Impact Crushers
Aury Africa supplies a complete range of impact crusher spares and support solutions for secondary and tertiary crushing applications across mining, quarrying, recycling, and construction industries. Impact crushers are designed to deliver high reduction ratios by applying powerful dynamic forces to break down medium-hard to soft materials. They are especially valued for producing cubical-shaped products and for their ability to handle materials with varying levels of abrasiveness and moisture.
With their unique ability to simultaneously crush and shape material, impact crushers are commonly used where final product quality, gradation, and consistency are critical.
What Are Impact Crushers?
Impact crushers operate by using blow bars mounted on a rapidly spinning rotor to strike incoming material and force it against stationary breaker plates (aprons) or impact walls. The material shatters upon contact and is further reduced as it rebounds within the crushing chamber. This repeated collision process allows for fast, efficient size reduction, producing uniform aggregates and fines suitable for a variety of downstream uses.
There are two main types of impact crushers: horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSIs are typically used for primary and secondary crushing, while VSIs are employed for tertiary or quaternary applications where shaping is critical.
Support, Optimization, and Services
Aury Africa offers complete technical support and wear optimization services for impact crushers. We assist clients with blow bar material selection based on application and feed characteristics, rotor and chamber adjustments for optimal output, and scheduled maintenance planning.
Our team can also analyse wear patterns to help extend component life and improve overall crushing efficiency. Stockholding, wear monitoring, and predictive maintenance strategies are available to ensure parts availability and reduce downtime during critical production windows.
Spare Parts and Wear Components
Aury Africa supplies premium impact crusher spare parts and wear liners, including blow bars, impact plates, rotor assemblies, side liners, bearings, and shaft components. Manufactured to OEM standards for wear resistance, impact strength, and dimensional accuracy, these components ensure reliable crushing performance and reduced downtime.
Applications Across Industry
Impact crushers are widely used in:
-
Aggregate production (limestone, dolomite, and gravel)
-
Construction and demolition recycling (concrete, brick, asphalt)
-
Mineral processing (soft rock and coal reduction)
-
Road base and sub-base preparation
-
Cement and building materials production
Their ability to reduce oversized feed and simultaneously produce well-graded fines makes them a key part of many material preparation and recycling systems.
Performance and Advantages
Impact crushers deliver high reduction ratios and produce clean, well-shaped material ideal for concrete, asphalt, road base, and softer materials like limestone or coal. With fewer moving parts, easy maintenance access, and adjustable aprons and rotor speeds, they provide efficient, versatile performance in multi-stage crushing applications.
