Frequently Asked Questions
-
A stationary HSI (Horizontal Shaft Impact) crusher is a fixed crushing unit that uses impact force to break down materials. It consists of a high-speed rotor fitted with blow bars that hurl the feed material against stationary impact plates (aprons) mounted in the crushing chamber . This impact action causes the material to break along its natural cleavage planes, producing excellent, stress-free, cubical-shaped products with low flake and elongation ratios . HSI crushers are typically used in primary (feed sizes up to 400-2000 mm) and secondary crushing applications for soft to medium-hard materials such as limestone, recycled concrete, and asphalt
-
Stationary HSI crushers are versatile and can process a wide range of materials:
Limestone and soft to medium-hard rocks: Ideal for aggregate production with feed sizes up to 400-2000mm
Reinforced concrete: Ability to handle re-enforced steel bars, enabling recycling of both steel and aggregate
Asphalt: Can recycle old road surfaces for inclusion in new asphalt products
C&D waste: Effective for construction and demolition debris recycling
Low abrasive materials: Suitable for materials with low abrasion index
-
The choice between HSI and cone crushers for secondary crushing depends largely on material characteristics:
Product shape: HSI crushers produce superior cubical shapes with low flakiness through impact crushing, making them ideal for high-quality concrete and asphalt aggregates.
Material suitability: HSI crushers excel with soft to medium-hard, low-abrasion materials like limestone and recycled concrete. Cone crushers are preferred for hard, abrasive materials where wear costs must be minimized.
Feed size: For secondary operations, maximum feed size for cone crushers could be estimated at 12% of the mainframe opening, while HSI crushers can accept feed up to 39% of the rotor diameter.
In short: Choose HSI for soft to medium materials and superior cubical shape, especially in recycling. Choose cone for hard, abrasive materials where wear costs must be minimized over long-term, high-capacity operations.
-
The core difference lies in their role: primary crushers reduce large material, while secondary crushers refine it into finished products.
Feed size: Primary HSI crushers accept run-of-quarry material directly from the blast site, with large feed openings. Secondary HSI crushers process material already reduced by a primary crusher, accepting smaller feed sizes.
Design: Primary crushers feature robust rotors and heavier blow bars for high-impact reduction. Secondary crushers are optimized for higher speeds and precision shaping.
Application: Primary HSI crushers excel in soft to medium-hard materials like limestone, often replacing both jaw and cone crushers. Secondary HSI crushers produce superior cubical shapes for high-spec aggregates and excel in recycling applications.
In short: Primary HSI crushers break material down. Secondary HSI crushers shape it up.
