HSI (Horizontal Shaft Impact) crushers are a type of impact crusher that utilize high-speed rotating hammers or blow bars to crush materials. They are widely used in aggregate production, recycling, and mining applications due to their high reduction ratios and ability to produce well-shaped cubical products.
Key Features of HSI Impact Crushers:
1. Horizontal Shaft Design – The rotor spins horizontally, delivering high-speed impacts to the feed material.
2. High Reduction Ratio – Capable of reducing large feed sizes into smaller, uniform particles.
3. Cubical Product Shape – Produces more evenly shaped aggregates compared to compression crushers (e.g., jaw or cone crushers).
4. Adjustable Settings – Allows control over product size by adjusting the rotor speed, curtain spacing, and blow bar configuration.
5. Versatility – Can handle soft to medium-hard materials like limestone, recycled concrete, asphalt, and coal.
Applications:
– Aggregate Production (quarries, sand & gravel)
– Recycling (concrete, asphalt demolition waste)
– Mining & Minerals Processing
– Industrial Applications (glass, ceramics)
