At Mazandaran Steel Industries, we manufacture and supply spare parts for Horizontal Shaft Impact (HSI) Crushers using high-quality raw materials and advanced heat treatment technologies. These parts, with exceptional wear resistance and long service life, are the best choice for maximizing the efficiency of your production lines.
The HSI Crusher (Horizontal Shaft Impact Crusher) is an impact crushing machine that breaks materials by striking and throwing rocks against impact plates. It is primarily used in the secondary or tertiary crushing stages and is ideal for producing sand and fine aggregates.
Operating Principle of the HSI Crusher
- The rotor rotates at high speed.
- Rocks enter the machine through the feed inlet.
- The rotor is equipped with hammers that strike the rocks at high speed.
- Rocks are thrown against impact plates and break upon collision.
- Crushing occurs through a combination of primary impact, secondary collision, and frictional effects.
- Crushed materials are discharged from the bottom of the machine.
- Selecting the appropriate hammer depends on the material type, hardness, abrasiveness, capacity, and desired shape.
Applications of the HSI Crusher
- Production of sand and aggregates
- Crushing limestone, dolomite, gypsum, and soft to medium-hard rocks
- Recycling concrete and asphalt
- Producing materials for asphalt and ready-mix concrete
The HSI Crusher is a powerful machine for impact crushing and producing aggregates with cubical shape and uniform grading. Proper selection of hammer type, adjustment of impact distance, correct feeding, and regular maintenance significantly improve part life, product quality, and reduce operating costs.
