition, which may be suitable for some specific applications, but not for all.
Maintenance and wear parts: Maintenance requirements and wear parts for horizontal and vertical impact crushers can also differ. Horizontal impact crushers typically have a higher number of moving parts and wear parts, such as blow bars, breaker plates, and curtains, which may require more frequent maintenance and replacement. Vertical impact crushers, on the other hand, typically have a simpler design with fewer wear parts, which may result in lower maintenance requirements and costs.
In summary, horizontal impact crushers and vertical impact crushers have key differences in their orientation, crushing principle, design and size, application, particle shape, and maintenance requirements. The choice between a horizontal and vertical impact crusher depends on the specific crushing application, material characteristics, desired product shape, and other factors, and should be carefully considered based on the requirements of the particular crushing operation.
